Square Cordierite Kiln Shelves. For Cone 10 firing, we recommend shelves that are at least 1" thick. Otherwise only fire the 5/8" thick shelves up to Cone 8. .
Note: There are additional packing charges for shelves shipped by standard carriers. For orders larger than 12 shelves, we mayl contact you, and adjust the shipping charges to that of an LTL carrier. Shelves are extremely fragile to ship UPS or mail, and require a LOT more packing, and additional insurance to ensure safe arrival
