Summary
Blue John (Derbyshire Spar) and Ashford Black Marble, a Blue John campana urn mounted on a Blue John and Ashford Black Marble base and plinth, British (Derbyshire), c.1760-1820.
Full description
Blue John is a rare semi-precious fluorite which crystalises in bands of purple, blue and yellow. Its distinctive colouring and light-reflecting qualities made it a highly-prized commodity in the late 18th and 19th centuries, especially as its only known source in the United Kingdom is Derbyshire. Mined from two caverns near Castleton and the now abandoned Old Tor Mine on Winnats Pass, one of the earliest recorded decorative uses of Blue John was at Kedleston Hall, where Robert Adam chose to inlay a panel of it in the State Bedchamber fireplace (c. 1768; NT 107960). Derby marble masons Richard Brown & Sons made the fireplace to Adam's designs, obtaining their Blue John from a Mr Bradbury of Castleton (Ford 2000, p. 56). Adam probably ordered the production of other Blue John ornaments for Kedleston through local masons, possibly Richard Brown & Sons, as Brown is attributed to a pair of Blue John obelisks in the Family Corridor (NT 109102). See also a pair of Blue John columns (NT 109103), an urn (NT 109104), and a pair of campana vases (NT 109107). Another rare Derbyshire stone, Ashford Black Marble, is set between the Blue John and white marble elements of the columns. It can only be mined from two quarries in the county and polishes to an extremely desirable deep and glossy black. Alice Rylance-Watson March 2019
