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 have added the Scottish tag here as although the bricks themselves were manufactured in Northumbria, the clay was mined in Scotland.)
During the First World War, (c1916) Adamsez Ltd, sanitary ware manufacturers, of Scotswood, Newcastle, diversified into the manufacture of firebricks under the name, Scotswood Furnace Company. It was operated as a subsidiary to W C Gibson and Co Ltd. When G H Ramsay and Co were taken over by Adamsez Ltd in 1923, refractory brick manufacture was moved to their premises at Swalwell. The business was then separated from W C Gibson and Co Ltd and became Adams Pict Firebrick Co Ltd.
c. 1930 – c 1959 – Adam Pict Fireclay Company – Border Quarry, Saltcoats – This company was based in Newcastle-upon-Tyne. The quarry at Border Farm, Saltcoats worked a seam of bauxitic clays and was started in the 1930s. It continued after the 1939 – 1945 war, closing about 1959. – Source Kenneth Sanderson. The Scottish Refractory Industry. (Note – SBH – It is highly likely their bauxitic clay was sourced from the Ayrshire Bauxitic Clay Company).
