A glass bottle is a container first used to hold liquid. It is made of silica (glass) and coated with a clear varnish.

The manufacturing process of glass bottles is generally divided into four stages.

Melting stage. Is the process of cooling molten liquid into a liquid solid with a certain shape, this process is called melting.

The characteristics of the glass bottle

1. High transmittance, because it is a transparent glass bottle, the appearance of the wine bottle is bright and vivid, and has a strong visual impact.

2. Good heat resistance, the bottle body will not be deformed under high temperature.

3, acid and alkali resistance, corrosion resistance, can hold all kinds of corrosive liquids and liquids, will not be eroded by harmful gases in the air.

4, high strength, under the action of external force is not easy to damage.

Materials for making glass bottles

1. Glass materials: silicon, alumina, calcium oxide, magnesium oxide, sodium oxide, etc. Use glass bottles to package volatile food, because the alcohol in the wine after evaporation will form alcohol vapor pressure drop, less air in the bottle, will not cause the deterioration of the wine.

2. Colored glass materials: red agate, grape stone, etc. Because it can make colorful glass bottles.

3. Coated glass materials: such as glass bottles coated with resin or metal-plated.

4. Amorphous glass materials: such as flexible glass bottles, also known as "jelly bottles". The bottle does not need to be glued for use and can be placed directly into food.

The use of glass bottles

1. Bottle food: milk, oil, juice, etc.

2. Bottle medicines: such as vaccines, antibiotics, etc.

3. Bottle made cosmetics: such as cleanser, liquid foundation, eyebrow pencil, etc.

4. Bottle ceramics: such as bowls, cups, etc.

6. Glass bottles are also used to make other kinds of glass for sale, such as wine bottles, sugar jars and so on. Glass bottles are widely used in food and chemical fields. Because of their low material, fragile and easy to clean, they are widely used in the manufacture of all kinds of containers. However, due to the characteristics of the glass bottle material itself, especially the thickness of the glass bottle has a great impact on its compressive strength, so it must be paid attention to when it is used. In the field of food consumption, it is very common to use glass containers to pack food and drinks.

The use value of the glass bottle

1. First of all, the glass bottle is a commonly used container, first used to hold liquid. For example, beer, wine, liquor, juice and other liquid containers are mostly glass bottles;

4. In addition, glass bottles are also a tool for preserving valuables. For example, some precious items such as gems are all stored in glass bottles. Because of its high density, it is not easy to be corroded and polluted, and can be very good at protecting valuables.

The process of making glass bottles

1.Billet preparation. The first is to make glass with quartz sand, feldspar and soda ash and other raw materials.

2.Heat the prepared raw materials in the pot. First, stop softening the billet.

3.Stop stretching the billet. The billet is heated to a certain temperature and continued for a period of time, allowing it to cool.

4.The billet after secondary cooling is stretched thin and leveled.

5.Then stop the grading, coloring and other processes.

6.Finally, the bottles are cleaned, shaped, and then packaged, filled, sealed, etc., to make the finished product. The feature of this process is that only two steps are required.
