CoreLite

CoreLite kiln shelves are a unique extruded hollow core shelf. They are a ‘clay’ shelf composed of a Mullite/Cordierite mix that is rated to Cone 10 by the manufacturer. The shelves are extruded with hollow channels inside making them significantly lighter than standard solid shelves. An ‘I-Beam’ structure between the channels gives CoreLites extra strength making them warp and crack resistant. The top and bottom of each shelf is ground to a perfect smooth, flat surface. Suitable for Oxidation and Reduction* in both gas and electric kilns. CoreLites are available in many sizes to accommodate both top and front-loading kilns.

Reduced weight: Their hollow core structure makes them significantly lighter, reducing the strain on your back when loading and unloading the kiln. 
Improved durability: They are less prone to warping and cracking compared to solid shelves.    
Faster heating and cooling: The hollow core design allows for quicker temperature changes, potentially leading to energy savings.   
Cost-effective: While the initial cost might be slightly higher, the long-term benefits in terms of durability and energy savings can offset this.
