Besides beech and oak, ash is one of the most important indigenous deciduous timbers. It is to be found in Europe, most frequently in the more northerly regions. For our purposes, the wood is briefly heated to a very high temperature. In this process it attains high resistance to water, the grain is accentuated and the wood takes on its brown colour. In order to preserve the naturalness of the surface, however, it is treated only with oil, not lacquered. This provides the wood with perfect protection against water and makes it particularly long-lasting.
