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:
“It was a tall young oysterman lived by the river-side,
His shop was just upon the bank, his boat was on the tide;
The daughter of a fisherman, that was so straight and slim,
Lived over on the other bank, right opposite to him.”
—Oliver Wendell Holmes, Sr. (1809–1894)
“Oh Gull of my childhood,
cry over my window over and over, take me back,
oh harbors of oil and cunners, teach me to laugh
and cry again that way that was the good bargain
of youth....”
—Anne Sexton (1928–1974)
