27,619. Collins, H. A. D. Dec. 4. Fire-bricks.-In the manufacture of fire-bricks from pulverized silicious material (such as quartz or sea sand) and calcium hydrate or other equivalent alkaline substance (such as caustic soda or soda ash), the material is moulded to shape in the heated state and under high mechanical pressure. The bricks are afterwards burnt in a kiln in the usual manner. Before burning, the brick may be subjected to steam pressure to facilitate chemical action. The materials are kneaded in a steamjacketed pug-mill together with steam or hot water to give plasticity, and then pass into the mould.
