Asphaltum Varnish for Woodworking

¶ Asphaltum Varnishes. This is not considered a resin varnish. Asphaltum is a natural product, also called bitumen, found in many places the world over, Syria, Cuba, Trinidad, Utah, Albania, and Barbados. Pure asphaltum from Utah is called Gilsonite while the bituminous limestone found in Texas is known as litho-carbon. Asphaltum is a constituent of both limestone and petroleum. It is insoluble in water and alcohol but may be dissolved readily with turpentine and naphtha.
