Rokite stone cooking decks are designed for even heat transfer and moisture absorption, which means crispier crusts when baking. Rockite is an anti-stain and corrosion resistant impregnation and sealer for protecting stone. It seals the surface to resist staining and corrosion from a range of oils, grease, fats, lubricants, sugars, lactic acids, soft drinks, mildly acidic or caustic solutions.
