Kiln wash is a protective coating applied to the top surface of the shelves.  This coating provides a layer of protection against glaze from adhering to the kiln shelf. One proper application of Mayco Kiln Wash will remain effective through multiple firings, increasing the working life of the kiln shelf.

Shake or stir well. Thin with water if needed. Prior to applying, wipe the kiln shelf with a damp sponge to remove dust. Brush two to three uniform coats to kiln shelf on one side, allowing Kiln Wash to semi-dry between coats. Not recommend for use with conventionally formulated kiln washes.  Remove conventionally formulated kiln washes prior to application of Mayco Kiln Wash.

• Mayco Kiln Wash offers superior performance for oxidation, reduction, and specialty kiln firings; ranging from cone 018 to cone 13 temperatures.
• Mayco Kiln Wash is easy to apply and flows smoothly over the kiln shelf. It will not crack or peel when properly applied according to directions.
• Fire shelves with bone-dry greenware in a bisque firing to mature the kiln wash. Apply it to other kiln furniture and stilts to avoid glaze fusing to the surface.
• Can be used on posts for wood, soda and salt firings.
