This is a colorless oil, and is in some instances used for delicate works where the length of time required for drying is no object. It is much celebrated in some old books, under the name of oil of pinks and oil of carnations, as erroneously translated from the French oeeillet, or olivet, a local name for the poppy in districts where its oil is employed as a substitute for that of the olive. It is, however, inferior in strength, tenacity and drying to linseed oil, although next to it in these respects, and, though it is of a paler color, and slower in changing, it becomes ultimately not so yellow, but nearly as brown and dusky, as linseed oil, and therefore is not preferred to it.

Nut Oil is the oil of walnuts, and is used in ornamental painting, as it is nearly colorless, and can be used with flake white and other delicate colors without the slightest danger of tingeing them.
