Meet the world’s first impact-resistant baking stone. Unlike the bulk of traditional baking ceramics available, Relic’s super durable baking stones can withstand the abuse of everyday cooking. Rigorous testing confirms: the Primo and Eco stones can even withstand drops and falls from countertop heights. Just like the Relic Oven, they are also easy-to-clean, durable, and stain-resistant. No more crushed and cracked stones on the middle rack. Both the EcoStone and the PrimoStone are built to last a lifetime. The Relic EcoStone is made with 60% recycled and reclaimed materials and exceeds industry standards for heat and impact resistance. The Relic PrimoStone also uses recycled materials and is designed for extreme durability and fast heat up times.
