Botz Pro 9622 Amethyst Ceramic Glaze

Botz Pro 9622 Amethyst creates a rich purple glaze finish on pottery. At higher firing temperatures the shade softens and the surface becomes more glassy.

Botz Pro Glazes

Botz Pro is a range of ready-to-use brush-on ceramic glazes with a broad firing range of 1020–1280°C, suitable for both earthenware and stoneware. Their appearance changes with firing temperature. At around 1050°C, colours are generally stronger and almost opaque. At around 1150°C, they retain their colour while becoming more semi-transparent. At around 1250°C, they develop a glossier, glass-like surface with softer, pastel tones. For most colours, Botz recommends 2–3 coats at 1050°C and two coats at around 1150–1250°C. Thick application can cause the glaze to run, especially from 1150°C upwards. The manufacturer recommends the range for tableware, provided the glaze is fired correctly and is compatible with the clay body. Test the result on a sample before glazing finished work.
