Bitumen

is a viscous liquid, or a solid, which consists largely of hydrocarbons and their derivatives. It softens gradually on volatile. It occurs naturally as bitumen and, in conjunction with mineral matter, as asphalt. It is also produced as a by-product of petroleum refining. It is used as a water-proofing and binding agent.

Bitumen

A naturally-occurring, non-drying, tarry substance used in paint mixtures, especially to enrich the appearance of dark tones. Bitumen became very popular as a paint additive in the late eighteenth century and early nineteenth. However, because it does not dry it eventually causes often severe darkening and cracking of the paint. This can be seen in...
