Pentireglaze mines, Cornwall

On the east side of the Camel estuary, 3 and a half miles north east of Padstow, Cornwall. Pentireglaze Mine – St Minver, lead and silver mine, Henry Fowell Stephens of Egloshayle, purser and manager (*CRO, STA/693c/145, 1846)

There were mines producing lead here for around 400 years, with the production finally stopping in 1857. The parish history records that for some years lead mines were worked at Pentireglaze, Polzeath, and Trebederick but without much success.

Cerussite (also known as Horn silver, Lead carbonate, White leadore) is a mineral consisting of lead carbonate (PbCO3), and an important ore of lead. The name is from the Latin cerussa, white lead. Cerussa nativa was mentioned by K. Gesner in 1565, and in 1832 F. S. Beudant applied the name cruse to the mineral, whilst the present form, cerussite, is due to W. Haidinger (1845). Popularnames in early use were lead-spar and white-lead-ore. Delicate acicular crystals of considerable length were found long ago in the PentireGlaze mine near St Minver in Cornwall . It is often found in considerable quantities, and contains as much as 77.5% of lead.
