A, The crooked pipe.
B, The Glaſſe-body.
Or upon the top of a Glaſſe-ſtopple there may be
faſtened ſome lead, that if the ſpirit be too ſtrong it will onely heave up the Stopple and let it fall down again.
C, The Glaſſe-ſtopple with lead on the top.
D, The mouth of the veſſell itſelf.
Now the way to nip up a glaſſe, or ſeal it up Hermetically
is after this manner.
PUt what matter you pleaſe into a bolt head with a long neck or pipe, put this pipe through a pan that hath a little hole made in the bottome thereof, that the top of it may be three or four inches above the pan, cloſe up the hole round about the pipe with clay, then put coals in the pan and kindle firſt thoſe that are furtheſt off from the pipe that the heat may come by degrees to the pipe (for otherwiſe a ſuddain heat will break it) when the pipe is hot, blow the coals about it til it melt, then with a pair of ſheares cut it off where it is melted, and then with a pair of tongs cloſe it together.
Note that after you have cloſed it you muſt put the burning
coals upon the top thereof, and let it thus ſtand till all
be cold
