Cone 11 High Alumina Shelves
All shelves that are 15” in diameter and above are made of a high alumina cordierite body that holds up to Cone 11 firing with little warpage. This is particularly important for these larger shelves.
L&L sells the highest grade posts on the market. They are very straight (even in lengths up to 12” long), precision cut for squareness and are strong without being excessively thick.
