04/07/1939 – The Scotsman – Lanark County Council has been given notice by H. M. Inspector of Mines of the abandonment of the following mines … Lauchope Mills Mine Chapelhall, belonging to the Bonnybridge Silica and Fireclay Co, Ltd, Bonnybridge.
(Note – SBH – I am unsure if the references below all refer to the same mine or several mines in the same area. It is often difficult to differentiate between clay mine references and to whether they relate to the Weir Castlecary Works or the Stein Castlecary Works. This page hopefully, just records those related to the Stein Castlecary Works).
This mine was sunk to supply the Stein Castlecary Fireclay Works with high alumina grade clay. (Thistle fireclay). Silica clay was also found and this was used to manufacture silica-based firebricks.
27/07/1901 – Kirkintilloch Gazette – At Castlecary Clay Pit a new shank is at present being sunk and for the next few weeks the clay required to keep the fireclay works in full swing will be obtained from a mine along the banks of the Red Burn, to the south of the Castlecary road. The raw material is being driven to the works, the contract for the carting being in the hands of Mr John Anthony, Kilsyth. The alterations, it is expected, will cost £1000.
20/04/1903 – Work starts on the mine.
04/11/1903 – Clay was reached and a further return airway shaft was dug and this took 7 months.
c. 06/1903 – Clay was being mined.
17/07/1926 – Falkirk Herald – On Monday a partial resumption of work took place in Messrs J. G. Stein’s Castlecary clay pit. Work in this pit had been stopped since the commencement of the mining dispute, owing to lack of coal, but supplies of foreign coal have been received. Twenty-six men commenced Monday, and more started on Tuesday.
11/10/1941 – Falkirk Herald – Fatal accident. Last Saturday morning a 59-year-old clay-miner named John Bullions, lost his life in a distressing accident at Castlecary. Deceased, who resided with his niece, Mrs Walker, at Main Street, Longcraft, was employed as a repairer in the Castlecary clay-pit of the General Refractories Company, Ltd., and was following his regular occupation when there was an unexpected fall of material from the side-wall of the worHing. Bullions received severe head injuries, from which he succumbed shortly afterwards.
