Niter Quotes (1 quote)
What, then, shall we say about the receipts of alchemy, and about the diversity of its vessels and instruments? These are furnaces, glasses, jars, waters, oils, limes, sulphurs, salts, saltpeters, alums, vitriols, chrysocollae, copper greens, atraments, auripigments, fel vitri, ceruse, red earth, thucia, wax, lutum sapientiae, pounded glass, verdigris, soot, crocus of Mars, soap, crystal, arsenic, antimony, minium, elixir, lazarium, gold leaf salt niter, sal ammoniac, calamine stone, magnesia, bolus armenus, and many other things. Then, again, concerning herbs, roots, seeds, woods, stones, animals, worms, bone dust, snail shells, other shells, and pitch. These and the like, whereof there are some very farfetched in alchemy, are mere incumbrances of work; since even if Sol and Luna [gold and silver] could be made by them they rather hinder and delay than further ones purpose.
