Annealed Alkali-Lime-Silica Glass (IEC 60672 Type G-110)
Annealed alkali-lime-silica glass is a grade of alkali-lime-silica glass. The graph bars on the material properties cards below compare annealed alkali-lime-silica glass to other glass and glass-ceramics (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
