Glues and adhesives have been used since ~200,000 years ago. A significant question about glues and adhesives in prehistoric contexts is exactly what level of holding strength do various blends have. A widely used glue in prehistory is pine pitch; whose ingredients are pine sap, ash, and a binder, such as dried grass. An experiment is presented here to determine how strong variations in concentrations of these ingredients affect holding strength. Six different variations of the glue were used,...
Identification of Adhesive on Bone-Handled Microblades from the Houtaomuga Site in Northeast China (2017)
With the emergence and development of composite tools in the Upper Paleolithic, adhesives became one of the most widely used materials by early human societies. Of particular interest is to know which animal/plant species were being exploited for glue manufacturing. The Houtaomuga site, located in northeast China, provides favorable materials for the identification of organic residues; and a few bone-handled microblades were collected from this site. In this study, we scraped micro adhesive...
