Chemical

Weathering: 1Weathering is defined as corrosion by atmospheric-bornegases and vapor such as water and carbon dioxide. Glassesrated 1 will almost never show weathering effects, thoserated 2 will occasionally be troublesome, particularly ifweathering products cannot be removed, those rated 3require more careful consideration.

Durability:Durability is measured via weight loss per surfacearea after immersion. Values are highly dependent uponactual testing conditions. Data is reported for EAGLE2000

and Corning 1737 glasses run concurrently. Unlessotherwise noted, concentrations refer to weight percent.
