Method for extracting oil-containing consolidation agent from e.g. wood sculpture, involves contacting organic solvent i.e. cyclic ether, with wood object, so that oil-containing consolidation agent in object is extracted by solvent
The method involves transferring an organic solvent i.e. cyclic ether, into gaseous phase. The organic solvent is in contact with a wood object, so that oil-containing consolidation agent in the wood object is released and extracted by the organic solvent. Production of negative pressure at boiling point of the organic solvent is lowered to or below ambient temperature so that the organic solvent is transferred into the gaseous phase. An independent claim is also included for a device for extracting oil-containing consolidation agent from a wood object.
