This water if it be abstracted from the salt several times, will turn white, almost like unto milk, and tast no more of sulphur, but be pleasant and sweet. It is is very good for the diseases of the lungs. Also it doth guild silver, being anoynted therewith, although not▪firmely, and by digestion it may be ripened and reduced into a better medicine.
The salt which remained in the glass body, urge with a strong fire, such as will make the sand, wherein the glass standeth red hot, and there will sublime a white salt into the limbeck, in taste almost like unto salt Armoniack, but in the the midst of the glass body, you will finde another, which is yellowish, of a mineral taste and very hot upon the tongue.
These sublimed salts, as well the white which did ascend into the limbeck, as the yellow, which remained in the glass body are good to be used in the plague, malignant feavers and other diseases, where sweating is required; for they doe mightily provoke sweating, they comfort and do cleanse the stomach, and cause sometimes gentle stools.
But what further may be done in Physick with it, I do not know yet.
In Alchymie it is also of use, which doth not belong to this place upon the remaining salt which did not sublime you may pour rain water, and dissolve it there in the glass body, (if it be whole still) else if it be broken, you may take out the salt dry, and dissolve and filtre and coagulate it againe, and there will be separated a great deal of saeces. This puri∣fied salt, which will look yellowish, melt in a covered cru∣cible, and it will turn quite blood red, and as hot as fire up∣on the tongue, which with fresh water you must dissolve a∣gain, and then filtre and coagulate; by which operation it will be made pure and clear, and the solution is quite green before it be coagulated, and as fiery as the red salt was before its dissolution.
This grass green solution being coagulated again into a red fiery salt, it may be melted again in a clean and strong cru∣cible, and it will be much more red and fiery.
