Over the years, preservation methods have provided organic artifacts—especially water-logged materials—with a limited lifespan. Working with Dow Corning Corporation, Texas A&M's Archaeological Preservation Research Lab, and the Conservation Research Lab, Smith and his colleagues set out to develop a series of techniques that would yield successful and affordable treatment strategies for organic artifacts without sacrificing important information. Here, Smith provides step-by-step instructions for the conservation of small organic artifacts and then examines some of the mechanical techniques used to process various organic materials from marine and land sites.
