Matte Cone 6 Glaze
For Stonewares and Porcelains. Plainsman code G2934.
A dolomite silky matte for cone 6. It fires translucent rather than completely transparent (because it is a matte). If you want pure white, add Zircopax (start with 5%, but keep it at a minimum to minimize cutlery marking).
G2934 Cone 6 Matte base (upper left sample) with various stain additions. A porcelain body has been used.
Almost certainly, the degree of matteness will not be quite right for you (many find it a little too matte).
G2934 matte is an excellent color base and works particularly well with inclusion stains. However, each different color you create using this base will likely require fine-tuning the degree of matteness. It is already quite matte, to shine it up slightly by blending in some of either of the clear glossy bases Whiteware G2926B or Stoneware G2916F (click here to see an example).
Screening: We have not ball milled this product, thus it may contain some oversize particles from the constituent materials. We advise sieving the glaze slurry to at least 80 mesh.
We developed this recipe and sell it premixed, but the recipe is not a secret. Detailed information about it is available at the Digitalfire Reference Library, click here to go there.
Adding the Stains and Opacifiers: Simply multiply the weight of the amount of powder you want to use and divide by 100. For example, if you have 2000 grams of glaze powder and want to add 6% stain: 2000*6/100=120 grams of stain. Or, 10% zircopax: 2000*10/100=200 grams of zircopax. The percentages of stain shown are suggestions. For some colors you may need to use more, others less (your fired results will demonstrate if the glaze is too dark or too light for your liking). If you are glazing a dark-burning body, consider applying a white engobe to areas where you want bright colors. For functional surfaces that you want to be white, consider applying a white engobe to the inside of the ware (at the leather hard stage) and using a transparent, this will give a much cleaner and more homogeneous surface than (white glazes do not cover well over a dark bodyies). If you are new to the use of engobes and fire cone 6, consider starting with this one.
12% yellow and 8% orange stains in G2934 base recipe. The silky surface of these is outstanding!
