Cone 6 oxidation: Copper Ore is a highly mobile, reddish brown metallic glaze. A dark bronze field breaks with areas of darker coloring and flashes of brighter red metallic. The movement within this glaze produces striking visual textures.
Cone 10 reduction (second image): Finish flattens. Color turns to red/brown. Increased movement.
TIP: This glaze WILL move. Take care when using on vertical pieces – reduce glaze thickness towards the bottom third to minimize run-off.
