It is an oily material that can slow the drying of linseed oil producing a soft film. With time, asphaltum in dried oil films can result in the movement or disfigurement of the film as well as allligator cracks. Asphaltum was sold commercially as a transparent brown artist pigment under the name "bitumen." ]]></note></mads>
