Glass - what kind of glassware is it and what is it intended for?

We are surrounded by so many objects that we almost always take them for granted. However, each of them has its own history, varieties, and sometimes a “brother” with the same name, but a completely different purpose. For example, a glass.

What is a glass?

In the most general sense, it is a vessel without additional parts (handles, legs, etc.). Its shape is usually cylindrical, although specimens that widen upward are often found. This item may vary in:

• height and width;
• material;
• wall thickness;
• degree of transparency;
• registration

Where and how is it used

Its most common use is in everyday life, as tableware. Cold or hot drinks such as water, juice or tea are poured into it.

By the way! In Soviet times, on every train the conductors offered hot tea, which was served in a glass glass. To protect the passenger and make the vessel more stable, it was inserted into a special stand with a handle - a cup holder.

Almost every housewife who is not indifferent to cooking, and also uses multicooker has a measuring cup. It has special divisions showing the volume of liquid or bulk product, as well as its filling by 1/4, 1/2 and 3/4.

Also in everyday life you can often find a glass for stationery: pens, pencils, rulers. Often in the bathroom there are toothbrushes and toothpaste.

Metal glasses are found in medical institutions. They are used for sterilization, disinfection and sterile storage of medical instruments and materials. These can be thermometers for measuring the temperature of patients, cotton swabs and much more.

Chemical laboratory workers use special cylindrical cups with a flat bottom to prepare complex solutions. They are equipped with a spout to make it convenient to pour liquids.

What materials is it made from?

There are a wide variety of materials for the production of glasses:

Glass is perhaps the most common raw material. Glass glasses can be seen in every home, in cafes and restaurants, in government institutions. They can be smooth, faceted and grooved, transparent or colored, with or without a pattern.

Crystal is an alloy of glass with lead or barium. Products made from it are distinguished by durability, heat resistance, transparency, characteristic shine and melodious ringing.

Synthetic polymers. Today, plastic cups are sold on every corner and are almost always used as disposable cups. They drink from them and also make all kinds of crafts. Many summer residents grow seedlings in them. Plastic glasses are thicker and can last for several years.

Paper (cellulose) is used to produce disposable drinking utensils. It is more environmentally friendly and, unlike plastic, does not have a negative impact on the environment when disposed of. Used in fast food outlets such as McDonald's.

Dough: used to make waffle cones. This is both a container that does not need to be thrown away later, and a tasty “bonus” for ice cream.

Steel and other metals - their products are found in medicine and mechanical engineering.

Where else can you find the concept of “glass”

The glass can be a part of the body of a mechanism, for example:

• bearing;
• military projectile;
• gearboxes and more.

Brokers and traders are well familiar with the term “book of exchange”. In other words, these are the people who buy and sell securities. This is a table of orders with which you can analyze the relationship between supply and demand in the market in a specific period of time.

A glass, of course, is not only a familiar thing, but also a necessary one. The stable design ensures its impeccable functionality. This, in turn, allows it to be used in many areas of life. Other characteristics, including aesthetic ones, depend on the imagination of the manufacturer, and sometimes the desires of each specific consumer.
