24" x 12" x 3/4" Hollow Core Kiln Shelf

Rectangular CoreLite Kiln Shelf, 24" x 12" x 3/4 "

This is a hollow-core, extruded kiln shelf made of Cordierite and Mullite. This refractory is resistant to high thermal shock and is suitable for firing temperatures up to Cone ^10, or 2381°. 

These kiln shelves are roughly 24% lighter, flatter, and stronger than solid mullite/cordierite style kiln shelves. For example a solid 12" x 24" x 3/4″ shelf weighs 20.75lbs while the same size Corelite shelf weighs 12.3lbs. Hollow Core Kiln Shelves typically see less warpage and are less likely to crack.
