Item #: CH-CC1
Copper carbonate (CuCO3) is a green powder that is used primarily as a glaze or slip colorant. Depending on firing conditions and glaze formulation it has the potential to produce shades of green, turquoise or reds (reds usually occur in reduction firings). Copper carbonate can also be applied by brushwork as a wash on bisqueware.
Suggested concentrations of copper in the preparation of slips and glazes are as follows:
In slips: 2 - 8%
In glazes: < 5%
If concentrations above 5% are used, glazes often change to a metallic pewter.
IMPORTANT INFORMATION: Copper should not be used as a component in soluble glazes that will come in contact with food or drink, as it is likely to leach.
In its powdered form, copper carbonate is harmful if swallowed, and may cause skin and eye irritation upon contact. Please use protective coverings when handling this chemical.
