As a result old traditions of handicraft-men –important intangible cultural properties – are disappearing nowadays. This loss of knowledge was described for the first time at the beginning of the 20th century by a folklorist (Blau 1917) working in Bohemia. He mentioned that this knowledge starts to retreat to higher altitudes of forest lands, where the forests are the main focus of life. Blau (1917) described, that within a single farming house 12 different wood species were found in Carinthia and even 27 in Bohemia. These findings underline the high diversity of wood utilization in former times. By studying old books the description of properties and applications of various wood species can be found. The reasons for the selection of a species are usually not given. To bridge this gap of knowledge, we started to study historical wood utilization at collections of wooden artefacts like buildings, tools, machines, household appliances, furniture and so on. The aim is to set up a database of wooden goods where a description of the artefact itself, its geographic region, age and the wood species are linked. Groups of related applications mainly defined by different requirements are formed. These requirements can be directly linked to wood properties. First results show, that within the small region of the mountain Schneeberg, 32 different wood species including nine shrubs (mainly for highly specialised products as the rungs of a ladder) were in use. Understanding historical wood utilization will help to use our forests more efficiently – primarily in times of shortage of wood as raw material. 关键词:Historical wood utilization, wood quality, wood identification Michael Grabner, University of Natural Resources and Life Sciences, BOKU Vienna, Peter Jordan Strasse 82, A-1190 Vienna, Austria.   编辑:陈瑶

People of numerous crafts were ambitiously searching for curved and bended tree stems, branch-stem junctions of specific angles and root-stem junctions. They were aware of the disadvantages and the loss of strength by cutting out or bending wood for curved timber used in shipbuilding or in many other woodworks. The stiffness of branch-stem junctions for handles or other tools will never be reached by any other manmade wood junction. The high tensile strength one may want to achieve for curved designs will nowhere be higher than by using root-stem junctions. This used to be general knowledge since early times. Even Bronze Age tool handles were made out of branch-stem junctions. In Hallstatt, Austria, it was evident, that people working in the salt mines were carefully selecting the trees where the tool handles were cut out. Due to the process of industrialization and the wish for standardization and fast processing, hardly any wood deviating from a more or less straight design is used any more. This means, that just a small amount of the mechanical potential is used by humans. This might furthermore lead to a replacement of wood. It is important to realize that there is a specific application for every habitus, for every part of a tree and for every tree species. Being aware of this, you will get out the highest performance of wood for every application.   编辑:陈瑶
