Abstract: A refractory lattice for use in cooking above a flame source and below a cooking zone includes:(a) a series of integrally interconnected refractory bodies forming a generally horizontally extending lattice,(b) metallic members projecting lengthwise through multiple of said bodies and confined within the lattice to reinforce same,(c) whereby the bodies will be heated by flames rising from said source to radiate heat upwardly to the cooking zone, and the metallic members will not be directly exposed to said flames.The bodies are typically arranged in regular pattern over the lattice, and openings are formed at regular intervals over the lattice, and between the bodies.
