The way to colour Brass white. Diflblve two penny-weights
of filver in aqua-fortis, to which add as much powder of white
tartar as will abforb the water, and make it into halls, with
which rub any Brafs, and it will be as white as filver.
BRAZING, is the foldering or joining two pieces of iron,
&c. by means of thin plates or brafs, melted between the two
pieces to be joined.
If the work be very fine, as when the two leaves of broken
faws are to be brazed or joined together again, it is covered with
powdered borax moiftened with water, that may incorporate
with the brafs-duft, which is added to it, and the piece is ex-
pofed to the fire, without touching the coals, till the brafs be
obferved to run.
But, to braze with a ftill greater degree of delicacy, a folder
is made of brafs with a tenth part of tin ; or another, one-third
brafs and two-thirds filver ; or borax and rofin. But, in all
thefe manners of Brazing, care muff, be taken that the pieces be
joined clofe throughout j the folder only holding in thofe places
which touch.
