The calculation of glass properties allows "fine-tuning" of desired material characteristics, e.g., the refractive index. [1]The calculation of glass properties (glass modeling) is used to predict glass properties of interest or glass behavior under certain conditions (e.g., during production) without experimental investigation, based on past data and experience, with the intention to save ...
The batching matrix B indicates the relation of the molarity in the batch (columns) and in the glass (rows). For example, the batch component SiO 2 adds 1 mol SiO 2 to the glass, therefore, the intersection of the first column and row shows "1". Trona adds 1.5 mol Na 2 O to the glass; albite adds 6 mol SiO 2, 1 mol Na 2 O, and 1 mol Al 2 O 3 ...
Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension .

The cost overruns constituted 33% of the total expense. The budget for the bridge increased to 150%. The cost overruns exceeded the original budget by 50%. The final example is the most commonly used as it specifically describes the cost overruns exclusively whereas the other two describe the overrun as an aspect of the total expense.

The glass exhibits a change in refractive index, called index drop, during the annealing process. This drop is caused by fast cooling of the mould insert, inducing a small amount of residual stress in the glass. As a result, the glass exhibits a small index change when compared to its fine anneal state.
