Glass is a hard material, normally brittle and transparent, common in our daily lives. It is mainly composed of sand (silicates, SiO2) and an alkali. These materials melt at high temperatures (molten viscous state); they are then rapidly cooled to form a rigid structure.

What is glass and how is it produced?

Glass is a hard, brittle, transparent and amorphous inorganic material found in nature, although it can also be produced by humans. Artificial glass is used to make windows, lenses, bottles, and a wide variety of products. Glass is an amorphous type ceramic material.

What is glass and how is it made?

Chemically, commercial glasses are produced from inorganic oxides, of which silica (sand) is generally the main constituent. On the other hand, it is possible to cool certain organic materials without crystallization.

What kind of material is glass?

According to the RAE, glass is a “hard, fragile and transparent or translucent material, without a crystalline structure”. This material is made up of silica sand, sodium carbonate and limestone, which melt at around 1,500°C.

How to explain to a child how glass is made?

Glass is made from silica from sand and other substances such as sodium carbonate (Na2CO3) and limestone (CaCO3). We could say that it is made from 3 substances, a mixture of quartz sand, soda and lime. These 3 elements are melted in a furnace at very high temperatures, approximately 1,400ºC to 1,600ºC.

How is glass made?

Glass is obtained from a mixture of siliceous sand or clay with powdered dry metal oxides that are introduced into a fusion reactor at temperatures exceeding 1000ºC.

How was glass made in the Middle Ages?

The production of domestic glass objects in the Middle Ages is characterized by the predominance in the use of the blowing technique; the main component is silica with added metal oxides of sodium, potassium, calcium and magnesium.

What kind of material is glass and plastic?

Glass is an inert material that does not impact or transfer flavor to the food or drink it contains. It can be reused as many times as desired without any problem and without losing quality. Plastic is much more porous. It also contains chemicals that can pass into food or drink.

What kind of mixture is glass?

Glass is a hard material, normally brittle and transparent, common in our daily lives. It is mainly composed of sand (silicates, SiO2) and an alkali. These materials melt at high temperatures (molten viscous state); they are then rapidly cooled to form a rigid structure.

What elements make up glass?

In addition to SiO2, Na2O and CaO, which make up approximately 90% of its composition, soda-lime glass has other elements, some of which come from the raw material used, such as iron oxide (Fe2O3), and others purposely added to give the glass desirable characteristics, as is the case with …

What are the properties of glass?

glass characteristics

A hard material, even when very thin. A brittle material if lightly bumped. A malleable material through different methods that allow a different finish to be achieved, such as tempered, annealed, thermo-acoustic, armored, laminated glass, among others.

What is the origin of glass?

The oldest glass remains date from about 5,000 years BC and have been found in areas of Asia Minor, Mesopotamia and Ancient Egypt. The first pieces made entirely of glass date back to 2,100 BC, in which the molding technique was used.

What kind of material is plastic?

Plastic is a lightweight, durable, cheap and easy to modify material. It is made up of polymers, which are large organic molecules made up of repeating carbon units or chains called monomers, such as ethylene, propylene, vinyl chloride, and styrene.

What is plastic glass called?

METHACRYLATE OR PLEXIGLAS SHEETS

A resistant, light, unbreakable, flexible and insulating plastic material that is used in many sectors (printing, architecture, decoration…) It is a good alternative to glass and, for this reason, it is also known as acrylic glass.

What is plastic glass called?

Synthetic glass or plastic glass is an alternative to glass as we know it. In this case it is a much lighter material, but it is still resistant to shocks and temperature changes. … 1.2 Methacrylate or acrylic glass.

How was glass made in ancient times?

TECHNIQUES IN ANTIQUITY

Strips of glass were made, which were then melted together in a mold, producing slatted glass. Highly complex designs were made using the mosaic technique, in which elements were cast in cross-sections which, once cast, could be cut into sheets.

What is the main raw material of glass?

Glass is obtained mainly from the following raw materials: A vitrifying agent: silica (high quality sand). Alkalis to change the state of silica from solid to liquid (sodium and potassium carbonates).

What techniques are used to make glass objects?

Within the fusion technique there are several techniques to manipulate glass, of which the best known are:

    Blown. … 1.2 Fusing. … 1.3 Laundry. … 2.1 Direct engraving. … 2.2 Acid etching. … 2.3 Engraving by sandblasting.

What are the intensive properties of glass?

An example of an intensive property is electrical conductivity. As for the This gives the flat glass a weight of 2.5 kg/m2 (this indicates each millimeter per thickness). Regarding the manufacture, with the for many years, giving it health. he always values ​​the color of what he drinks.

What are the properties of a paper?

For impeccable printing, paper must have the following intrinsic properties: whiteness, color, lightness, gloss, opacity, porosity, smoothness, grammage, bulk density, hardness and compressibility, thickness uniformity, dimensional stability, sizing, internal structure.

What are the mechanical properties of glass?

Glass always breaks due to tensile stresses on its surface. It varies according to the duration of the load and ranges between 300 and 700 K/cm2. For permanent loads, the tensile strength of glass decreases by 40%. The higher the temperature, the lower the tensile strength.
