Alternative Methods For Glazing Pottery At Home
There is something magical about pottery, and the glazing process gives it a beautiful, polished finish. However, not everyone has access to a pottery kiln to glaze their pottery. Fortunately, there are alternative methods that you can use at home to achieve a glazed look without the need for a kiln.
One such alternative is using acrylic paint. Acrylic paint provides vibrant colors and is readily available at art supply stores. It can be applied directly to the pottery surface using brushes or sponges. After application, the pottery can be air-dried or baked in a regular oven at a low temperature to help set the paint.
Another option is using oil-based paints, wax, or epoxy resin. These materials can also be applied to the pottery’s surface and offer different finishes and textures. Oil-based paints give a glossy finish, while wax provides a more traditional look. Epoxy resin offers a durable and glossy finish.

Using Acrylic Paint As An Alternative To Ceramic Glazes
Acrylic paint is a versatile and user-friendly medium that can serve as an excellent substitute for traditional ceramic glazes. It offers a wide array of colors and can be mixed to create custom shades. When applied to unglazed pottery, acrylic paint yields a smooth and vibrant finish.
To begin, cleanse the pottery thoroughly and ensure it is completely dry. Utilize a soft brush or sponge to apply the acrylic paint in thin layers, ensuring even coverage across the entire surface. Allow each layer to dry before proceeding to the next. Once the desired color intensity is achieved, follow the manufacturer’s instructions to allow the paint to fully cure.
While acrylic paint can deliver a beautiful finish, it is crucial to seal the painted pottery in order to safeguard the paint from wear and moisture damage. Additionally, utilizing a sealant will enhance the longevity of the piece.
Other Alternatives: Oil-Based Paints, Wax, And Epoxy Resin
Apart from acrylic paint, there are other alternatives you can explore to finish your unglazed pottery.
One option is oil-based paints, commonly used for painting on canvas but also suitable for pottery. These paints provide a glossy and durable finish and can be brushed on or applied using a sponge.
Another alternative is wax. Wax can be applied to the pottery’s surface, creating a protective layer that also enhances its appearance. It can be buffed to achieve a polished finish, giving pottery a timeless look.
Epoxy resin is an excellent choice for finishing pottery as it creates a clear, glossy, and durable surface. It is typically applied in layers and allowed to cure between each layer. Resin can be poured or brushed onto the pottery’s surface, providing a smooth and professional finish.
- Oil-based paints: glossy and durable finish, can be brushed on or applied with a sponge
- Wax: protective layer, enhances the appearance, can be buffed for a polished finish
- Epoxy resin: clear, glossy, and durable surface, applied in layers, can be poured or brushed for a professional finish

Applying A Sealer For Water-Resistant Pottery
Applying a sealer to unglazed pottery is crucial to enhance its water resistance and protect its painted surfaces. There are various sealers available, each with its own advantages and recommended applications.
One option is a clear acrylic sealer, specifically designed for ceramics and pottery. This sealer creates a protective barrier that enhances the longevity of the piece. Apply the sealer according to the manufacturer’s instructions, ensuring even coverage over the entire surface. Allow it to dry and cure completely before exposing the pottery to moisture.
Another recommended sealer is a waterproof spray sealer. This type of sealer creates a water-resistant barrier and is ideal for functional pottery that may come into contact with water. Simply spray the sealer, holding the can an appropriate distance from the pottery, and move in a smooth and even motion. Allow the pottery to dry completely before using or displaying it.
- Apply clear acrylic sealer for enhanced longevity
- Use waterproof spray sealer for functional pottery
- Follow manufacturer’s instructions for application
- Allow proper drying and curing time before exposing to moisture
Recommended Sealants For Acrylic Paint On Pottery
When it comes to sealing acrylic paint on pottery, it is important to choose a compatible sealant that provides the desired level of protection. Not all sealants are suitable for acrylic paint, so it is essential to select the right one for your specific project.
One popular option is a clear acrylic sealant. This type of sealant is available in various finishes, such as matte, satin, or gloss. It creates a protective layer over the acrylic paint, enhancing its durability and longevity. Apply the sealant in thin layers, allowing each layer to dry before applying the next.
For a more water-resistant finish, epoxy resin can also be used as a sealant. This two-part resin creates a durable and glossy surface that can protect the acrylic paint from wear and moisture damage. Be sure to follow the manufacturer’s instructions for mixing and applying the epoxy resin.
Achieving A Metallic Look With Boot Polish And Bronze Metallic Powder
If you want to give your unglazed pottery a unique metallic look, there are several techniques you can try. One method involves using boot polish and bronze metallic powder to create an antique or aged appearance.
Start by cleaning the pottery and allowing it to dry completely. Apply a layer of boot polish to the surface, using a soft cloth or brush. Allow the boot polish to dry to a haze before buffing it with a clean cloth to remove excess polish.
Next, create a mixture of bronze metallic powder and a small amount of clear acrylic paint. Apply the mixture to the pottery using a soft brush or sponge, achieving the desired metallic effect. Allow the metallic powder to dry and set before applying a clear sealant to protect the finish.
By experimenting with different techniques and finishes, you can transform your unglazed pottery into stunning works of art. Whether you choose acrylic paint, oil-based paints, wax, or epoxy resin, each option offers a unique way to showcase your creativity and add a professional touch to your pottery.
Frequently Asked Questions
How do you seal pottery without a kiln?
One alternative method to seal pottery without a kiln is by using an open pit firing technique. In this process, a pit is created, and a charcoal grill can serve as a suitable option. Once the pit fire reaches the desired temperatures, the pottery is carefully placed within the heat and left for a specific duration, ranging between 12 to 24 hours, based on the desired finish. As the intense heat interacts with the pottery, it helps to seal and cure the clay, resulting in a hardened and durable vessel. This traditional method not only ensures the pottery’s longevity but also adds a unique and rustic charm to the finished product.
Can you use unglazed pottery?
Yes, unglazed pottery can indeed be used. When using midrange (stoneware) and highfire clays, the unglazed surfaces can still be considered foodsafe if they are fired to their full maturity. The clay particles in these clays vitrify enough during firing, creating a waterproof surface that meets safety standards. So, while unglazed pottery may lack the traditional protective glaze, it can still be used confidently for food-related purposes.
Can you wash unglazed pottery?
Yes, unglazed pottery can be washed without causing any harm. The use of soap and water will not damage the bowl. However, it is important to avoid letting the pottery sit in dirty water for extended periods as cone 6 clays have the potential to absorb enough water to grow mold. By taking precautions and ensuring the pottery is properly dried after washing, you can maintain the cleanliness and integrity of the unglazed pottery.
Can pottery be glazed without firing?
No, pottery cannot be glazed without firing. Firing in a kiln is an essential step in the glazing process as it allows the glaze to melt and bond to the clay, creating a smooth, durable, and finished surface. Without firing, the glaze would not adhere properly to the pottery, resulting in a fragile and ineffective finish. Kiln firing not only ensures the pottery’s functionality but also contributes to its aesthetic appeal by enhancing the colors and textures of the glaze.
