This special shape was found by Ian Suddaby on the site of the long vanished locomotive engine sheds at Carlisle. Several other firebricks found nearby were parts of a locomotive firebox and this might have been too. I imagine a shaft of some function went through the hole. This example is not in my possession….

1914 – The Hurll, Garnqueen Works was closed at the start of the 1914 war due to shortage of labour. The steel industry was desperately short of calcined magnesite for fettling the furnaces, as this magnesite was all imported from Austria, so raw magnesite was imported from as far away as Manchuria and calcined by the Eglinton Silica Brick Company of Coatbridge. To supplement their production they took over the Garnqueen Works to make more calcined magnesite or periclase. After the war, the Garnqueen Works was used to make briquettes from iron ore fines for the Tharsis Company thus enabling them to be used for the blast furnace feed …

1920 – The Eglinton Silica Brick Co., Ltd. 45, Renfield Street, Glasgow. The silica-brick trade in Scotland was started by the Eglinton Chemical Co., of which the present company was originally a branch, about the year 1876, for the supply of silica bricks to Scottish Steel Works. The raw material at first employed was flint from County Antrim, Ireland. Later, chalk flints were imported from the Thames and, to a certain extent, from the northern shores of France. The Thames flints could at one time be bought at 5s. to 6s. per ton c.i.f. Grangemouth. These flints were calcined in shaft kilns, and each kind had different characteristics; the French flints, while purer chemically, were low in fusion point. The bonding material was highly plastic clay obtained from South Wales. The bricks were moulded by hand machines, which, until recently, were exclusively used in this country for moulding silica bricks; these have now been superseded by power presses, which are doing just as satisfactory work as that done in the past by manual labour. After being dried, silica bricks were burned in Beehive kilns, at a temperature of about 1400° C. These flint bricks contained about 93 per cent, silica, the balance being alumina, lime and iron. They were chiefly used in the chequers of steel furnaces, where they would stand better than the best English bricks. They were, however, used also in the crowns of steel furnaces in several works in Scotland, as well as in other parts. One great advantage of these bricks consisted in their less expansion than other silica-bricks, and they were, therefore, better able to withstand variation of temperature without cracking. Also, they could be employed in furnaces for repairs during fettling, and for this purpose alone were in great demand. Until recently little enquiry had been made as to the ganisters used in Scotland, but, judging from the samples that have been hitherto submitted to us there is nothing in this country to compare with the English ganister. There are, however, considerable deposits of quartzite in the islands and west coast of Scotland which have been brought to our notice by the Geological Survey, and which, we believe, could be easily delivered at Glasgow at prices which should enable them to be used for refractory purposes. Quartzites are largely quarried in the United States for the raw materials of silica-brick manufacturers. Practical tests have been made of the samples submitted, and our opinion is that the deposit -Sample No. 2 (North side of Loch Leven, Ballachulish, 1 mile east of Callart Cottage), might be expected to give the quartzite best fitted for tile manufacture of silica-bricks. The Eglinton Silica Brick Company is at present (1916) entirely engaged in the manufacture of magnesite bricks from imported material. The above information and report on samples has been kindly supplied by Mr Wm. Donald, Manager of the Eglinton Silica Brick Co.

Plastic clay was a raw material that was used as a bonding material in the silica-brick trade. British Geological Survey Petrology Collection sample number MC 7443. It is recorded that in the 1870s the Eglinton Silica Brick Company Limited, 43 Renfield Street, Glasgow used plastic clays to bond silica-bricks made from flints either imported from the Thames area or northern France and that the bricks were bonded with highly plastic clay from South Wales. The resulting bricks were used in steelworks. There is no evidence that plastic clay from this locality was worked, though it was collected during exploration for natural resources.
