G1916Q Transparent Base Glaze
G1916Q + 2% iron oxide mixed as a dipping glaze and applied on L215. These were fired at cone 03, 05 using the 04DSDH schedule. The cone 03 version has a deeper variegated color and the body is stronger, but there are tiny dimples on the surface, almost too small to see (because the glaze firing is significantly higher than bisque, decomposition in the body is generating bubbles). The cone 05 version, right, is like glass.
If the specific gravity is around 1.43 and it is gelled enough it applies very evenly with little dripping. Ware needs to be absorbent. If your ware is thin it might be necessary to glaze the inside and outside in separate operations (with drying time in between).
This is not available as a premixed product. But you can mix (and adjust) it yourself. For our lab information on the recipes, how to mix and use them click here. You can color this using stains or make it white by adding Zircopax.
Low fire glazes are much more difficult to match to the body, crazing and shivering are thus much more common than at higher temperatures. It intended that you adjust the 1916Q recipe to fit your clay body.
G1916Q on L215, L212, L210, L213, Buffstone at cone 03. All exited from the kiln without crazing. The L215, L213, L210 and L212 samples subsequently survived a 300F/Icewater test without crazing, but the Buffstone did not. The L213 would not likely survive a cold-to-hot test without shivering.
