Drum Fireclay Pits, East Whitburn, West Lothian.

Robertson, Love & Co were liquidated in 1916 but continued to make firebricks as part of United Collieries Ltd. When coal was nationalised in 1947, the brickworks were reorganised as United Fireclay Products Ltd. and comprised the Etna and Atlas Firebrick Works, the Bathville Pipe Works, the UNICOL Tile Works, all at Armadale and the Brownhill Building Brickworks at Clelland, Lanarkshire. The chief refractory brands were Etna (33% alumina), Atlas (38% alumina), and Atlas A (42% alumina), all based on local fire clays. The Bents Mine near Stoneyburn supplied an excellent 42% alumina fireclay from which the Mars brand was made, but the fireclay was worked out and the mine closed in 1929. The Drum Mine near East Whitburn took over and the Northrigg No 7 pit supplied fireclay for pipes and some coal. The Tippethill Mine (38% alumina, 2.5% iron) replaced the Drum Mine in 1960 and the Pottishaw Mine replaced Northrigg in 1963.

Below – Information – British Geological Survey. Ganister from the United Collieries Limited Drum Pits, Torbanehill, Whitburn near Armadale, Linlithgowshire
This specimen of ganister is from Ganister from the United Collieries Limited, Drum Pits, Torbanehill, Whitburn near Armadale and is Carboniferous, Millstone Grit in age.
The works associated with the pit were called the Atlas and Etna Brickworks at Armadale about half a mile south-east of the village.
Ganister is a highly siliceous bedded sedimentary rock that resembles quartzite. The name Upper Fireclay has been given to a group of fireclays and ganisters in the upper part of the Millstone Grit. In the Bonnybridge district of Stirlingshire, a few miles east of Falkirk, the economic value of the Upper Fireclay has long been recognised and the beds have been
extensively worked. The Upper Fireclay includes both refractory clays and ganisters.
