Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Copper is an essential oil distiller for medicinal purposes, e.g., to produce remedies. Copper is best suited for its antimicrobial effects. It naturally removes harmful fungi, germs, and bacteria that are not supposed to remain in the distillate. That's why copper has a good standing in the production of perfumes, hydrosols, and essential oils.
