Archaeological Wood. Properties, Chemistry, and Preservation by Roger M. Rowell, R. James Barbour

By Roger M. Rowell, R. James Barbour

This can be the 1st booklet to mix chemistry with options of holding archaeological wooden. one of the themes mentioned in its 17 chapters are the chemical composition of wooden and alterations led to via the decay approach, biopredators, radiation curing, freeze-drying, chemical maintenance ideas, museum environments, the ethics of conservation, and price platforms for selecting one of the characteristics of wooden that may be preserved. This quantity presents realizing, from a systematic standpoint of archaeological wooden, its houses, its chemistry and its renovation.
