A white base glaze with all the advantages of Ravenscrag Slip base GR6-A. It is not drab-looking like a porcelain toilet, but is vibrant and interesting on stoneware bodies. It breaks to clear on the edges of contours and has variegation. It works well with added stains, the variegation of this base (adding a little titanium dioxide) makes the color much more interesting.
Adjust the amount of zircopax as needed to adjust the degree of whiteness.
Because it contains an opacifier, this can be a base for the addition of colorants to produce pastel colors (adding them to the transparent base will produce deep brilliant colors). We recommend stains rather than metal oxides.
For mixing instructions please see the master recipe, GR6-A.
Right: Ravenscrag GR6-A transparent base glaze. Left: It has been opacified (turned opaque) by adding 10% Zircopax. This opacification mechanism can be transplanted into almost any transparent glaze. It can also be employed in colored transparents, it will convert their coloration to a pastel shade, lightening it. Zircon works well in oxidation and reduction. Tin oxide is another opacifier, it is much more expensive and only works in oxidation firing.
The body is Plainsman M340. This is a good alternative to trying to get a chrome-tin pink or maroon working.
0.5% fine granular illmenite added to Ravenscrag cone 6 clear glossy white base glaze.
