This comprehensive practical guide to the identification of vegetable fibres will be of use to forensic scientists, archaeologists, conservators of antiquities, botanists and any others who need to identify plant fibres. It presents the microscopical characteristics of ten of the most widely used commercial fibres (Flax, Hemp, Sunn hemp, Ramie, Jute, Kenaf, Roselle, Sisal, Abaca [Manilla hemp]), and describes in detail features, which are useful for identifying fibre cells. There are tables, photomicrographs and line drawings to enhance the text. An account of the cultivation and extraction of each of the fibres and details of the methods of specimen preparation are also include. N° de réf. du libraire AAS9781873132616
Synopsis : It is often possible to identify fragments of plants by studying their microscopical characteristics. The recognition of a single feature very rarely establishes the plant's identity; more often, it is necessary to recognize a unique combination of characteris tics. For plant identification, the most valuable characteristics are those least likely to be affected by changes in environment; if the feature is uncommon as well as stable, it is even more useful. Good descriptions of the anatomy of plants are invaluable. For example, The Identifi cation of Hardwoods (Brazier and Franklin, 1961), together with its punched card key, is an excellent book which is useful in practice. Characters describing the sc1erenchyma account for only three places in this key. Using only these characters, it would be impossible to identify a timber. Is it possible then, to identify a species given only sc1erenchyma in the form of a commercial fibre? If it is possible, it is not easy. Although, for many purposes, plant fibres are being replaced by man-made fibres, vegetable fibres are still used, particularly in sacking and cordage and in some indus trial materials. Articles which must be examined in a forensic science laboratory are not always of recent manufacture and archaeologists and historians are interested in older materials. Therefore, it is still necessary for many workers to identify the plant species from which fibres have been extracted.
Synopsis: This book should be of interest to those concerned with forensic science, conservationists in art and archaeology, textile and paper technologists and botanists.
