Glass is a material obtained by cooling molten substances. Glass products can serve various purposes, such as being transparent, structural, decorative, insulating, and more.

Quartz glasses, on the other hand, are glass-crystalline materials obtained through complete or partial crystallization of glass. Quartz glasses are highly durable substances, resistant to chemical and thermal effects. Various structural and finishing materials, dielectrics, as well as adhesives for metal, glass, and ceramics, can be produced from quartz glasses.
