Sillimanite Kiln Shelves - Although the manufacturer states these shelves will fire to a higher temperature, we do not recommend the 13mm shelves be fired above 1220ºC.
Under careful oxidising conditions, the heavier 19mm shelves will withstand temperatures of 1300ºC.
We would warn against using these shelves in heavy reduction atmospheres.
All new refractories need to be dried before use, we suggest drying for at least 24 hours, with a temperature not exceeding 110ºC.
Indents available on all non stock sizes – please email CCG with the size and thickness required.
