The authors carried out table tests on the silica bricks acquired from some brick making works and measured the specific weight, porosity, refractoriness, especially with regard to the plasticity at 1690℃, at which sillica bricks commonly soften. These measurements were compared with the results from the service test of a working open hearth furnace. The table test of silica bricks concerning the plasticity was found to gree well with the service result. It may be applied to presume the quality of silica bricks before using it in service.
