Explore our collection of ceramic fluxes in the UK, essential raw materials used in the formulation of pottery glazes and clay bodies. Fluxes are a core component of ceramic chemistry, responsible for lowering the melting temperature of silica and other glass-forming materials, allowing glazes to mature properly in kiln firings.

This collection includes a wide range of key ceramic flux materials such as feldspars (potash feldspar, soda feldspar), frits, borates, carbonates, and other glaze melting agents. Each material contributes differently to glaze behaviour, affecting melt fluidity, gloss level, colour response, texture, and thermal expansion.

Whether you're developing studio glaze recipes, studying ceramic chemistry, or refining production materials, fluxes are fundamental to achieving reliable and expressive ceramic results.

Browse our full range of ceramic fluxes and discover essential materials for glaze formulation and pottery making.
