Glue is a liquid adhesive, used to stick two items together. A little kid may use Elmer’s glue to decorate an art project, and you may use Krazy Glue to repair a mug’s broken handle. Whatever the case, you hope the glue sticks.
Most glue comes in a squeeze bottle and is used in small drips and lines to paste one material to another, but some glue comes in solid sticks that aren’t as messy. When you stick one thing to another with glue, you glueit. The Old French source of glue is glu, from the Latin gluten, which means both “glue” and “beeswax.”
The use of adhesives offers many advantages over binding techniques such as sewing, mechanical fastening, thermal bonding, etc.
These include the ability to bind different materials together, to distribute stress more efficiently across the joint, the cost effectiveness of an easily mechanized process, an improvement in aesthetic design, and increased design flexibility. Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects
