It consists in four things, Calcination, Solution, Filtration, Coagulation.
Burn the matter you would make salt of into white ashes, and berein sometimes you must have a care 〈◊〉〈◊〉 by too hasty burning they run to glass; then with 〈◊〉〈◊〉 water make the ashes into ly to draw out the Salt, fil∣ter the Ly and boyl it in an 〈◊〉〈◊〉 vessel by a 〈◊◊〉〈◊◊〉, that the water may be exhaled and the Salt left; which Solution, Filtration, and Coagulation being re∣peated certain times it will be free from all impurity, and be very white.
