Synthetic glues like Elmer's are made of polyvinyl acetate (PVA) emulsions. The word emulsion refers to the fact that the PVA particles have been emulsified or suspended in water. The thinner the glue, the more water it has in it.Know More
In addition to water and PVA, synthetic glue can also contain ingredients like ethanol, acetone, and amyl acetate. Ethanol slows down the drying time, acetone speeds up the drying time, and amyl acetate slows down the evaporation of the glue. However, some natural glues – called hide glues or protein adhesives – are made from animal proteins or gelatin. This is why people often speak of dead horses being sent to the glue factory.
Humans have been experimenting with animal-based adhesives for thousands of years, and the world's oldest glue on record has been carbon dated as being over 8,000 years old. Archaeologists discovered the glue in Israel in a cave near the Dead Sea. The glue was made from collagen, an animal protein, and it was used as a water-sealant, an adhesive and a protectant.
Four thousand years ago, ancient Egyptians used similar collagen-based glues in furniture construction, and about 1,500 years ago, Native American people used collagen-based glues while making bows for hunting and batlle.Learn more about Chemistry

While it is better to attempt to remove Elmer's glue from carpeting while it is still wet, there are a few different ways the glue may be removed. Dabbing the glue with a paper towel moist with water or vinegar may often loosen Elmer's glue and allow for easier removal.Full Answer >
Remove water-based glues from clothing by scraping off softened glue and then laundering the garment in hot water after pretreating the glued area. If the glue has already hardened, then soften it before scraping it away. Consult the manufacturers of non-water-based glues for removal instructions.Full Answer >
There are many types of edible glue, but one of the most popular and simplest glues to make is tylose glue. To make tylose glue, you need tylose powder and water. Tylose glue is best used for cake decorating or creating edible buildings, such as a gingerbread house. Tylose powder can be found at bakeries or stores that carry cake decorating supplies.Full Answer >
