I thought this was fascinating find about prehistoric glue and coloring (58,000 years ago! ): http://news.discovery.com/archaeology/p ... ctory.html

" Ochre is derived from naturally tinted clay that contains mineral oxides. In addition to coloring objects, it makes a compound adhesive when mixed with other ingredients, such as plant gum and animal fat.

"This glue would have attached stone spear or arrowheads to hafts, or blades to handles for cutting tools," Wadley explained.
