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." ]]></termNote><termCreatedDate>2026-03-30 20:57:56</termCreatedDate><relation><relationType>UF</relationType><termId>31437439</termId><termName>asphalt</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31437440</termId><termName>bitumen</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31411037</termId><termName>organic brown pigment</termName><termType>PT</termType></relation><relation><relationType>NT</relationType><termId>31456237</termId><termName>mummy</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31339958</termId><termName>bitumen</termName><termType>PT</termType></relation></term>  </Zthes>
