Copper glance, also known as chalcocite, is a mineral that belongs to the family of sulfide minerals. It is primarily composed of copper and sulfur, with the chemical formula Cu2S. Copper glance is well-known for its deep blue to black color and metallic luster, making it easily distinguishable from other minerals.
In terms of its physical properties, copper glance has a Mohs hardness of 2.5 to 3, indicating that it is relatively soft. Its specific gravity ranges from 5.5 to 5.8, making it denser than average rocks. The mineral often occurs in massive or granular forms, with occasional small crystals.
Copper glance is widely found and associated with copper ore deposits around the world. It forms as a secondary mineral in the oxidized zones of copper sulfide ore bodies and is often found alongside other copper minerals such as chalcopyrite and bornite. In terms of its use, copper glance is a significant source of copper as it contains a high percentage of the metal. It is commonly extracted through mining processes for copper production.
In addition to its economic importance, copper glance also has aesthetic and collectible value. Its dark color and metallic shine make it a popular mineral among collectors, especially those interested in copper minerals. Overall, copper glance is a valuable mineral that plays a crucial role in the production of copper while also being cherished for its beauty and rarity.

The word "copper glance" is a term used to refer to the mineral chalcocite, which is an important source of copper.
The term "copper" comes from the Old English word "coper" or "copor", which itself originated from the Latin word "cuprum". The Latin term "cuprum" is derived from the Ancient Greek word "kyprios", meaning "Cyprus", as Cyprus was a major source of copper in ancient times.
The word "glance" in this context is derived from the Middle English word "glansen", meaning "to shine or gleam". It is believed to have originated from the Old French word "glacer", which means "to glide" or "to slide". This meaning is perhaps related to the shiny appearance of chalcocite, which can resemble metallic copper.
