Oxidized Aged Copper Sinks

The hand making process of the bowl is cut from virgin copper sheet, flame fired, formed as a bowl as shown then textured using primitive hand tools resulting in a durable beautiful bowl.

Virgin pure copper sheeting is utilized. Remove the tape. Draw required shapes to cut onto a copper sheet with pencil or a sharpie marker. Use snips (Large scissor). Apply heat to copper with a torch, it starts to change color, turning different shades of bright red, purple and blue. Copper changes colors because of surface oxidation. As it is heated, a layer of black copper oxide will form, thus changing its color. As the temperature increases, the oxide layer will get thicker. The copper needs to be softened in order to form it into bowls or any other shape. This process makes shaping the metal possible with hand tools and is called annealing.
