In defect of a turn, proceed after the following manner, which is slow, yet safe, because in a turn the glasses, oftentimes waxing hot are broken by reason of the over great hast; and it is thus, make an iron or wooden receptacle fit to receive the glass bottle, which being covered about with linen, and put in, join both parts of the receptacle warily and softly, with the help of a screw, that the bottle be not broken, and that that instrument, or receptacle of the bottle being fastened to a form with the help of the screw, cannot be moved. Afterwards cause that another wooden instrument be made for the stopple (as for example, _A._ the stopple with its receptacle _B._ the bottle with its receptacle) that may be separated in the middle, and be again reunited with a screw after the putting in of the stopple, which being smeered over with the aforesaid mixture of _smiris_ and water, take the instrument with both hands, and put the stopple round about the neck of the bottle, and grind it round upon the other, as Wine Coopers are used to do in smoothing the taps; and that so long until the stopple be fit for the bottle; then reitereate the same labour with the earth _tripolis_, until it be compleated; and it will stop as well as a stopple made by the help of a turn [_See the second and third Figures before the fourth part._] After this manner also you must work those greater glass receivers of the first furnace, that without luting they may be closed. Stopples also of vials or Boltheads for fixation may be wrought after this manner, which in stead of luting may be put into the mouths of the vials, upon which are put caps of lead; by which means in case of necessity they may be lifted up, _viz._ in case the spirits by too strong a fire be stirred up and rarified, by reason of the danger the glasses are in to be broken, and may again fall down into the mouths of the bottles being pressed down with the leaden caps, and so stop close again. And this way of stopping is better then that which is done with cork, wax, sulphur, and other things: because in case the fire be not well governed, and by consequence an errour is committed, you may preserve your glasses by lifting up of the stopples, _viz._ when the spirits are too much stirred up. And although this be a better way of stopping than the other common way; yet that which follows is better then this, whereby the spirits are easily retained, the glasses being preserved, and without all danger of being broken. And it is thus, _viz._ get a glass pipe to be made crooked according to the figure set down, into the belly whereof is quicksilver to be put from half an ounce to an ounce, or thereabouts, and let this pipe which hath a belly be put into the vial containing the matter to be fixed (as for example. _A._ the pipe with a belly, _B._ is the vial, and again _C._ signifies the aforesaid leaden cap with the neck of the vial _D._) the joints
