What is Glaze in Ceramics

Glaze is a liquid coating applied to pottery or ceramic ware before a final firing. During this firing, the glaze melts and transforms into a smooth, glass-like layer on the ceramic surface. This glaze layer offers several benefits:

  • Aesthetics: Glaze comes in a wide range of colors, allowing for artistic expression and customization.
  • Waterproofing: Glaze fills the pores in the clay body, making the pottery watertight and functional for holding liquids.
  • Durability: Glaze strengthens the pottery, making it more resistant to scratching, chipping, and staining.

What is Glaze Made of?

Glaze is a mixture of silica, fluxes, and metal oxides that melts into a smooth, glass-like surface during the firing process. The role of each ingredient:

  • Silica: This forms the glassy base of the glaze, providing structure and a smooth surface.
  • Fluxes: These materials lower the melting point of the glaze, ensuring it fuses with the clay body during firing.
  • Metal Oxides: These introduce color to the glaze. Different metal oxides produce various colors, and the glaze chemistry and firing conditions can also influence the final color.

Types of Pottery Glazes

Glazes can be categorized based on their visual effects:

  • Gloss Glazes: Create a shiny, reflective surface, perfect for adding a lively sparkle to your pieces.
  • Matte Glazes: Offers a low or absent sheen for a subdued look. It’s often used for sophisticated design.
  • Satin Glazes: Provides a subtle sheen with a smooth texture, ideal for everyday items.
  • Specialty Glazes: Like crystalline and raku, they offer unique effects and textures.

Firing temperature is another crucial factor. Glazes are formulated to reach their optimal properties at specific temperature ranges:

  • Low-fire (Cone 06-04): Fired at lower temperatures (1828°F to 1940°F), these glazes offer a broader color palette but may be less durable.
  • Mid-range (Cone 5-6): Fired at moderate temperatures (2167°F to 2232°F), these glazes balance color and durability.
  • High-fire (Cone 10): Fired at the highest temperatures (2345°F), these glazes create the most durable and waterproof surfaces, ideal for high-use pottery. They may have a more limited color range.

Where to Buy Glaze

Finding the right glaze for your pottery project is a crucial step that can significantly impact the final result. Here is a breakdown of some reliable sources from which you can buy your glaze.

  • Check Reviews: Read reviews from other potters to get insights into the glaze’s performance before making a purchase.

How to Make Pottery Glaze at Home If You Don’t Want to Buy One

For those interested in creating custom glazes, here’s a basic overview of the process and materials needed:


  • Silica: Provides the glassy base for the glaze.
  • Alumina: Controls the viscosity and prevents the glaze from running.
  • Flux: Lowers the melting point to allow the glaze to fuse with the clay. Common fluxes include feldspar, whiting, and dolomite.
  • Metal Oxides: Introduce color to the glaze.


  • Digital Scale: Ensures accurate measurements of ingredients.
  • Sieve: Removes lumps from the glaze mixture for a smooth application.
  • Safety Gear: Protects you from inhaling dust particles. Gloves, goggles, and a mask are recommended.

Steps of Making the Glaze:

Safety First!

Remember, some glaze materials can harm you if you breathe or swallow them. Wear gloves, goggles, and a mask to protect yourself, and work in a space with good air circulation.

Formulate Your Recipe: A good starting point is a basic clear glaze recipe for cone 6 (mid-range) firing:

  • Feldspar (Potash) – 40%
  • Silica (Flint) – 30%
  • Whiting – 20%
  • Kaolin (China Clay) – 10%

Add colorants like copper carbonate (2% for a soft green tint) based on the dry weight of your base glaze for color.

Weigh the Ingredients: Use a digital scale for accuracy.

Mix and Sieve: Blend dry ingredients, then add water to achieve the consistency of heavy cream. Sieve to remove lumps.

Test: Apply a bit of glaze to a small tile and fire it in your kiln. This way, you can see the final color and how the glaze works with your clay before you glaze your whole project.

Remember, making your own glazes is all about trying new things and having fun! Don’t be afraid to experiment with different colors and base mixes to find what works best for you.

How to Glaze Pottery

Here is a step-by-step tutorial on glazing pottery, including different glazing techniques.

Bisque-Fire Your Piece

Bisque firing is the process of firing clay pottery in a kiln without glaze at a temperature usually between 1720°F and 1940°F (check your clay’s instructions for the exact temperature), high enough to harden the clay but low enough to keep it porous. This initial firing changes the chemical composition of the clay, making it more durable and ready to absorb glaze efficiently. Here’s how to do it:

  • Make Sure It’s Dry: Your pottery must be completely dry before it enters the kiln. Any leftover moisture can make it crack or even explode!
  • Careful Placement: Put your pottery on special shelves inside the kiln, with space between each piece. This lets air flow around them while baking.
  • Just the Right Heat: Bisque firing usually happens between 1720°F and 1940°F (check your clay’s instructions for the exact temperature). It needs to be hot enough to harden the clay but not so hot that it blocks the glaze later.
  • Slow and Steady Wins the Race: Increase the heat in the kiln slowly at first. This helps any leftover moisture escape safely without cracking the pottery.
  • Let it Cool Down: Once it’s done baking, turn off the kiln and let it cool down naturally. Opening it too soon can cause the pottery to crack from the sudden temperature change.
  • Checking Your Work: After everything cools down, take a look at your pottery. It should feel firm and have a light, even color. Any cracks or bumps can affect how the glaze looks later.

Prepare the Pottery and Glaze

To achieve a successful glaze application, it’s important to prepare both the pottery and the glaze itself properly. The following steps will guide you through this process.

Prepare the Pottery

Following bisque firing, ensure your pottery is completely clean and dust-free. You can wipe the piece surface gently with a slightly damp sponge to remove any debris that might prevent the glaze from adhering uniformly.

Additionally, consider the following for areas you don’t want glazed (optional):

  • Wax Resist: Apply a layer of wax resist to areas you don’t want glazed, such as the bottom or specific design elements. This prevents the glaze from sticking to these parts and is crucial for places that will rest on kiln shelves, as glaze can cause the pottery to stick to the shelf.
  • Tape or Latex: For more precise application, use painter’s tape or liquid latex to create sharp lines or protect intricate designs. Remove tape or latex after glazing but before firing to leave the protected areas unglazed and maintain the integrity of your design or functional requirements (like keeping the foot of a pot clear to avoid sticking to the kiln shelf).
apply wax resist to unglazed areas

After applying the wax resist or any other masking method, ensure the piece is completely dry before applying the glaze.

Prepare the Glaze

Thorough mixing is essential for even color and consistency, especially with new or settled glazes. Here’s a breakdown of the preparation process for glaze:

  • Mixing: Shake or stir the glaze vigorously to re-incorporate any settled components and achieve a uniform mixture.
  • Sieving: Pass the glaze through a fine-mesh sieve (ideally 80-120 mesh) two to three times. This removes impurities, breaks down clumps, and creates a smooth glaze. Sieving is particularly important for settled or newly mixed glazes.
  • Adjusting Consistency: The ideal glaze consistency depends on the application method. For brushing, it should be similar to cream. For dipping, it can be slightly thinner.
  • Thickening: If the glaze is too thick, add water slowly while mixing well. Avoid adding too much water, which can dilute the glaze and alter firing results.
  • Thinning (Optional): Specific gravity meters (the ratio of the density of the glaze to the density of water) can be used to measure the glaze’s density for optimal consistency (dipping glazes typically fall between 1.4 and 1.5). This step is optional but can ensure consistent results across batches.
  • Resting (Optional): Some potters let the prepared glaze sit for a few hours or overnight. This allows air bubbles to rise to the surface and escape, potentially reducing pinholes in the finished glaze.
  • Final Stir: Before applying the glaze, stir it one last time to ensure all components are well-mixed.

By carefully preparing both your pottery and glaze, you’ll create a foundation for smooth and even glaze application.

Glaze the Pottery: Different Pottery Glazing Techniques Used

1. Brushing

Brushing is a technique for applying glaze to pottery using a paintbrush. It’s perfect for creating precise details or layering different colored glazes for unique effects. Here’s how to brush like a pro:

  • Pick a soft brush. Softer brushes make fewer streaks. Wider, synthetic brushes are great for covering large areas quickly, while finer, natural-bristle brushes excel at detailed work.
  • Dip your brush gently into the glaze, just enough to coat the bristles. Apply the glaze in smooth, even strokes across your bisque-fired (first-fired) pottery. Try to go in the same direction each time to avoid streaks.
  • For flawless, even coverage, do 2 or 3 coats of glaze. Let each layer dry slightly before adding the next. This drying time is crucial – glaze applied to a wet glaze can cause the first layer to lift off, ruining your piece!

Additional Tips:

  • Don’t brush back and forth too much, especially when the glaze is almost dry.
  • Don’t use too much glaze on the brush, which can make drips and uneven layers.


  • Allows for precise control over thickness and coverage.
  • Ideal for adding detailed patterns and designs.


  • Can be time-consuming for larger pieces.
  • May leave brush marks if not done correctly.

2. Dipping

Dipping involves immersing the pottery directly into a container of glaze. It’s a popular way to put the glaze on your pottery because it’s fast and makes the glaze nice and even, particularly useful to glaze a lot of pieces at once.  


Here is how:

Find a container big enough to submerge your pottery in the glaze mixture completely. Hold the pottery with dry hands by an unglazed area, or use dipping tongs specifically designed for this purpose to avoid fingerprints.

Slowly dip your pottery all the way into the glaze and hold it for a few seconds. This lets the glaze evenly coat the surface. Slowly remove your pottery from the glaze, allowing any extra glaze to drip back into the container.

Gently tap your pottery to shake off any remaining drips. This helps prevent bumps or uneven glaze.

Additional Tips:

Your pottery must be clean (free of dust) and dry before dripping. Wet pottery won’t hold the glaze well.

Before dipping, stir your glaze well. This ensures the glaze is smooth and avoids clumps that can leave uneven coverage.


  • Quick and efficient, ideal for glazing lots of pottery at once.
  • Ensures even coverage and thickness.


  • Less control over specific areas of coverage.
  • Requires a lot of glazes

3. Pouring

Pouring glaze is a fantastic technique for quickly covering large areas of your pottery or creating unique, flowing designs. It’s perfect for creating decorative effects with multiple glaze colors.


Here is how:

You’ll need a container with a spout for easy pouring, like a large pitcher or jug. The glaze consistency for pouring should be slightly thinner than the dipping glaze to prevent running.

Hold the pottery piece, ideally something with a shallow inside like a plate or bowl, over a basin or sink to catch any drips.

Smoothly pour the glaze over the piece, tilting and turning it as you go to ensure even coverage across the entire surface. Let the glaze run down the sides of your pottery for complete coverage.

The height from which you pour can affect the outcome—higher pours usually mean a thinner coat and can create a “cascade” effect. Pouring can be particularly useful for large or awkwardly shaped items that are difficult to dip.

Additional Tips:

Be careful not to splash glaze everywhere. Aim for a controlled pour to avoid uneven thickness.

Keep an eye on where the glaze overlaps on your pottery. Too much overlap can create thicker sections that might run during firing.

Always remember to pour slowly and steadily. This gives you the most the control over the flow and distribution of the glaze. You can practice first before real pouring.


  • Quick application for large or complex pieces.
  • Can create unique, fluid patterns.


  • Can be messy and wasteful.
  • Difficult to achieve uniform thickness.

4. Spraying

Spraying uses specialized equipment to apply a fine mist of glaze over the pottery and offers a uniform, smooth coat that can be ideal for complex shapes without brush strokes or dipping marks.


Here is how:

You’ll need a special sprayer, like an airbrush, and a well-ventilated space (or a spray booth) to work safely since tiny glaze bits can fly around.

Fill the sprayer with a thinned glaze mixture; it should be more fluid and thinner than you’d use for brushing or dipping.

Wear a mask or respirator to avoid breathing in the glaze and make sure you’re working in a space with good air circulation.

Apply the glaze in thin coats, allowing it to dry partially between layers to build up a nice, even coat without causing drips. Move the sprayer smoothly back and forth, overlapping each pass slightly like you’re painting.

Additional Tips:

Practice makes perfect. Try spraying on a scrap piece (like cardboard) first to get the hang of the spray pattern and flow rate before applying it to your final piece.

Check your equipment regularly for clogs and clean it well after use so it keeps working properly.


  • Achieves a smooth, even finish without brush marks.
  • Good coverage on intricate or textured surfaces.


  • Requires special tools and has to be carefully and safely handled.
  • Can be challenging to master and requires practice.

5. Stippling

Stippling in pottery glazing is a precise technique where small dots of glaze are applied using the edge or tip of a brush or a sponge to create a textured, often broken, visual effect on the ceramic surface. This method is particularly effective for adding depth and interest to glaze applications.

Here is how:

You’ll need a stiff brush, like the ones used for painting houses or walls.

Dip the brush in the glaze, but not too much. The stippling glaze should be a little thicker than usual to prevent drips.

Hold the brush straight up and down and gently tap it against the pottery surface to make small dots. Keep tapping to add more dots and build up the texture.

Additional tips:

Don’t put too much glaze on your brush; otherwise, it will drip and ruin the design.

Hold the brush or sponge vertically and tap gently instead of scrubbing the brush, or the dots will get too big and lose their texture.


  • Effective for adding depth and interest to surfaces.
  • Highlights specific areas or features on a piece.
  • Creates cool textures by changing how you tap the brush.


  • It takes some practice to get the dots just right.
  • Not suitable for achieving smooth or glossy finishes.
  • May need a lot of work for large areas.

6. Spattering

Spattering is a glazing technique that adds a speckled effect to pottery. It’s done by flicking a stiff-bristled brush dipped in glaze over your piece from a distance.

The size and spread of the spatters can be controlled by the amount of glaze on the brush and the force used to flick it. This technique often adds a final layer of visual interest over a base glaze. It can be very effective in combination with other techniques like brushing or sponging.

Additional tips:

Protect your workspace with newspapers or clothes, as spattering can be messy.

It’d be better to practice your technique first to get a feel for how to adjust the distance and force to control the size and placement of the speckles.


  • A simple and quick way to add texture.
  • Great for layering over other glaze techniques.


  • Can be unpredictable and messy.
  • Less control over the placement and size of specks.

7. Sponging

Sponging is a cool glazing technique using sponges to add texture and blend colors to your pottery. Different sponge textures—from fine to coarse—can produce various effects. Both natural and synthetic sponges can be used.

Dip the sponge lightly into the glaze and dab it onto the pottery. Don’t soak the sponge too much, or the glaze may run.

Additional tips:

Squeeze out any extra glaze from the sponge to avoid overly thick applications that might run.

Try to dab the sponge evenly to avoid getting thick blobs of glaze.


  • Creates organic, varied textures
  • Blends different glaze colors together.


  • It can be tricky to get the glaze perfectly even.
  • The sponge marks might be too bold for delicate designs.
  • You’ll need separate sponges for different colors to avoid them mixing.

8. Trailing

Trailing is a fun glazing process of squeezing glaze from a bottle with a nozzle to create precise lines and patterns on the ceramic surface.

Fill a squeeze bottle with glaze and gently squeeze to trail the glaze over the pottery in your desired pattern. The key is the consistent pressure to ensure the glaze flows evenly from the bottle.

Bottles with different nozzle sizes can create varied line widths. This technique adds artistic detail and enhances the overall design with delicate accents.

Additional tip:

Keep the nozzle clean to prevent blockages; dried glaze can interrupt the glaze flow.


  • Allows for precise line work and detailed patterns.
  • Enables artists to write or draw directly on the piece.


  • Requires steady hands and focus.
  • Best for lines and details, not for quickly covering large areas.
  • Lines may move or blend slightly during firing if not done carefully.

Here are more glazing techniques for you to explore:

Fire Your Piece

Firing is the crucial final step in the pottery-glazing process, where the applied glaze is fused to the clay body at high temperatures, solidifying the design and finishing the piece. This stage not only hardens the clay but also vitrifies the glaze to create a glassy, durable surface.

put the pottery pieces on the kiln shelves

To start the final firing, you’ll need:

  • Kiln: A specially designed oven capable of reaching high temperatures required for firing pottery. There are several types of kilns, including electric, gas, and wood-fired, each offering different atmospheric effects.
  • Kiln Shelves: To place the pottery on, coated with kiln wash to protect from glaze drips.
  • Kiln Posts: To support the shelves and allow placement at various heights, optimizing space and heat distribution.
  • Kiln Cones or Pyrometric Cones: Used to measure the heatwork inside the kiln to determine when the firing is complete.
  • Protective Gear: These include heat-resistant gloves and safety goggles for handling hot ceramics and kiln furniture.

Once you’ve been well-prepared, you can begin the firing. Here is the process:

Step 1 Loading the Kiln

Carefully arrange your bisque-fired and glazed pieces on the kiln shelves. Ensure that pieces do not touch each other to prevent them from fusing together. Use kiln posts to adjust the shelving to accommodate various sizes of pottery. Also, remember not to put too many pieces in the kiln at one time, which can restrict airflow and result in uneven firing.

Maintain adequate ventilation in the area around the kiln, especially in the case of electric or gas kilns, to avoid the buildup of harmful fumes.

Always wear protective gear when loading or unloading the kiln, as pieces and shelves can be extremely hot.

Step 2 Applying Kiln Wash

If not already applied, brush kiln wash on the shelves to prevent glaze from sticking to them. Ensure no glaze is on the bottom of the pieces, as it can melt and stick to the kiln shelves.

Step 3 Setting the Temperature

Program the kiln according to the type of clay and glaze used. Different clay bodies and glazes mature at different temperatures, typically ranging from Cone 022 (about 1087°F) to Cone 10 (about 2345°F).

Step 5 Monitoring the Firing

Use pyrometric cones to monitor the progress. These cones will bend at specific temperatures, indicating the maturity of the glaze and clay.

Step 6 Cooling Down

The cooling process begins after reaching the target temperature and the cones are bent. Allow the kiln to cool slowly and naturally. Rapid cooling can cause thermal shock and crack the pottery.

How to Glaze Pottery at Home in a DIY Kiln

Glazing and firing pottery at home lets you experiment and complete the ceramic process yourself. It requires setting up a DIY kiln, firing the pottery with careful planning, and adhering to safety measures.

Set Up a DIY Kiln

For most home studios, electric kilns are the preferred choice due to their convenience and precise temperature control. The size of the kiln you choose will depend on the typical size of your pottery pieces and the space you have available. Compact tabletop kilns are ideal for small items and limited spaces, while larger freestanding kilns can handle bigger projects.

Once you’ve selected your kiln, it’s crucial to install it in a well-ventilated area to manage heat and fumes effectively. A garage or a covered outdoor space can work well. The floor where the kiln will reside should be fireproof, with concrete being the most suitable option. You’ll likely need a dedicated electrical circuit to power the kiln, so consulting a licensed electrician is essential to ensure compliance with local codes and safety standards.

Adequate ventilation is critical to safely operating a kiln at home. Set up a vent system that expels fumes outside to maintain a safe indoor environment. This can be as simple as fitting an extraction fan in a window or installing a commercial kiln vent.

Firing Pottery

After glazing your bisque-fired pottery as we mentioned, carefully load it into the kiln, ensuring that no pieces touch each other during the firing process.

Program your kiln according to the specific clay and glaze you used. This typically involves a gradual increase in temperature to reach the desired peak, followed by a soak period to ensure even glaze maturation, and finally, a controlled cooling phase to prevent thermal shock to your pottery.

While many modern kilns have digital controls that manage the firing cycle automatically, it’s still recommended to monitor the kiln, especially during your initial firings. This helps you understand how your specific kiln behaves. You can check the kiln periodically through the peephole or use witness cones placed inside the kiln to gauge the heat’s effect on your pottery.

DIY Kiln Alternatives

For those who prefer a more hands-on approach or need a lower-cost solution, building a Raku kiln with a metal trash can and a natural gas or propane burner is a viable option. Raku firing allows for rapid heating and cooling, creating beautiful and often unpredictable glazing effects.

Another alternative is using a barrel or pit firing setup. This traditional method uses organic materials and an open flame to create unique color patterns and textures, without the help of electricity.

  • Always use protective gear when operating the kiln, including heat-resistant gloves and eye protection.
  • Never leave the kiln unattended during operation, as the high temperatures can pose a risk of fire.
  • Be patient with the cooling process. Opening a kiln too early can cause your pieces to crack due to thermal shock.

How to Glaze Pottery Without a Kiln

While traditional kilns are the standard for achieving glazed pottery, alternative methods exist for hobbyists or those lacking access to firing facilities. These methods offer unique creative possibilities but present distinct challenges.

Cold Finishing Techniques

Acrylic Paints and Sealants: This simple method uses acrylic paints to mimic the glaze look. A clear acrylic sealant provides a glossy finish. However, this technique is best for decorative pieces due to limited durability and heat resistance.

Cold Glazes: Commercially available cold glazes offer a kiln-fired glaze appearance and can be applied to bisque ware. These glazes are generally air-dried and then sealed with a top coat for enhanced durability.

Epoxy Resin: Epoxy resin can be used to create a thick, glossy coating resembling a high-gloss glaze. It’s waterproof and durable, but may not be food-safe and requires proper ventilation due to potentially harmful fumes.

Alternative Firing Techniques

DIY kiln

Pit Firing: An ancient method involving burning organic materials around pottery placed in a pit. While not achieving traditional glossy glazes, pit firing can introduce smoke patterns and earthy tones. Color effects can be enhanced with oxides or salts.

Raku Firing: A low-firing process where red-hot pottery is removed from a kiln and placed in containers with combustible materials. This outdoor method creates unique crackled glaze effects. Raku glazes are formulated for this process and offer vibrant colors and metallic finishes.

Important Things to Remember for Non-Kiln Glazing:

  • Pottery fired without a kiln won’t be as durable as pottery fired in a kiln. It’s best for things you won’t use for food or drinks.
  • Raku firing can be dangerous, so always follow safety instructions and wear protective gear.
  • Make sure any paints or sealants you use are safe for what you’re making. Don’t use anything that could be harmful if it touches food. Always check product labels for safety information and intended use.

Additional Glazing Tips for Beginners

Glazing pottery is both an art and a science. While experience is key, specific actions can significantly improve your results. Here are some actionable tips:

1. Glaze Chemistry Knowledge

Understanding the components of your glaze helps predict outcomes. Knowing how materials melt at different temperatures can prevent runny glazes while understanding colorants helps achieve desired hues. Research common glaze materials and their properties.

2. Thorough Glaze Mixing

Proper mixing ensures consistent application. Use a drill with a mixing attachment for thorough stirring. Afterward, strain the glaze through a sieve to eliminate lumps and debris. This prevents pinholing or uneven coating on your pottery.

3. Prevent Resist Spots

Clean your bisque ware thoroughly before glazing. Oils from your hands can create “resist spots” where the glaze won’t stick. Wash your hands well or wear nitrile/latex gloves to prevent natural oils from interfering with the glaze.

4. Generous Glaze Application

When using a brush, ensure it’s well-loaded for smooth, even application. Similar to painting a wall, a full brush provides better coverage. Replenish the glaze frequently to maintain consistency.

5. Detailed Glazing Records

Keep detailed notes or a glazing journal. Record glaze batches, application techniques, firing temperatures, and any other variables. Photos of finished pieces help link visual results to specific methods. This documentation helps replicate successes and troubleshoot issues.

6. Managing Drips on Dry Pieces

If you notice drips or excess glaze, wait for them to dry entirely before addressing them. Wiping wet glaze can smear and ruin the finish. Once dry, carefully scrape them off with a small tool like a pottery rib or knife, avoiding damage to the underlying bisque ware.
