Philosophical and Chemical Experiences By the famous philosopher Lulle
Chap. I.
Where he is Teached, how to prepare the salt of the white and red Elixir Take, in the name of God, good sea salt because it is manufactured from the sea; take a good quantity and crush it very finely in a stone: then take Glass Cucurbites, and pour in your salt: take only well water, and let dissolve your salt in clear water; being dissolved, then distill by the filter; that is to say, hang a felt of wool or fabric, in the cucurbit; and let the other end hang in a another glass next to her, posed as if it were under her, she will fall into the water, that the felt or fabric will pull, and which must be clear as silver: and when water does drop more, look if it is very clear; if it is not, filter to into another glass, until it is clear or Crystalline: and when it is the case, put it in a pan of glass, put it on a sand fire, and let the water evaporate immediately, until it comes over it like a white salt: then take a pot of stone or pot of earth, as are the pots of drinks, and put in the water and the salt that remains, and leave on the said oven, and let the steam go, and when it begins to dry, mix it with a stick until it is very dry, otherwise it will be massed or blocked, and it will be well dried, finely ground in a stone mortar, as then put it in a melting crucible, and put it in an incandescent oven, or the said Furnace, which is an oven with which the jewelers enamel their rings: the oven being very hot, take the crucibles which are filled with salt, and put them in the oven, and leave them until they are incandescent, and be careful that they are not warmer on one side; if they are, turn them with a pair of ironer clamps: put a pot in the oven at once, which you can do for the best; and when this pot is at a glowing heat, take it out, and put it in another to be calcined.
