Lead mining colors and underground art inspiration converge in the North Pennines, where an abandoned mine reveals an explosion of color and natural formations. This unique environment, rich in mineral stains and cave pearls, captivates artists and potters, offering a profound connection between geology and creativity.
The Hidden Entrance to an Underground World
Finding the entrance to the old lead mine is no easy feat. Hidden by downy willow, ferns, and field rush, only a trickle of rusty water hints at the opening. Pushing through the scrub, visitors enter a long adit lit by helmet torches, its arched stonework streaked with minerals. The precision of the masonry and the smell of damp earth and wood create an atmosphere of historical wonder.

Led by miners from nearby Nenthead, a group of potters and artists explores this subterranean realm, seeking inspiration for an exhibition on lead mining. The experience is transformative, as the mine’s natural palette—vivid orange from iron, milky white waterfalls, raspberry-pink from cobalt, and sulphurous yellows—provides a stunning visual feast.
Natural Formations: Soda Straws and Cave Pearls
The roof of the mine gleams with stubby stalactites known as soda straws. These hollow tubes form as mineral-saturated water deposits calcium carbonate around the tube’s rims. Over time, this process encases organic matter, transforming it into stone-like structures. A tangle of what appears to be roots is actually calcified bootlace fungus, once thriving on decaying timber.
Among the most captivating formations are cave pearls, shiny ivory pebbles nestled in cupped depressions. Formed drip by drip, calcium encloses tiny grains of sand, and the vibration of each drop keeps them from adhering. This delicate process creates pearls that are both simple and profound, offering a metaphor for patience and artistry.

Artistic Impact and Exhibition Inspiration
For the visiting artists, the mine is more than a geological site; it is a muse. The mineral colors and textures translate directly into their work, from drawings of cave pearls to pottery glazes mimicking the mine’s palette. The experience culminates in an exhibition that celebrates the intersection of industrial history and natural beauty.
As the group wades through flooded sumps and past worked-out flats, they emerge wet but elated, carrying images of the underground world. At home, drawings reveal new details—shallow folds, converging channels, and the purity of color—that fuel their creative process.
Comparison of Mineral Formations
| Formation | Composition | Color | Formation Process |
|---|---|---|---|
| Soda Straws | Calcium carbonate | White to translucent | Dripstone deposition |
| Cave Pearls | Calcium carbonate | Ivory to brown | Concretion around sand grains |
| Flowstone | Calcite | Orange, yellow, red | Water film deposition |
