Marilee’s Lava Glaze	Cone 6, oxidation or reduction
Glaze Material
Whiting	23.91%
Custer Feldspar	49.73%
Edgar Plastic Kaolin (EPK)	13.18%
Silica (Flint)	13.18%
Total:	100.00%
Add:
Titanium Dioxide	11.29%
Silicon Carbide	3.4%

A very rough glaze; not intended for food surfaces. Fine silicon carbide seems to work best. For a gray to black variation, add 7% Mason stain 6600.

What was the answer to this question from Kirk??? BTW – is this going to coat the kiln with little black dots of glaze as the CO2 off gasses? Do you need to use a Sagr?

Can anyone clarify the percentage of Silicon Carbide? I’ve seen this in three other locations and they list it as .34% vs 34% I’m not a mathematician but it seems like a big difference. Thx
