Incorrect relative humidity in glass objects can lead to crizzling or weeping of glass. Crizzling can occur when relative humidity is below 40%, and lead to cracks in its surface. Glass weeping or sweating can occur when relative humidity is above 55% and loses luster. [6] Thieves and vandals are a potential problem for any object. Since glass ...
Broadly, modern glass container factories are three-part operations: the "batch house", the "hot end", and the "cold end". The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment.
