Minerals - Geology Gallery , Part 2
Caption - Image shows a display case of mineral specimens.
As we continue to walk around the gallery we walk past a spar box displayed on the wall.
The folk art tradition of making spar boxes (spar is short for fluorspar) flourished in the iron mining districts of West Cumbria and among the lead miners of the North Pennines.
This box was probably made by an iron miner in West Cumbria and contains crystals of quartz, hematite (sphalerite), and 'kidney ore'. Although this one is quite simple, some were made very elaborate.

Wire-splicing tools from the Scordale mines, Eden valley
The image below shows hand-tools used to set up and repair the multi-strand wires ropes of an aerial rope-way in Scordale. This was used to transport ores downhill to the smelt mill.
Hilton Smelt Mill, Scordale, c. 1910
Galloway ponies had once carried ores down from the mines to the Mill. The steam traction engine seen here was a more efficient source of power. By this time the Mill was being used for crushing ores of barytes. From an photograph belonging to Mrs D Hinchclife, 1989
Miners at entrance to the Scordale mines
Mining in Scordale has a long history. The mines were worked for lead by the London Lead Company in the nineteenth century, and later for witherite and barytes. The miners pictured here in about 1940 are (from left to right): Jack Anderson, Tom Tinkler, Tom Anderson. From a photograph belonging to Mrs D Hinchclife, 1989
Caldbeck and North Pennine minerals
The North Pennines and the Calbeck Fells are both famous for their richness in minerals. They have been mined for centuries, for copper, lead and zinc, as well as rarer elements such as silver and tungsten. Quartz, calcite, dolomite and fluorite are the most associated minerals. The beauty and rarity of many specimens makes them attractive to collectors.
