Glass is a substance inorganic, homogeneous and amorphous. Its main features are transparency / translucency, hardness and total recyclability.

The so-called flat glass, manufactured in sheets, are mainly consumed by construction, followed by the automotive and furniture industry, after the production of mirrors and a small percentage for many other applications. Several sectors are increasing their consumption of glass, as the furniture industry and the household appliances, such as stoves, refrigerators, microwaves, etc.

The printed glass is a translucent glass plane, colorless or colored, which receives the impression of a texture when it is out of the oven. It has wide application in construction, appliances, furniture, decoration and household items. Currently, there is a wide range of modern and sophisticated textures, some more transparent, others more translucent, which provide well-being, warmth and privacy to environments.
Sand: Consisting substantially of silica (SiO2), which is the basis of most glasses. It provides silicon oxide.

Limestone: Mineral composed of calcium carbonate (CaCO3), which is mined, crushed and ground until obtaining the desired grain size distribution. It provides calcium oxide (CaO) to the glass.

Dolomite: The same limestone family, however, the formulation consists of a double carbonate of calcium and magnesium.

Feldspar: It is a mineral consisting of an aluminum sodium silicate and potassium. The reason for its use is the source of aluminum oxide or alumina (Al2O3).
Soda ash: (Na2CO3) is the main supplier of sodium oxide. Although its percentage by weight is not so great, is the higher cost raw materials of glass soda-calcic. It works as a melting agent.

Sodium sulfate: (Na2SO4) it is a refining agent, releasing the bubbles contained in the mass of glass caused by the reaction of other raw materials.

Glass cullet: Used in virtually all glass industries, as well as 100% recyclable, reduce energy consumption, increase the extraction capacity and also increase the life of the furnace.
