description abstract	This specification covers the glasses commonly used to manufacture laboratory glass apparatus. Three types of glasses are included: Type I, Class A which is a low-expansion borosilicate glass, Type I, Class B which is an alumino-borosilicate glass, and Type II which is a soda-lime glass. Different tests shall be conducted in order to determine the following properties of glasses: linear coefficient of expansion, annealing point, softening point, density, and chemical durability.
