- n. Lead monoxide; a yellowish red substance, obtained as an amorphous powder, or crystallized in fine scales, by heating lead moderately in a current of air or by calcining lead nitrate or carbonate.

- n. The yellow or reddish protoxid of lead (PbO) partially fused.
The ore was melted and converted into ingots, the silver separated and refined, and litharge, red lead and shot manufactured.
Having fomented with plenty of hot water, boil in the water certain of the fragrant medicines, add pounded tamarisk, roasted litharge and galls, and pour on them white wine, and oil, and the grease of a goose, pounding all together.
Send to the first apothecary of your town for some litharge; throw into it one grain of the red powder which
This man had previously bought up all the litharge from the apothecaries of Sedan and got it resold after mixing it with a few ounces of gold.
When he had consumed all the litharge in Sedan he made no more gold, nor ever more saw his philosopher or his forty thousand crowns.
In particular, it seemed the perfect alternative to lead monoxide (PbO, litharge), the white pigment in those "lead-based" paints you hear about.
The latter, however, contains a remnant of litharge, possibly showing that the old Egyptians worked the silver, which may have been supplied by the Colorado quartz.
In the latter experiment also, the culot came away without the litharge, which almost always contains traces of silver and antimony.
So it is, too, with inanimate things; for of these, too, some are really silver and others gold, while others are not and merely seem to be such to our sense; e.g. things made of litharge and tin seem to be of silver, while those made of yellow metal look golden.
For lead oxide, PbO, the choices are red lead, white lead or litharge.
