Ravenscrag Cone 6 Raspberry Glossy
Recipe
Notes
Chrome-tin (either from the raw materials or a stain) pink and red glazes can be difficult to achieve and keep consistent at cone 6. Red is perhaps the most difficult and expensive color in ceramics. The chemistry of the host glaze has to be sympathetic to the color development, the chrome and tin require high calcium, zero zinc and low boron (that is why this recipe has 10% added calcium carbonate). Remember that red is red, it is difficult to acheive in glazes; test this first on different kinds of clay to determine if is is suitable for you. It may be better for you to use a pink or maroon stain instead instead of raw chrome and tin (e.g. the GR6-L recipe). Try different thicknesses to see which works best for you. This breaks clear around edges to highlight irregularities in the surface. On darker bodies the color of the glaze will be darker. Consider reducing the percentage of colorant to get a lighter color if needed. Slow cooling can matte the surface. For mixing and firing instructions please see the master recipe, GR6-A.
