Cavers exploring the mining tunnels at Alderley Edge in Cheshire have discovered a cobalt mine preserved exactly as it was when it was abandoned in around 1810. Members of the Derbyshire Caving Club, who have a special lease from the National Trust to explore the Alderley Edge mines, found the historic cobalt mine last fall. The mine was in a state of suspended animation, replete with the miners’ personal objects, mining gear and graffiti they’d left on the walls. They have been exploring the labyrinthine tunnel network since then.
Leather shoes, clay pipes, a metal button from a jacket, along with inscriptions written in candle soot, and mine machinery, were among the objects that were found.
Also uncovered was a clay bowl that had been buried in a wall, a practice that may have been followed by superstitious miners as an offering of thanks for a good vein of mineral. Other discoveries include clearly defined fingerprints in clay used to hold candles, and the imprint of corduroy from a worker’s clothing where he leaned against a wall.
Among the larger abandoned items was a windlass, a piece of equipment used to shift large weights or quantities of raw materials. This is the first time such a piece has been uncovered at Alderley Edge. […]
Ed [Coghlan of the Derbyshire Caving Club] continued: “One of the objects which we had not unearthed in this area before, was the windlass. This was an important piece of mining equipment which we would have expected the workers to have taken with them for use at another mine. It does suggest they were told without much warning to collect their tools and move on, which is not surprising once the cobalt was exhausted, since each day there was a day paying wages.”
Cobalt mining had a very brief history at Alderley Edge. It began during the Napoleonic Wars when Continental sources of cobalt to make blue glass and pottery glaze dried up. Sir John Stanley, 7th Baronet of Alderley Hall, leased cobalt extraction rights to the Alderley Edge mines. The bottom dropped out of the English cobalt market after Napoleon’s final defeat in 1815, and the Alderley Edge cobalt mines were closed by 1817. The discovery of this mine frozen in time sheds new light on the brief history of cobalt extraction in Alderley Edge’s 4,000-year history of being mined.
The objects in the mine have been photographed and documented in situ, but they have not been and will not be removed. They will remain in the environment that has conserved them for 210 years. The National Trust has created a virtual 3D fly-through of the mine created with data from laser scanning, submarine ROV and photogrammetry technology. Explore it below:

The clay bowl the in wall might have been a sort of offeratory to mine sprites. These were were a type of brownie or gnome who were believed to live in mines. The little people might snuff out candles or steal tools if not placated with a corner of the miners’ lunch pasties. If the creatures were kept happy, they might warn the miners of danger such as cave-ins by tapping on the rocks, thus they were called “Tommyknockers”.
These beliefs were common in Cornwall, Devon and Wales, but likely spread to other areas of Britain, such as Chester. Cornish miners even brought these beliefs to America in the 19th century.

On those tommyknockers or leprechauns I cannot say a lot. There is a role model, however, for “sprites” in glass production and mining also reflected in the “Seven Dwarfs” –at least some of them apparently came from Italy.
“Walen or Venediger (also Wahlen, Venezianer, Venetianer and similar spellings) are traditionally foreign ore and mineral seekers. Due to their foreign jabber, attire, physical appearance and incomprehensible actions in the mountains, they have inspired the creation of legends throughout Central Europe.
In the legends, magical properties were also attributed to them. They appear there as magical and ghostly foreign beings. In addition, they were attributed the authorship of the so-called walen books: alleged directions to hidden treasures and rich deposits of ore.”
