Clear Glass of 1st hydrolytic class is differentiated by 33 expan-sion (Type 1, Class A) and 51 expansion glass (Type 1, Class B), whereas amber is generally worldwide only available as 51 expan-sion glass. The indicated lower expansion coefficient of 33 implies that this harder clear glass has to be processed at higher tempera-tures. These

The higher density of the glass surface gives it a higher water resistance. In glass of the 1st hydrolytic class one differentiates between glass with coefficients of expansion 33 (type 1, class A) and 51 (type 1, class B), whereby brown glass is only available with expansion coefficients 51 worldwide.
