Description
A soft, white mineral composed of magnesium calcium carbonate. The mineral huntite was first described by Faust in 1953 and its use as a pigment by ancient Egyptians was identified by Riederer in 1974 (Eastaugh et al 2004).
Physical and Chemical Properties
Microscopically similar to calcite. Moderate birefringence with strong interference colors.
| Composition | Mg3Ca(CO3)4 |
