Coyote Slow Cool Glaze, Mars Red Iron
- Additional information
The Constellation series of cone 5-6 glazes are designed to shine in all kinds of firings. These glazes are unmatched for versatility, changing dramatically depending on how they are used. Thickness, firing temperature, and especially cooling speed can affect these glazes in marvelous ways.
Slow cooling effectively lengthens the period of firing during which most crystals develop. Depending on the composition of the glaze, this will usually produce either large visible crystals, or a matted surface of micro-crystals.
To slow cool a glaze, you must be firing in a kiln with a digital controller. Coyote’s schedule is below:
100/hr to 220
350/hr to 2000
150/hr to 2200 hold for 15 minutes
