Tall oil, also called "liquid rosin" or tallol, is a viscous yellow-black odorous liquid obtained as a by-product of the Kraft process of wood pulp manufacture when pulping mainly coniferous trees. The name originated as an anglicization of the Swedish "tallolja" ("pine oil"). Tall oil is the third largest chemical by-product in a Kraft mill after lignin and hemicellulose; the yield of crude tall oil from the process is in the range of 30 – 50 kg / ton pulp. It may contribute to 1.0 - 1.5% of the mill's revenue if not used internally.

Famous quotes containing the words tall and/or oil:
“Do you know how poetry started? I always think that it started when a cave boy came running back to the cave, through the tall grass, shouting as he ran, “Wolf, wolf,” and there was no wolf. His baboon-like parents, great sticklers for the truth, gave him a hiding, no doubt, but poetry had been born—the tall story had been born in the tall grass.”
—Vladimir Nabokov (1899–1977)
“His education lay like a film of white oil on the black lake of his barbarian consciousness. For this reason, the things he said were hardly interesting at all. Only what he was.”
—D.H. (David Herbert)
