G2571A Cone 10 Dolomite Matte Glaze

Description

A balanced dolomite matte for reduction firing (although it works well in oxidation also). It is better than any other dolomite recipe we have ever used.

  • Unlike many, this does not have excessive feldspar to make it craze. It thus works on all high fire Plainsman clay bodies.
  • It has a lower LOI than many others that have higher dolomite content and add calcium carbonate on top of that. This employs wollastonite to source extra CaO.
  • The small amount of Gerstley Borate improves melting without increasing thermal expansion, the product is a surface that does not cutlery mark or stain.
  • The MgO content is not excessive so the surface is not too matte.
  • This accepts colors to create many beautiful effects better than others because it is melted better.
