Malachite

Description

Malachite is a copper carbonate hydroxide mineral characterized by the chemical composition Cu2CO3(OH)2. This opaque material typically displays distinct green banding and adheres to a monoclinic crystal system. Structurally, it commonly manifests as botryoidal, fibrous, or stalagmitic aggregates, often precipitating in underground environments influenced by hydrothermal fluids and water tables. While distinct acicular or slender prismatic crystals are infrequent, the mineral occasionally forms pseudomorphs following the habit of azurite. Within the field of ceramics, malachite serves as a source of copper, which is valued for its role as a colorant in glazes and decorative surface treatments.
