    i found this info on glue so here it is what glue is made of: Glue is a gelatinous adhesive substance used to form a surface attachment between discrete materials. Currently, there are five basic types of glue. Solvent glues comprise an adhesive base mixed with a chemical solvent that makes the glue spreadable; the glue dries as the solvent evaporates. Most solvents are flammable, and they evaporate quickly; toluene, a liquid hydrocarbon made from fossil fuels, is often used. Included in this category are glues sold as liquid solders and so-called contact cements. Water-based glues use water as a solvent instead of chemicals. They work slower than chemical solvent glues; however, they are not flammable. This category comprises such glues as white glue and powdered casein glue, made from milk protein and mixed at home or in the shop. Two part glues include epoxy and resorcinol, a crystalline phenol that can be synthesized or made from organic resins. One part contains the actual glue; the other part is a catalyst or hardener. Two part glue is very useful for working with metals (automobile dent filler is a two part glue) but must be mixed properly to work well. Animal hide glues are useful for woodworking and veneer work. Made from the hides as well as the bones and other portions of animals, the glue is sold either ready-made or as a powder or flake that can be mixed with water, heated, and applied hot. Cyanoacrylate glues, usually referred to as C.A.s, typify the newest and strongest of modern glues, which are made from synthetic polymers. A polymer is a complex molecule made up of smaller, simpler molecules (monomers) that attach to form repeating structural units. Once a polymeric reaction has been catalyzed, it can be difficult to halt: the natural impulse to form polymeric chains is very strong, as are the resulting molecular bonds—and the glues based upon them. In the home and office, small quantities of C.A.s are useful for an almost infinite number of repairs such as mending broken pottery, repairing joints, and even holding together split fingernails. In industry, C.A.s have become important in construction, medicine, and dentistry.
