Soda and lime are added to a glass batch in the form of soda ash (Na2CO3) and lime- stone (CaCO3). During heating, these two ingredients decompose to give off carbon dioxide (CO2), the resulting products being soda and lime. Compute the weight of soda ash and limestone that must be added to 125 lbm of quartz (SiO2) to yield a glass of composition 78 wt% SiO2, 17 wt% Na2O, and 5 wt% CaO.

13.10 What is the distinction between glass transition temperature and melting temperature?

13.11 Compare the temperatures at which soda- lime, borosilicate, 96% silica, and fused silica activation energy between temperatures of 900 and 1600°C.
