We were experimenting lately with various metal finishes on metal range hoods to make them more rustic. We decided to overheat metal the range hood was made of and let it cool off. The outcome was interesting pattern made of variety of colors ranging from dark blue to black. Some areas of surface were left untreated. The rustic metal range hood on the image is what it turned out during the process. We believe it might be applicable for certain ultra modern kitchens with some rustic touch.
