91 the Company makes from this substance. This kind of brick has of late years been laigely used, e. g. for the new Post Office and Christiansborg Palace. Bricks made from siliceous clay form an excellent insulating material for heat, in consequence of which they are used for the insulation of ovens, and they will undoubtedly be much sought after for walls in cold countries, and because of their lightness they are very suitable for bay- windows and the like. Hollow moulded bi'icks are used for the insulation of iron constructions against fire, they being laid round columns and brackets. Insulating material is made from siliceous powder placed round steam pipes and the like. Natural siliceous powder is used as a lining, and burned sili- ceous powder for lawn tennis courts. The specific gravity of ordinary siliceous clay brick is abt. 1, and its heat-conducting capacity is only 1/3 of that of fireproof bricks, but for the insulation of boilers an especially porous brick with a still lower specific gravity and heat-conducting capacity is made by the Company.

When washed kaoline is used in the manufacture of paper and porcelain, in its natural state it is used for the production of fire-proof bricks and chamotte bricks.
