13" Round Kiln Shelf 5/8" Thick for Pottery Firing

What size kiln shelf do I need? This 13-inch round, 5/8" thick shelf fits most small to medium electric kilns. It provides a stable, level surface for pottery, ceramics, glass fusing, and metal clay. The full round shape maximizes usable floor space, letting you fire more pieces per load. Can it handle high firing temperatures? Yes. Made from cordierite-mullite refractory material, this shelf is rated to 2280°F (Cone 10) — suitable for stoneware, porcelain, and glass slumping. It resists thermal shock and maintains structural integrity through repeated heating and cooling cycles without stress fractures. Will it warp or crack over time? No — the 5/8" thickness provides exceptional stability and warp resistance under normal firing conditions. Unlike thinner shelves, it stays flat and true through repeated firings, protecting your pottery and glaze from uneven surfaces that can ruin finished pieces. Is it good for both pottery and glass fusing? Absolutely. This versatile shelf works for ceramics, glass fusing, metal clay, and enamel. The smooth surface helps prevent glaze drips and glass sticking, reducing shelf wash needs and speeding up cleanup between firings. How should I care for it? For best results, apply a thin coat of kiln wash before each use to protect the surface and extend shelf life. A durable, long-lasting addition to your kiln furniture collection, it delivers professional results every firing.
