Lead mine colors in the North Pennines offer a breathtaking underground palette that has inspired a group of potters and artists. This abandoned mine, hidden by downy willow and ferns, reveals an explosion of color—from vivid orange iron stains to raspberry-ripple pink cobalt traces—making it a unique muse for creative work.
Exploring the Hidden Entrance and Adit
Our journey began with a search for the entrance, so concealed by vegetation that only a trickle of rusty water hinted at the opening. Pushing through scrub, we entered a long adit lit by helmet torches, its arched stonework streaked with minerals. The precision of the masonry and the damp earthy smells set the stage for an unforgettable underground experience.

Led by two miners from nearby Nenthead mines, our small group of artists and potters marveled at the geological wonders. The adit’s walls displayed a spectrum of colors: milky solidified waterfalls, elephant-hide greys, and sulphurous yellows, each telling a story of mineral deposition over centuries.
The Astonishing Mineral Palette
The colors were truly astonishing. Iron stained the rock vivid orange, while cobalt added a pink hue reminiscent of raspberry ripple. These natural pigments are not just visually striking but also hold scientific significance, indicating the presence of various metals and minerals.
We observed stubby stalactites known as soda straws, formed by drops of water depositing calcium carbonate. The mineral-saturated water had encased and transformed organic matter, including calcified bootlace fungus that once grew on decaying timber. This process of mineralization creates a unique fusion of biology and geology.

Cave Pearls: Nature’s Artistry
One of the most entrancing sights was the cave pearls—shiny ivory pebbles nestled in cupped formations. Formed drip by drip, calcium encloses a tiny grain of sand, with vibrations preventing adhesion. These pearls are a testament to the slow, patient work of nature, and they became the central image for my drawings.
As we navigated past flooded sumps and worked-out flats where lead was extracted, we encountered a line of water spouts pouring through the side wall. Joining the stream that ran down the adit, we emerged wet but elated, our senses filled with the underground’s beauty.
Artistic Inspiration and Exhibition
This expedition was part of a project leading to an exhibition inspired by lead mining in the North Pennines. The colors and formations we saw are directly influencing our work, from pottery glazes to paintings. The cave pearls, in particular, offer a motif of concentric layers and subtle shading.
Back home, I made detailed drawings of the cave pearls, and my photos revealed new details: shallow folds and channels converging on the bowl, and the purity of color. These observations will translate into ceramic pieces that capture the essence of this hidden world.
Comparison of Mineral Stains
| Mineral | Color | Source |
|---|---|---|
| Iron | Vivid orange | Oxidation of iron compounds |
| Cobalt | Raspberry-ripple pink | Trace amounts of cobalt |
| Sulphur | Sulphurous yellow | Sulphur deposits |
| Calcium carbonate | Milky white | Stalactites and cave pearls |
