Natural-based adhesives - 8,000 years and still going strong
Some of the earliest examples of man's recognition of the adhesive powers natural materials offered were discovered by archeologists near the Dead Sea in what is now Israel. Broken pottery shards seem to have been patched with what is believed to have been tree resins. In Egypt, paintings and drawings found in tombs show what appears to be the use of adhesive materials used in gluing wood objects. Artifacts from Egyptian tombs also reveal objects that appear to have been glued together using animal glues. Other archaeological evidence exists of the use of a number of natural materials as adhesives, including animal collagen, eggs, blood, tree resins, milk byproducts, grains and even the aforementioned beeswax.
