The laboratory is built up of chemical and physical sections. Physical laboratory is responsible for grading purchased raw materials before entering into the factory. If the materials do not meet the criteria and satisfy the requirements, then they are returned since grading plays a key role in solid objects’ homogeneity and mixing. The limit of acceptability has been determined for each material and its methodology is based on American Society for Testing and Materials (ASTM). Chemical laboratory is responsible to analyze, determine and identify rate of elements (such as silica, dolomite, lime, fluorspar, sodium carbonate, sodium sulfate and coke) used in glass production from entrance of raw materials to production and analyzing the product. Considering diversity of the raw materials and extreme sensitivity of the used combinations in glass and their percentage, the chemical laboratory, provided with the most advanced equipment, is able to analyze the materials and explain the glass standards.

Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB and EVA), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic of “spider web” cracking pattern when the impact is not enough to completely pierce the glass.
