A bstract A machine was designed to place tensile loads on glass fibers having diameters from 0.6 to 0.8 millimeter (0.024 to 0.032 inch). The results of tests on twelve glasses of known chemical compositions are given. The fractured surfaces exhibited characteristic smooth and rippled areas which were measured and correlated with the breaking loads. In order to compare the various glasses, it is convenient to use that value of the load per unit area which exists in a fiber whose fractured surface shows a smooth area that is 1% of the section. For the twelve glasses tested, these values ranged from 23.0 to 33.0 kg. per mm. 2 (32,500 to 47,000 1b. per sq. in.) when the load on the fiber was increased at the rate of 1 pound per minute.
