Pinite
Definition:
(n.) A compact granular cryptocrystalline mineral of a dull grayish or greenish white color. It is a hydrous alkaline silicate, and is derived from the alteration of other minerals, as iolite.
(n.) Any fossil wood which exhibits traces of having belonged to the Pine family.
(n.) A sweet white crystalline substance extracted from the gum of a species of pine (Pinus Lambertina). It is isomeric with, and resembles, quercite.
Example Sentences:
