Formation & geological history
Synthetic material created through a reduction-melting process, originally pioneered in 17th-century Venice (Murano glass techniques).
Uses & applications
Primarily used in jewelry, beads, figurines, and as a decorative or metaphysical stone.
Geological facts
Despite its name, it is a human-made glass. Legend says it was discovered by accident when Italian monks spilled copper filings into a vat of molten glass.
