Glue is a very commonly used item for bonding different types of things. It is used in homes, schools, offices, manufacturing industries and other places.

The limitless importance of glue is not a recent discovery. According to Glue History, an online platform for knowledge about glue, bonding agents are pre-history. As far back as 4000BC, people used glue to manage the tools they used for survival. Archeologists who excavated ancient burial sites found that items such as clay pots had been repaired using glue from tree sap.

Ancient tribes also used collagen from bones, hides, skin and muscle from animals to make glue after discovering that collagen from animals was sticky and effective in keeping things bonded for long periods of time. For instance, the glue used by ancient Greeks and Romans to make mosaic floors and tiled walls was so strong that some of the structures are still intact. This is according to How products Are Made, a website that dispenses knowledge on production processes.

Although glue has been around for a long time, ThoughtCo, a general knowledge website says that the first patent for the production of glue was given in Britain in 1750. Glue made from fish was the first to be patented. Afterwards, patents for glues made from natural rubber, animal bones, starch, casein and other sources were given a go-ahead.

In 1942, Dr. Harry Coover an American Chemist accidentally discovered cyanoacrylate now commonly known as superglue.According to Wikipedia, the discovery happened while he was in the process of making gun sights for allied soldiers during World War II. He unintentionally made an extremely powerful adhesive.

Coover originally rejected the use of cyanoacrylate because he thought it too sticky. However, according to Glue History, in 1951 he changed his mind after discovering that superglue was very useful in bonding. In 1958, the mass production and marketing of superglue began.

Over time, glue has been used in the production and bonding of everyday items as well as complex inventions. For instance, adhesives from natural rubber are used to create a mixture for car tyres. Glue is also used in forensics for getting fingerprints from surfaces.

Because industrial glue contains such powerful elements, people have been advised to be careful in its usage. For instance, if superglue is used in skin to skin bonding, trying to remove it might result in wounds.

Inhaling glue fumes has also been said to result in anxiety, dizziness, headaches and nausea. Some studies also show that constant exposure to glue fumes for a long period of time may result in cognitive problems.
