In order to get as much satin as possible out of this glaze, it’s best to fire your kiln DOWN. Crystals grow on the cooling cycle between 1900-1400 degrees. I use a final ramp in my firing program that allows for 100 degrees/hour from 1900-1400.

This glaze is to be used on pots with texture but no slip. My black iron oxide step (used with the pots covered in colored slips) isn’t necessary here. Just bisque the textured pots to cone 06 and use this glaze directly.
