and lay it over the place to be foldered, which muft be firft fit-
ted and bound together with wire, as occafion requires ; then take
borax in powder, and temper it like pap, and lay it upon the
Solder, letting it dry ; then cover it with quick coals and blow,
and it will run immediately ; take it prefently out of the fire, and
it is done.
Note i. That if a thing is to be foldered in two places, which
cannot be well done at one time, you muft firft Solder with the
hard Solder, and then with the foft; for, if it be firft done with
the foft, it will unfolder again before the other is foldered.
2. That, if you would not have your Solder run about the
piece that is to be foldered, rub thofe places over with chalk.
