BLEND, n. [Ger. blenden, to bind; blende, a blind or skreen.]

An ore of zink, called also mock-lead, false galena, and black-jack. Its color is mostly yellow, brown and black. There are several varieties, but in general, this ore contains more than half its weight of sink, about one fourth sulphur, and usually a small portion of iron. In chimical language, it is a sulphuret of zink. – Fourcroy. Cleaveland. Thomson.
