Reactive glazes (codes beginning 2320-) can be used as low temperature stoneware glazes fired between 1180 and 1230C, or as underglazes - covered with higher temperature glazes - which combine during stoneware firing to give excellent combination effects.

Reactive Slip 2394-01M is intended for use underneath various stoneware glazes to give varied reduction effects in electric firings and can be applied to biscuit or leatherhard clay. For glaze preparation advice please see the main powdered glaze category header here.

The 'Mineral' range of stoneware glazes fires in the range 1180-1230C and are semi-matt, becoming shinier with increased temperature.

All stoneware glazes are leadless and suitable for dinnerware, but for practical reasons we don’t recommend matt or special effect glazes are used on surfaces in direct contact with food or drink due to the possibility of staining and/or bacterial growth.
