Glue

4000 BCE

While these days we have artificial man-made adhesives, simpler natural glues have been used for thousands of years. Ancient Egyptian carvings that are over 3,000 years old demonstrate the use of glue to stick veneer to sycamore, while many burial sites throughout Europe have 6,000-year-old pottery that has been repaired with plant sap and bark tar. The Ancient Romans even used beeswax glues to fill in the seams of their ships.
