G2934 Matte Cone 6 Glaze
For Stonewares and Porcelains
A dolomite matte for cone 6. Like a cone 10R dolomite matte, the surface of this is very silky and it resists cutlery marking well (in our firing at cone 6). This does not fire white, it is translucent, it has no opacifier. If you want pure white, add Zircopax (start with 5%). Keep the zircon at a minimum (it contributes to cutlery marking).
This recipe also has very good suspension and application properties. We find a specific gravity of about 1.4 to be good. Glaze samples shown here are porcelain.
Almost certainly, the degree of matteness will not be quite right for you. If this is too matte (most likely), blend in some of either of the clear glossy bases (G2926B, G2916F). G2934 is an excellent color base and works particularly well with inclusion stains. However, each different color you create using this base will also likely require fine tuning of the degree of matteness. It is already quite matte so you will not likely want any more (since this could make it stoney and non-functional).
Screening: We have not ball milled this product, thus it will contain some oversize particles from the constituent materials. We advise that you screen your glaze slurry to at least 80 mesh when you make the glaze and periodically after that.
The recipe of this glaze is not proprietary. We developed it and sell it premixed but if you want to batch it yourself, please feel free to do so.
