Mining in Cornwall

Tin is a relatively rare metal, found in two parts per million (as opposed to copper's 70 parts per million and the abundant iron at 50,000 parts per million). It was very useful, however, for its workability and especially for the making of alloys, so any source was a valuable find. Large deposits were found in the Far East, Iberian Peninsula, and souther France, but we will confine this post to talking about Cornwall.

The earliest evidence shows that tin was being mined in at least 2150BCE, the early Bronze Age. Copper was also found there, along with some arsenic, lead, silver, and zinc, but tin mining has been the most consistent use of the mines for millennia. When a small amount of tin is added to copper, the resulting bronze is much harder than either and more useful. This made tin a more useful commodity than just using tin on its own, and a tin trade with the Mediterranean started long before even the Roman Empire. Herodotus mentions an area called the Cassiterides, the "tin islands," and Cornwall is thought to be the likeliest spot.

One of the oldest mines in Cornwall is the Ding Dong mine (the name may refer to the "head of the lode"). The picture above is a shaft at the Ding Dong. A local legend claims that the mine was visited by Joseph of Arimathea, tin trader and uncle to Jesus, who visited the mine with the young Jesus; not his only trip to Britain, since he later founded Glastonbury Abbey, etc. (There is, of course, no evidence, but that's what legends are.)

Curiously, Domesday Book doesn't mention Cornwall tin, but Henry II acknowledged it when he granted to Dartmoor, another mining location,

all the diggers and buyers of black tin, and all the smelters of tin, and traders of tin in the first smelting shall have the just and ancient customs and liberties established in Devon and Cornwall.

This indicates that Cornwall mining was "ancient" as of Henry's reign. Henry's son John granted a charter for the miners' rights, establishing stannaries that allowed the tin-mining community to administer its own laws, etc.

The mines produced an enormous amount: 650 tons in 1337, falling to "only" 250 tons during the Black Death, but rising to 800 tons by 1400.

Demand for tin decreased in the 20th century. Increased recycling efforts, as well as the use of aluminum for containers and the development of protective polymer lacquers to coat food containers hastened the closing of tin mines as unprofitable. One of the last tin mines in Cornwall to close was the South Crofty mine in 1998, Europe's last tin mine.

Fear not for Cornwall mining, however! The 21st century is finding reasons to re-open defunct Cornish mines for a substance as important to our time as tin was to the Bronze Age: lithium, an element vital to our battery-operated world. (Here is a link to National Geographic article.)

Going back to the Middle Ages, however, I want to talk about another substance, made with tin, that was so associated with daily use in the Middle Ages that a 19th century revival of interest in the Middle Ages made this substance much in demand. Check back tomorrow and we'll learn more about the lovely, useful, and toxic pewter.

Glastonbury Abbey


Glastonbury Abbey in Somerset may be the best-known of English abbeys. Originally founded in 712 with the construction of a stone church, it has been rebuilt and expanded many times. One of the expansions was under Dunstan (mentioned here) when he reformed it, expelled all the monks he considered unfit, and instituted the Rule of St. Benedict. It became an important site: King Edmund I was buried there, and an important charter of King Cnut's was disseminated from there.

Legend claims that an abbey was founded there in the 1st centuryCE by Joseph of Arimathea, the New Testament figure who provided the tomb for Jesus. This legend was described by Robert de Boron, a French poet of the late 12th century. His claim was that Joseph brought to Glastonbury 12 disciples as well as the Holy Grail containing drops of Jesus' blood, collected as he suffered on the cross.

For these and other reasons, Glastonbury became prominent as a pilgrimage site and a political power. A fire in 1184 destroyed the monastic buildings. Not wanting for money, reconstruction began right away, but the building of a large church and many buildings takes time. Pilgrimages—and the donations they bring—declined. In 1191, however, a discovery took place during excavation that would bring attention to Glastonbury once again, and shed light on an age-old legend.

But that's a story for tomorrow.
