Earliest usage of glue adhesives

November 28th, 2013 | by heritagedaily


The earliest use of adhesives was discovered in Italy. At this site, two stone flakes partially covered with birch-bark-tar and a third uncovered stone from the Middle Pleistocene era (circa 200,000 years ago) were found. This is thought to be the oldest discovered human use of tar hafted stones.
