Only iron base surface, No chemical pollution while cooking, safe temperature to 1000F degree not be damaged even dry heat. The uncoated iron surface be 3 times harder than the steel one, which be safe for metal spatula.
●Pure iron, no chemical coating
●Thin wall, 30%-50% light weight
●Rust resistant
●Scratch resistant
●Metal spatula safe
