Let there be made a vessell of verie choice earth, such as is verie cleane and verie
well kneaden, made vp with like paine and industrie as the Potters make vp theirs;
let it be of the thicknesse of a finger, or thereabout,
fashioned like an egge, and yet not like an egge when
it is whole, but when it is cut round away, almost to
the one halfe: it must be great, and conta
••ning much,
after the greatnesse and widenesse of the Copper ves∣sell:
and yet notwithstanding so great onely (especi∣ally
in respect of his height) as that it may agree with
the third and last loft of the furnace, and the wide∣nesse
euen and iumpe with the mouth of the furnace
wherein it must stand: and in like manner the bottome must beare such breadth, as
that it may be a little flatter than the space which is betwixt the two rods of yron,
made fast and set ouerthwart at the end of the second distance of the fu
••nace, to
the end that it may rest vpon them the more firmely. And therefore to doe well
herein, the furnace would be builded before that the vessell be made. When
there is need of a great fire to distill withall, then it is prouided, that the pot,
in this place, be not of earth, but of yron: as I my selfe haue seene at the Apothe∣caries.
This second vessell shall be of Copper, or of La••ten, and shaped also like vn••o
an egge, or a gourd, hauing a wide mouth, whereunto there must be fitted a long
or stretched-out necke, being at the least a foot in length, comming downe from
the head, by the which necke the vapours in the gourd shall rise vp into the said
head. This vessell shall hold twelue or fifteene pi••ts, or otherwise shall be made of
greatnesse answerable vnto the quantitie of the matter which you meane to distill,
which generally is (as wee will declare by and by) that for euerie pound of matter,
as of hearbes or seedes, &c. there be put into this vessell nine or tenne pound of wa∣ter.
Besides this, there must be such an agreement betwixt the greatnesse of this
Copper vessell and capacitie of the earthen vessell which standeth within the fur∣nace,
as that they may be free one of another some two or three fingers, for the fil∣ling
in of sand, as we will hereafter declare: And as concerning the height there∣of;
it, together with his head, must stand aboue that of earth a foot and a halfe
at the least.
The third vessell shall be the head, which shall be round aboue, and not sharp••-pointed,
to the end that the vapour arising out of it may not fall downe againe:
and it must be set about (as it were) with a little Stand, or Tub, wherein must be
put coole water, for the easier thickening and fixing of the vapours: at the one side
of this little Tub there shall be a spout, or pipe, which shall come out of the head,
and by this the Oyle shall drop downe into the vessell receiuing; on the other side
of this little Stand must be a tappe with a spiggot, and it must come from the ca∣pacitie
of the same, that so it may emptie it of the water which it holdeth when
it is become too hot. This head shall be ioyned with the orifice and throat of
the last afore-named vessell, by the meanes of a large and wide pipe, which shall
come dow••e from the head, and set it selfe in the mouth and throat of the said
Copper vessell verie closely, to the end that no vapours in rising may passe ou••
thereby anie way: and for the better perfecting of this inarticulation, there are
two edges or brimmes, that so they may the better ioyne together. This sh••••ke
may be called the necke of the bladder, by which the vapours shall rise vp into
the head.
The fourth vessell shall be the receiuing vessell, which shall receiue the Oyl••
distilled, and it must be of Glasse, because of the clearenesse and cle••••enesse of
the same.
This is the proportion and shape of the first sort of the vessels, and it is to distill
Oyles of hearbes, seedes, flowers, and so forth.
