Abstract
Characteristics of wood shrinkage, water content and degradation are discussed in an effort to relate the capabilities of the wood technologist with the needs of the archaeological conservator. Controlled drying rather than impregnation with poly(ethylene glycol) is suggested as a superior method for conserving artifacts of essentially sound wood. Preservation of color in archaeological specimens is discussed. Freeze-drying is discussed, as well as the effects of polymerized oil saturation of hardwood artifacts. The phenomenon of permeability of various woods and various portions of the same wood are discussed. Use of ultrasonic energy is suggested as a means of facilitating cleaning and impregnation. Damage to waterlogged artifacts by anaerobic bacteria and/or chemical decay before excavation is discussed. Polymerization of methyl methacrylate and other resins is discussed. Identification of the wood of which an artifact is made is called for. Anatomies of bark and wood are contrasted. Many of the specialties of the wood technologists can be used by archaeological conservators. Sources of information and selected references are given. -- AATA
