Bissoe Arsenic Factory (United Kingdom)


In the early 19th century Cornwall pioneered the production of arsenic as a by-product of tin and copper mining.
The first commercial British arsenic was produced at Perran-ar-Worthal in 1812, followed by a works at
Bissoe in the Carnon Valley. Its main market was the expanding Lancashire cotton industry which used arsenic in pigments and dyes.

1882 The Cornwall Arsenic Co's Works at Bissoe produced 580 tons of refined arsenic. For many years 300 tons of arsenic was exported annually, the bulk to Australia and New Zealand for sheep-dip, and some to Norway for glass making. A quantity was sent to South America for troll weevil.

Today, near to Bissoe Valley Nature Reserve you can see a chimney and other remains of the Point Mills Arsenic Refinery. The British Arsenic Company (later the Cornwall Arsenic Company) operated these works for a century, ending with the outbreak of World War 2. The arsenic was of a particularly high quality.

Bissoe Arsenic Works is still standing although the square chimney shows damage due to a lightening strike some years ago. The Germans bombed the Arsenic works in World War II, but the arsenic works had been closed for many years at that time.
