term
The stone that was used to extract pitch has different names locally and there were also differences in the extraction of pitch and the various products obtained. Pitch oil stones, pitch stones or greaves are also known as pitch stones or bacon stones. The next larger unit was the pitch furnace . The rock Pechstein , not related to the pitch extraction, takes its name after his often black color.
Pitch extraction
The stone was located directly in the forest, where the wood could be processed on site. Pine , spruce , fir and larch trees were suitable for the extraction of pitch using this method . The branches were piled in a pyramid shape on the stone and covered with spruce branches, earth and pieces of lawn. This kiln was then fired for at least a day. The wood, which did not burn due to lack of oxygen, gave off pitch ( wood tar ). This was led into a container through drains or channels that were cut into the pitch oil stones. The pitch oil was used as an ointment or, mixed with pork fat, as a car grease. Different types of pitch (see e.g. birch pitch ) or tar were won , as well as turpentine and charcoal .
