Kiln Shelves Sillimanite (Alumina) 457 x 610 x 25mm CCG

Although the manufacturer states these shelves will fire to a higher temperature,

We do not recommend the 13mm shelves be fired above 1220°C. Under careful oxidising conditions, the heavier 19mm shelves will withstand temperatures of 1300°C.

                 We would warn against using these shelves in heavy reduction atmospheres.
