Uses of Glass and its Applications to Man

The glass is one of the early discoveries of man. It was made out of molten sand. The uses of glass are indispensable, i.e., there will be no alternatives to it in some cases. Its applications to man include

  1. Kitchenware
  2. Eyeglasses and lenses
  3. Electronic Screens tv
  4. Microscopes for magnification
  5. Lights and bulbs
  6. Storage of specimens, harsh chemicals
  7. Automotive
  8. Housing, furniture, and decoration
  9. Laboratory handling
  10. Communication optic cables.

The ability of glass to withstand high temperatures up to 1000 degrees Celsius, chemical inertness and inexpensive makes it widely used in humans life.

Uses and Applications of Glass

Kitchen ware: Most kitchens in the world would have some form of glass made utensils, vessels, glasses, jugs, etc. In the modern kitchen, the use of glass is further enhanced. It is used as a container for pickles, dry powders, milk, oils, ghee storage, etc.

It might be a fact to say that you will not find a kitchen without a glass container.

Eyeglasses: Many people in the world suffer from eyesight related problems. Some suffer from short sight, while others with a long site. Glasses and lenses are used to correct their vision as a part of medical treatment. These glasses have a different range of curves to adjust the sight.

Though glass is still widely used, there are improvements in technology to make lenses with other materials as well.

Electronic Screens: The screens of your mobile phone, computers, television are made of glass. This is based on their transparent nature besides protecting the inner part of these devices.

Microscopes for magnification: Microscopes are used to observe minute objects or organisms by magnification. Due to the microscope, scientific knowledge and medical technology got advanced a lot.

Microscopes have magnification lenses to enhance the size of the object for clear vision to our eyes. These magnification glasses are made of pure glass. They are not replaceable by any other sort of materials like plastic, metals, etc.Microscope lenses made of glass

Microscopes find enormous use in disease diagnosis like anemia, microbial infections, etc. Without these glass made magnifying lenses, it won’t be possible to use microscopes.

Lights and bulbs:

These are the other objects used by a man daily. We use them to illuminate out homes, offices, roads, during travel, etc. These bulbs have a filament to generate light. But these filaments are covered by a transparent glass. Besides protection, they allow passage of light through them without obstruction. You cannot replace the glass with metal or plastic as they are not either transparent and heat resistant.

You will notice that the bulb in your room would be hot if you hold it when it is switched on. In case the bulb is covered by plastic instead of glass, it could melt due to intense heat. This does not occur with glass as the glass can withstand a temperature of 1000°C.

Further, glass is also used for the light source in spectroscopy techniques like UV visible, fluorescence spectroscopy, etc.

Storage of specimens and harsh chemicals:

Specimens are well stored in a glass container. Hence, you can notice biological samples stored in glass containers dipped in formalin. Glass containers can retain the specimens for a long time as they can be sealed and made airtight. Further, they do not react with organic solvents used to store the specimens.

Automotive: Automobiles are the best commuters for man. And it is very difficult to find a car, bus or airplane which does not have glass shields. Glass is transparent and provide a clear vision to the drivers. Further, they are strong and withstand winds hitting the vehicle.

Housing, furniture and decoration: Use of glass to windows, door, ceilings add beauty to the home. Even small furniture like tables is made of glass to give a better appearance to the home.

Laboratory handling: Have you noticed that all the acids, bases and other chemicals are stored in glass containers in your chemistry lab. This is because they are highly resistant to chemical interaction and allow them to keep a watch on the sample during the experiment.

You can perform titrations, mixing, measuring the liquids with graduated glass containers. The only caution is you should not drop them to break them.

Optical fiber for communication: These are cables made of drawing glass. Though they are similar to electric cables, they differ in that they carry light. These wires are used for communication in place of metal cables. They have advantages like minimal chances of loss in the signal during transit. Further, the glass fibers are not affected by electromagnetic interference.

Further, uses of glass are also seen in the maintenance of fish aquariums. Glass made of lead and barium are also helpful to prevent radiations.
