Significant Temperatures
- 1026C: The black oxide crystalline sructure breaks down
- 1350C: The CuO melts
- 200C: Copper disassociates to CuO like this: CuCO3 -> CuO + CO2
- 500C: The carbonate decomposes to CuO + CO2

Notes
Conceptually, copper carbonate is CuCO3, however this form is not normally available in the market (copper carbonate basic is the article of commerce) so the powder should be viewed as a family of compounds.
This material is considered volatile during firing and thus can affect the color of other pieces in the firing. See Copper Carbonate Basic for more information.
