Abstract
Results are given of a series of softening point tests upon several types of refractory materials in which the rate of heating to obtain cone 28 down was varied from one hour to five hours. The results are presented in order to show that much of the data obtained by a fusion furnace is dependent upon the rate at which the furnace is heated and that large variations will occur unless care is taken to duplicate conditions of previous tests. Conclusions reached were: that two laboratories must duplicate the essential conditions in order to obtain agreement that the furnaces should be of the same type and heated in a similar manner, that the variations reported by different investigators can often be traced to the fact that conditions have not been duplicated.
