Decrease of the production of the excellent red and white silica bricks has been regarded as the main cause of degeneration of silica bricks, so that a number of researches are being made at various places with respect to manufacturing silica bricks from materials other than red and white silica. The author made success in manufacturing excellent silica bricks from the Manchukuo white silica at the branch factory (managed by the Kurosaki Yogyo K. K.) situated within the yard of Syowa Seikojo (Syowa Steel Works). The result of the actual use since the end of 1936 at the Steel Department factories of Syowa Seikozyo indicated results rather better than the case of silica bricks made from the Japanese red and white bricks. In the present paper, the author summarized his opinion on the cause of failure of silica bricks in the open hearth furnace practice, and the method of testing silica bricks for the dome of the open hearth furnace. On the ground of the aforementioned researches, the author reported the process of studying the manufacture of silica bricks together with the actual result of its practice.
