Marilee’s Lava Glaze Recipe, Cone 6, oxidation or reduction

by Rick Malmgren Read Comments (4)

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.

    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

    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?

    Is it really 70% Mason stain 6600 or 7%?
