Potash Feldspar - 500g
Potash Feldspar is typically used in clay bodies to help them vitrify. In glazes, it's used to aid melting at medium to high temperatures. Potash Feldspar melts at around 1200°C, which is higher than soda feldspar, and creates a thicker melt. It can also form crystals that make the glaze more opaque. Because of this, potash feldspar is often used for matte glazes, while soda feldspar is chosen for glossy glazes.
