Glass is made by melting different silicates at high temperatures (about 1500°C), specifically silicate sands mixed with calcium and sodium carbonate. It can be moulded when hot in various and innovative forms. The silicate mixture does not solidify at a pre-set temperature. This means that an object is made in a long interval period of processing during which the glass mixture undergoes a progressive increase in viscosity.
The elements of the vitrifiable mixture can make colourless or transparent glass. With the addition of small amounts of colouring substances, such as iron and chrome oxides for green, sulphur mixtures for yellow and cobalt for blue, a variety of shades and tones can be created.
Glass has infinite different applications in both industrial and household uses. Glass is a solid product that is very widely used and consumed. Its uses range from simple containers for foods, drinks, pharmaceutical and cosmetics to unusual art, furnishing and design objects, and structures and components in a wide range of specialized industries.
In the pharmaceutical industry, for instance, glass containers must ensure the vital task of keeping medicines unchanged over time. In this context, the choice of glass type is decisive, a decision made according to the characteristics of each product type rather than just based on the needs expressed by the customer/pharmaceutical producer. |
