13″ Round x 5/16″ ADVANCER® Kiln Shelf


13″ Round for small electric kilns.
4 lb. Fine grained, nitride-bonded silicon carbide. 2600ºF max.

Available on backorder


Slow and medium firing cycles are recommended for most full and half Advancer Shelves for top loading electric kilns. We do not recommend exceeding 300F per hour from ambient temperature up to 1000F. We do not recommend exceeding 300F per hour during cooling. Force cooling is not recommended.

ADVANCER® for Top Loading Electric Kilns

Lighter, stronger and more versatile than any other shelf.
Save kiln space. Save energy. Save money.

Imitated but never equaled, ADVANCER® kiln shelves are thin, lightweight kiln shelves made from an advanced fine grained, nitride-bonded silicon carbide composition. ADVANCER kiln shelves are 19 times stronger, and weigh 50% less than conventional silicon carbide shelves or 1” thick cordierite shelves.

Kilnshelf’s Exclusive Multi-Sided Plates. ADVANCER® kiln shelves are available in 8, 10 and 12-sided shapes to fit most top loading electric kilns. They are the only silicon carbide kiln shelves tested and recommended for use in resistance coil element kilns.

Made flat to stay flat so there’s no warping even after many firings under heavy loads. Advanced nitride-bonded silicon carbide (NSiC) is distinguished from conventional nitride-bonded silicon carbide in that it is significantly stronger, thinner and much more resistant to oxidation; suitable for temperatures up to 2600°F!

Part of our exclusive LO-MASS® product line. Low mass and high thermal conductivity result in shorter firing cycles helping potters to save energy, improve productivity and reduce overall firing costs. Also, at only 5/16” thick, for every 5 layers of shelves you save 3-3/8” of stacking height compared to conventional 1″ shelves. That can add another shelf layer for every firing!
