Shelf Kits

FINALLY! The ever elusive shelf kits you've been searching for! Introducing our wide selection of Mullite kiln shelf kits! 

Heat Resistance: Mullite has high heat resistance, suitable for a wide range of firing temperatures, including high fire (Cone 8-10 and beyond).

Strength and Durability: Known for their strength and resistance to warping under load at high temperatures.

Thermal Shock Resistance: High-alumina Mullite shelves exhibit lower thermal expansion, leading to better thermal shock resistance.  

Weight: Denser and heavier than other shelves of the same size.

Whether you're firing ceramics, pottery, glass, metal clays, or heat treating, our shelf kits ensure optimal performance and convenience. Suitable for both electric and gas kilns.

Need to replace a worn-out or broken shelf? We've got you covered! Can't find what you're looking for? Contact us, and we'll point you in the right direction.
