Mayco Raku Glazes
Mayco Raku glazes are designed to develop beautiful metallic lusters and crackle patterns when fired using the raku firing processes.
Glazes designed for the mysterious raku process using combustibles and varying firing methods to produce unique finishes. There are several methods and many nuances to firing Mayco Raku glazes. 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.
Mayco Raku glazes are CL (Health Caution) with the exception of RK-103 White Crackle, which is AP Non-Toxic. Raku glazes are not recommended for dinnerware due to the durability of the fired glaze. Some glazes, regardless of surface texture or porosity of underlying clay body, will be designated as not suitable for dinnerware as the fired glaze surface is not durable and can be impacted by contact with food or liquids. While it may not be harmful, it is certainly not desirable. Recommended for ornamental use only.
