Glass has accompanied technical developments since ancient times.
A universal material, it is now used in various industries: Nuclear, Aerospace, Construction, Transport, Pharmaceutical, Food, Medical, Electronic, etc…
The various positive qualities of glass explain the appeal.
An excellent optical material, its strong transparency, and its optical properties make it an essential material for numerous applications (lighting, imaging…).
Its physical properties are also renowned, such as durability, strength, resistance to wear and even chemical attacks. A durable material, glass keeps its transparency and shine even when subjected to difficult environments over long periods of time.
An environmentally friendly material, glass is mainly produced from sand. In terms of environmental protection, glass has various undeniable assets such as a better carbon balance than plastic materials derived from petrol, as well as being completely recyclable.
It does not contain any heavy metals (cadmium, asbestos, lead, mercury), and thus glass is fully RoHS compliant
Three major glass techniques
In the glass industry, there are three major production types.
- Float glass: mainly used for glazing,
- Hollow blown glass: bottles, bulbs, flasks…
- Pressed glass: the niche market where Holophane is a leader.
This technique provides varied shapes which cannot be created with float glass or blown glass.
