Our Ceramic Grill Tiles are the perfect addition for grilling enthusiasts and casual chefs alike. When grilling chicken, sausage, or similar fare on a gas barbecue, flare-ups can blacken even the most carefully attended food. The solution is in our special cordierite ceramic that distributes heat uniformly, yet maximizes heat transfer. Our tiles are long-lasting and can be cleaned simply by flipping and burning the residue right off. Lava rocks and other ceramic-based briquettes eventually become old and saturated with drippings, requiring regular replacements. The 2"x3 1/2" tiles come in packages of 30 (210 sq.in.) or 45 (315 sq.in.). NEW AND IMPROVED PACKAGING - no broken tiles guaranteed! If they do arrive damaged at all, please contact customer service and we will send replacement tiles at no charge.
