Copper Carbonate

Formula: CuCO3
Alternate Names: Synthetic Malachite, CuCO3

Enter the formula and formula weight directly into the Insight MDT dialog (since it records materials as formulas).
Enter the analysis into an Insight recipe and enter the LOI using Override Calculated LOI (in the Calc menu). It will calculate the formula.
DENS - Density (Specific Gravity) 3.70
MLPT - Melting Point (MP) 500C D
TGA - TGA See accompanying curve image

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.
