Ash

Ash

Ash is the mineral residue left after the combustion of organic materials, such as wood or bones. These ash particles can be incorporated into clays, glazes or during modeling. Ash can add unique textures, colors and physical properties to pieces, depending on its chemical composition and the way it is integrated into the clay or glaze. In addition, ash can act as a flux, helping to reduce the melting temperature of materials in the glaze and promoting more uniform vitrification during firing. This can improve the durability and water resistance of ceramic pieces, as well as add a gloss or matte finish depending on the technique used. The inclusion of ash can also influence the texture and final appearance of the piece, providing interesting visual effects that complement the overall design.

Interesting Fact

In traditional African ceramics, especially in Malian and Nigerian village pieces, ash is used to create natural glazes that give the pieces unique, glossy finishes. These ash-based glazes not only provide distinctive aesthetics, but also improve the water resistance of the pieces, allowing them to be used in humid environments and increasing their durability.

Helpful Tip

When working with ash in ceramics, be sure to clean it properly to remove impurities that may affect the quality of the piece. Mix the ash evenly with the clay or glaze for consistent results and test fire to understand how the ash interacts with other components of the mix.
