Heat treated steel , stainless steel, clear protective sealant. This picture is all metal. No paint is used. The color is attained with heat and different metals.This is a beautiful, hand cut, hand ground, heat treated, three dimensional piece I made in 2009. As the light changes in a room so does the feel of this picture. It truly stops people when they see it. Although it is large and heavy it will hang on sheetrock with special heavy duty hangers available at the hardware store.
