High Alumina Kiln Shelves are similar to Cordierite shelves but with higher percentage of alumina increasing the shelves' temperature rating to cone 11. They can carry heavier load and are less susceptible to warping but still require flipping / rotating to avoid sagging. High Alumina shelves are denser compared to Cordierite and therefore more resistant to glaze drips but they still porous and require kiln wash and are not recommended for Salt, Raku or Wood firings. High-Alumina shelves are best used in electric or gas kilns.
High Alumina (Aluminum Oxide) ceramic products are among the strongest and hardest of all ceramic materials second only to diamond. They have a high dielectric strength with excellent electrical resistance attributes. Alumina ceramics has high thermal conductivity and high resistance to chemical and corrosion
