Glass has always been used by people since ancient times. The glass, which is in a transparent, but hard form, is an inorganic and amorphous material that can be easily broken.

The first crystal glass was produced in Venice in the fifteenth century. A Venetian glass master mixed lead oxide into glass to produce leaded glass. However, the production of large glass sheets as used today began in 1902. Two years later, the first glass jars and bottles were produced by machine.

The first glass factory in our country is the Paşabahçe glass factory (1934) established during the Republican Period.

Silicon is the main raw material of glass. So it's sand. Glass is produced by melting siliceous sand in fire and adding some substances into it. The glass continues to maintain its amorphous structure as it cools and solidifies. This amorphous structure is a very important factor in the robustness and transparency of the glass.

Glass has been used as ornaments and household items for many years since it was first produced. However, it is widely used in various fields such as space technologies and communication. For very specific applications, many different forming methods are applied such as glass, pressing, flotation, pouring, drawing and foaming.

In fact, glass is a liquid and the transparent appearance of the glass is due to its liquidity. In some cases it is also considered a glass mine. The most important feature that makes glass different from other metals is its melting point. Glass is softened when heated at high heat and can take any shape. For this process, the glass usually needs to be heated above 800. However, when the 500 degree is exceeded, the glass melts.

The factor that makes the glasses durable and high quality is the proportion of materials such as silica and aluminum used in the production.

In general, glass is of two types for commercial use:

• Soda glasses are ordinary glasses. Its production is very low cost.
• Special glasses are glass with some outstanding properties such as melting temperature, chemical resistance and electrical conductivity. Therefore, production costs are high. For example, optical glasses are of very high quality and have the ability to refract light. Window glasses, spectacle lenses, television screens and decorative building materials belong to the special glasses group.

Laboratories and test and inspection organizations take into account the current regulations and published domestic and foreign standards when performing glass tests. Many standards for glass testing have been published. Here are a few of them:

• TS 3539-2 EN 1279-2 Glass - Used in buildings - Glass based insulating units - Part 2: Long-term test method and properties for moisture permeability
