Ans: Granite-coated utensils usually have a stainless steel core and are coated with glass on top. Porcelain enamel is fused into it at 2000 F which creates a non-sticky glass finished surface that is non-porous. Technological advancements have resulted in lighter granite coatings. Make sure that these are free from PTFE and PFOA to be safe. Coming to Teflon coatings, even though they have a similar look, generally chemicals are used which are unsafe.
