A PAIR OF BLUE JOHN AND FLUORSPAR CAMPANA VASES

The large crystalline structure of the contrasting rim-bands employed for these striking vases indicates that it was probably mined from the 'Winnats Five Vein', a sample of which is illustrated in, T.D. Ford, Derbyshire Blue John (Ashbourne, 2000, p. 35), Ford also discusses the quantities of plain fluorspar and 'Hatterel' discovered in the veins which were mined on the northern flank of Winnats Pass, Derbyshire, and it is from here that the lower sections of these vases were probably mined.
