Description: 

Stibnite (antimony sulphide) is the main ore mineral of the metal antimony.

Small amounts of antimony minerals were found in many Cornish mines but only a few were worked for antimony. Fewer still tried to produce it as their single main product.  Most of these mines were in the north of the county. This specimen was acquired by the Royal Institution of Cornwall before 1881. It is from Wheal Boys (also called Trewetha Mine), an old antimony mine in the parish of St Endellion, which was worked in the late 18th century.

Antimony is most useful when alloyed with other metals, increasing their strength and durability. It was added to some types of pewter (an alloy of tin) from the late 17th century onwards.
