Interesting Facts about Glue

  • Earliest known example of humanity using natural glues comes from 200,000 years ago. Our ancestor in old Italy used birch-bark-tar to bind stones together.
  • Today, industry of adhesives moves more than 11 billion dollars just in United States.
  • Prehistoric hunters used natural glue to bind stone arrowheads or axe stones to wood.
  • One square inch of super glue can hold around one ton.
  • Adhesives can be separated into several groups – adhesives by origin (natural of synthetic), and adhesives by types of reactiveness (drying, pressure sensitive, contact, hot…).
  • First written record of glue comes from the Ancient Egypt. One of the earliest examples are hieroglyphs that shown casket of Pharaoh Tutankhamun that was glued together with compound made from animals.
  • Glue was very commonly used in Europe during Ancient Rome, medieval times and Renaissance.
  • First commercial glue plant was established in 1690 in Holland.
  • Glues ere so effective because they come in contact with surfaces while they are in liquid form. This enables them to fill up even microscopic spores, and then harden to a strong solid state.
