These revolutionary hollow core CoreLite kiln shelves are LIGHTER and FLATTER than standard shelves and rated to Cone 10 by the manufacturer. You may not want to fire them as high as Cone 10 for optimal results (i.e. warp resistance). Their unique design reduces the weight and thermal mass for less back strain and lower firing costs. The combination of their ‘I-beam’ structure and a higher mullite composition create a shelf that is crack and sag resistant. In addition, each shelf is ground top and bottom for perfect flatness. As with all kiln shelves, 3-posting, rotating and moderate firing rates are recommended. (Not recommended for Raku, Salt or Wood Firing.)
*Important Note* Always temper new shelves before use in a bisque or glaze firing. To temper stack the kiln with all your new shelves to be fired alone (no clay wares or kiln wash) and fire to cone 6. If you do not temper your shelves you risk cracking or even fracturing the shelves during the firing. *shelves that have cracked due to user error/ lack of tempering can not be returned or exchanged.
All kilns have furniture kits available that have been configured by the manufacturer to suit most buyers needs.
