Abstract: Two commercially available float glasses, a borosilicate and a soda-lime-silicate, were subjected to an increasing number of abrasion cycles to determine the effects of the abrasion-induced contact damage on haze and flexure strength. The borosilicate did not decrease in strength and had a minimal increase in haze through and after 150 abrasion cycles as compared to the soda-lime-silicate glass. After 300 abrasion cycles, the strength of both glasses was essentially the same, but the haze of the soda-lime-silicate was significantly higher than the borosilicate glass. These results show that the borosilicate glass is more abrasion resistant than the soda-lime-silicate glass.
