Matte Cone 6 Glaze

Description

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.

Process Properties

Almost certainly, the degree of matteness will not be quite right for you. Fine-tune it.

Click here to see an example of how to blend in a glossy base to fine-tune the degree of matteness.

If this is too matte blend in some of either of the clear glossy bases (G2926B, G2916F). 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 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 may contain some oversize particles from the constituent materials. We advise sieving the glaze slurry to at least 80 mesh.

Recipe

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. For more detailed information at the Digitalfire Reference Library (e.g. the recipe, mixing your own, more pictures) click here. The mechanism of the recipe is explained, this may empower you to adjust in ways we have not tried.

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.
