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,

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.
