MALACHITE is a copper carbonate hydroxide mineral typically found as stalactites and botryoidal coatings on the surfaces of underground cavities.
When this material is cut into slabs and pieces, the cut surfaces often exhibit banding and eyes that are similar to agate.
Malachite is found worldwide and archaeological evidence indicates that the mineral has been mined and smelted to obtain copper in Israel and Britain for over 3,000 years. In addition, its rich green color that does not fade over time or when exposed to light, along with its ability to be easily ground to a powder, made malachite a preferred pigment and coloring agent for thousands of years.
The technique used to make faux Malachite was borrowed from ancient Egyptian jewelry and consists of combining layers of various hues of colored porcelain paste to create a banded effect.
