Can I double glaze pottery?

Double glazing pottery is a technique that involves applying two layers of glaze to a ceramic piece, enhancing its aesthetic appeal and durability. This method can create unique visual effects and improve the pottery’s resistance to wear and tear.

What is Double Glazing in Pottery?

Double glazing refers to the process of applying two separate layers of glaze on a ceramic piece, typically after the first glaze has been fired. This technique can add depth and complexity to the surface of the pottery, offering a more vibrant and intricate finish.

Benefits of Double Glazing Pottery

• Enhanced Visual Appeal: Double glazing can create a multi-layered effect, giving pottery a more dynamic and textured appearance.
• Improved Durability: The additional layer of glaze can help protect the pottery from scratches and chips.
• Unique Effects: Combining different glazes can result in unique color blends and surface textures.

How to Double Glaze Pottery

To successfully double glaze pottery, follow these steps:

1. Select Compatible Glazes: Ensure the two glazes you choose are compatible in terms of firing temperature and chemical composition.
2. Apply the First Glaze: After bisque firing your pottery, apply the first glaze layer evenly. Allow it to dry completely.
3. Fire the First Glaze: Fire the piece according to the first glaze’s specifications, usually at a lower temperature.
4. Apply the Second Glaze: Once the first glaze has cooled, apply the second glaze layer. Experiment with different application techniques for varied effects.
5. Final Firing: Fire the piece again, this time according to the second glaze’s specifications. This will fuse both layers together.

Tips for Successful Double Glazing

• Test First: Always test your glaze combinations on a small piece to ensure they interact well.
• Consider Shrinkage: Be mindful of how each glaze shrinks during firing to avoid cracking.
• Experiment with Techniques: Try different application methods like brushing, dipping, or spraying to achieve desired effects.

Common Mistakes in Double Glazing

• Incompatible Glazes: Using glazes that are not chemically compatible can result in defects like crazing or peeling.
• Improper Firing: Firing at incorrect temperatures can cause glaze defects or even damage the pottery.
• Over-application: Applying too much glaze can lead to dripping or pooling, which may ruin the piece.
