The maner of cutting your Glasses fitte for your purpose.

NOwe the easie way•• of cutting the neckes of diuers Glas∣ses, when néede requyreth, with the apt Instrumentes ser∣uing to that vse, shall hereafter appeare. First with that stone (which the Glasiers vse) being set into some handle, drawe about the necke of the Glasse, in the same place where you couet to breake it of. After the Instrument formed, hauing thrée or foure edges, accor∣ding

to the fi∣gure here des∣cribed) and the same made glowing hote, worke about the raced place vnto the time it be through hote. After by dypping your finger in water, and letting a droppe or two fall, the Glasse incontinent will cracke in the sayde place marked: and drawing after that instrument (which we haue a∣boue demonstrated) rounde about, you may lightly breake of the p••ece without daunger to the Glasse. The lyke of this haue I knowne to be wrought with a poynted Diamonde set in a Ring: but a waxed thréede was fastened about that place, by which (the Diamonde guided) shoulde runne, for the strayghter and euener racing of the Glasse, which done in such order, and the place heated hote rounde about with the flame of a waxe Candle, or o∣ther Candle, if a man will, was sodainlye cracked through the falling of a droppe or two of colde water, on the place marked. Another more easie waye to cut Glasse, haue I knowne experi∣enced with a bygge Wyer wreathed rounde at the one ende (like to a Ring) which heated glowing hote, and turned often rounde on the place marked, caused the Glasse (through his heating) by a droppe or two of colde water falling on it, to cracke about the sayde raced place. Some vse to breake off the necks of Retorts,

with a double waxed thréede twisted hard, and made in the forme of a Ring, which put harde on the necke, they heate the same rounde about with the flame of a waxe Candle, and by pouring a drop or two of water on the place, the Glasse is caused to cracke.

And some vse other Instruments lyke to those before descry∣bed, which heated glowynge hote, after they drawe sundrye tymes about the place of the Glasse raced, and doe the rest aboue taught.

If you couet to seale vppe or shutte close the mouthes of nar∣rowe necked Glasses, that no vapours or spirites maye breath forth, and that these maye appeare to be whole on euerye part, then prepare a little Furnace (lyke to this here descrybed) in

[illustration]

whose bottome let a Grate of Iron bee cout∣ched, wyth a hoale made in the side aboue the Grate, to thruste in the necke of the Glasse, and ret∣ching vp to the top of the Fur∣nace, set a strong payre of Tonges, and broade at the ende, which done, and the necke of the Glasse made hote, wryng with the glowing Tonges the Glasse togither, then sweating by occasion of the heate, which shall so be vnited at the top, as the same there were whole, or that it séemed lyke as it were closed togither in the Glasse makers shoppe.
