A yellowish powdery mixture of zinc and lead oxides collects on the lead; it is skimmed off and sold as paint.
Plucking one from the bush, she rolled the berry in her hand, removing the powdery haze from its surface.
It has in general one value for the powdery metal as obtained by reduction of the oxide in hydrogen below the melting point of the metal, another for the metal in the state which it assumes spontaneously on freezing, and this latter value, in general, is modified by hammering, rolling, drawing, &c. These mechanical operations do not necessarily add to the density; stamping, it is true, does so necessarily, but rolling or drawing occasionally causes a diminution of the density.
These Arka-tagh mountains are built up, at all events superficially, of sand and powdery, finely sifted disintegrated material.
