Of the Art of Diſtillation.
Book.1.
- When you put water into a ſeething Balneum wherein there are glaſſes, let it be hot or elſe thou wilt endanger the breaking or the glaſſes.
- When thou takeſt any earthen, or glaſſe veſſell from the fire, expoſe it not to the cold aire too ſuddenly for feare it ſhould break.
- If thou wouldeſt have a Balneum as hot as aſhes,' put ſand or ſawduſt into it, that the heat of the water may be therewith kept in, and made more intenſe.
- If you would make a heat with horſe-dung, the manner is this, viz. make a hole in the ground, then lay one courſe of horſe-dung a foot thick, then a courſe of unſlaked lime halfe a foot thick, then another of dung, as before, then let in your veſſell, and lay round it lime, and horſe-dung mixt together; preſſe it downe very hard; you muſt ſprinkle it every other day with water, and when it ceaſeth to be hot, then take it out and put in more.
- Note that alwayes ſand or aſhes muſt be well ſifted, for otherwiſe a coal or ſtone therein may break your glaſſe.
- The time for putrefaction of things is various, for if the thing to be putrefied be vegetables and green, leſſe time is required, if dry, a longer, if Minerals the longeſt of all. Thus much note,that|things are ſooner putrefied in cloudy weather then in faire.
- If thou wouldeſt keep vegetables freſh and green all the year, gather them in a dry day, and put them into an earthen veſſell, which you muſt ſtop cloſe, and ſet in a cold place: and they will as ſaith Glauberus keep freſh a whole year.15. Doe
