Mayco Raku glazes are designed to develop beautiful metallic lusters and crackle patterns when fired according to raku firing processes. There are several methods and many nuances to raku firing - for our purposes here we define raku firing broadly as the processes of firing an earthenware body and glaze in a kiln, removing the ware from the kiln after it has reached proper temperature, placing it in a container of combustible material and enclosing the container to reduce the oxygen in the container.
Shake for 5-6 seconds before use. Stir well. Apply 2 coats to cone 04 bisque (1940°F, 1060°C). Do not glaze bottom of ware. Allow to dry thoroughly.
