A New Light of Alchemy

3Nature is sometimes prevented from producing things so hard, since vapour, fatness, and salt are stained and mix with the earth’s places. Experience has therefore taught us to separate the pure from the impure. If you wish nature to be improved in action, dissolve whichever body you choose, separate and purify the heterogeneous thing that has acceded to nature, and join pure with pure, cooked with cooked, and raw with raw, according to nature’s weight rather than that of matter. Know that central nitrous salt takes no more earth than it needs, whether the earth is pure or impure. The fatness of water behaves differently: it is never obtained pure. Art purifies it through a twofold heat and joins it again.
