How to Varnish Pottery
To varnish pottery made of air dry clay, there are several options available.
PVA glue and Mod Podge can be used as sealants, but they offer little water resistance.
For a more durable and water-resistant finish, polyurethane and acrylic sealers are recommended.
To create a DIY varnish, mix clear nail varnish, clear glue, and water.
For a colored glaze effect, add acrylic paint to the varnish.
Before varnishing, ensure that the pottery is sealed, dry, and free from dust.

Did You Know?
1. Did you know that the ancient Egyptians were one of the first civilizations to varnish pottery? They used a mixture of beeswax and resin to seal and protect their pottery from chipping and moisture damage.
2. In Japanese pottery, there is a traditional method called “hidasuki” for creating unique patterns with varnish. This technique involves tightly wrapping the vessel with straw rope before applying the varnish. The heat generated during firing burns the straw and leaves behind delicate red or black lines on the pottery.
3. The famous Ming Dynasty porcelain pottery from China featured a type of varnish made from plants called “jǔní,” which gave the pottery its distinctive glossy finish. This technique was considered a closely guarded secret, and only a select few artisans were entrusted with this knowledge.
4. Varnishing pottery not only enhances its appearance but also helps to preserve its contents. During the Middle Ages, European apothecaries would often varnish their ceramic jars and containers to protect the medicinal substances inside from light and moisture.
5. The Spanish town of Manises, renowned for its ceramic production, played a significant role in the development of varnishing techniques. In the 16th century, local artisans began experimenting with a tin-based varnish called “loza de Manises,” which gave their pottery a lustrous and durable finish, setting their work apart from other European pottery of the time.

Importance Of Sealing Air Dry Clay
Air dry clay is a non-toxic material commonly used for crafting, but it is important to note that it is not food safe and requires a sealant for protection. Leaving air dry clay objects unvarnished can lead to issues such as peeling, chipping, fading, and dust accumulation, which can significantly affect their appearance and durability. To prevent these problems, it is crucial to apply a sealant to the clay. This will make the pottery more resistant to wear and tear, allowing it to be displayed in any environment without worries. Furthermore, if paint or color has been added to the clay’s surface, a sealant is necessary to preserve the design and avoid flaking or smudging.
To summarize the key points:
- Air dry clay is not food safe and needs a sealant for protection.
- Unvarnished air dry clay objects are prone to peeling, chipping, fading, and dust accumulation.
- Applying a sealant makes the clay more resistant to wear and tear.
- A sealant preserves the design and prevents flaking or smudging, especially when paint or color is involved.
Sealant Options For Air Dry Clay
When it comes to sealant options for air dry clay, there are several choices available. Two popular options are PVA glue and Mod Podge. However, while PVA glue and Mod Podge offer some protection, they do not provide sufficient water resistance.
For the best results, polyurethane and acrylic sealers are recommended. These sealants provide a durable and water-resistant finish, protecting the pottery from moisture and preventing yellowing. Opting for a polyurethane varnish or acrylic sealer ensures long-lasting preservation of the air dry clay pottery.

Frequently Asked Questions
Can we use varnish on pottery?
Yes, varnish can indeed be used on pottery, especially when utilizing cold finishes for non-fired decorations. The application of varnish serves the dual purpose of safeguarding and augmenting the decorative elements on ceramic pieces. By applying varnish, the pottery is shielded from potential damage while simultaneously enhancing the visual appeal of the decorative elements, resulting in a more durable and aesthetically pleasing finished product.
How do you varnish clay?
To varnish clay, start by allowing it to fully dry. Then, you can use a foam brush or paintbrush to apply a thin layer of varnish. It is important to let each layer dry for about five to six hours before adding another layer. Repeat this process, allowing ample drying time in between layers, until you achieve the desired glossy glazed finish.
How do you make pottery shiny?
To achieve a shiny finish on pottery, one method is to rub the clay surface with a polished stone or a smooth object. Applying consistent pressure and circular motions during the rubbing process helps to smooth out any imperfections and create a shiny surface. Another technique involves using terra sigillata, a specially prepared clay slip, to coat the pot. After applying the terra sigillata, gently rubbing it with a soft material like chamois leather helps to polish the surface and enhance its shine. Both methods require attention to detail and careful handling to achieve the desired shiny result.
What varnish is best for clay?
Finding the best varnish for clay can be a bit tricky due to the wide range of clay brands available. Many varnishes, glazes, and sealers may not be suitable for every brand of clay. However, if you do require a sealer, there are several options that offer maximum compatibility. PYM II, Helmar Crystal Kote Matte, Varathane, Pearl Ex Varnish, and Cernit MATTE varnish have been found to work well with all clay brands, ensuring a successful and long-lasting finish to your clay creations.
