Here is a small bowl I did out of the Cassius Basaltic Clay.
The liner glaze is a PB (Plastic Bitrox) Liner. This glaze works very well with this clay because the PB Liner is able to be fired with a range of cone 4 to cone 14. So if the cassius Basaltic clay still has gasses to be released, even after a longer bisque period, the PB Liner stays in a liquid / molten state for a longer time, giving the gasses from the clay time to escape without creating cratering in the glazing.
The PB Liner recipe with Percentage by Weight:
Colemanite 50%
Plastic Bitrox 50%
Zircopax 10%
To fill a 5 gallon bucket only 3 quarters full you would use
Colemanite 3000 grams
Plastic Bitrox 3000 grams
Zircopax 600 grams

Thanks for this glaze recipe, can't wait to try it, but that combo of the white slip with clear over the top is sure appealing.
