Cone 10 Silky Dolomite Matte glaze
Recipe
Notes
A standard Plainsman Clays cone 10R dolomite matte glaze used for many years. Colorants and opacifiers can be added to create a wide range of beautiful classic earthy reduction effects. The bamboo effect, made by the addition of 3.5 rutile and 10 Zircopax, is probably the most popular. Many dolomite (or talc) matte glazes do not have a proper chemistry balance and do not melt to a stable glass; crazing, cutlery marking and staining are common problems. This one, by contrast, has a very silky surface yet exhibits none of these problems. An alternative recipe (but very similar chemistry) using Ravenscrag Slip is also available. If you do not have Gerstley Borate or Wollastonite it is pretty easy to alter the recipe to source CaO calcium carbonate (instead of wollastonite) and B2O3 from a frit instead of GB.
