add five ounces more of flour of brimftone, pounding them well
together as before; then put the whole into crucibles, lute them,

then put it into a glazed earthen pan pretty deep, and pour on
it good fpirits of wine, that may fwim two inches above ; then
put fire to it, and, when it is burnt, you will have a very fine
Gold in an impalpable calx, well opened, which edulcorate with
warm water diftilled, and dry it gently.
Liquid Gold andfilver. Take five or fix leaves of Gold or
filver, and grind them with a ftiffgum lake water, and a good
quantity of fait, as fmall as you can ; then put it into a phial or
glazed vefiel, add to it as much fair water as may diftblve the ftiff
gum water ; then let it Itand four hours, that the Gold may fet-
tle ; decant off this water, and put in more, till the Gold is clean
wafhed ; then put more fair water to the Gold, a little fal ar-
moniac and common fait, digefting it clofe for four days ; then
put all into a piece of thin glover's leather, whofe grain is peeled
of]> and hang it up ; fo will the fai armoniac fret away, and the
Gold remain behind, which keep.
Or thus ; grind leaf Gold, with ftrong or thick gum water,
very fine ; and, while you are grinding it, add more thick gum.

then temper it with a little mercury fublimate, and a little dif-
folved gum to bind it to the (hell ; fhake it, and fpread the Gold
about the fides thereof, that it may be all of one colour and fine-
nefs, which ufe with fair water, as you do other colours.
To burnljh Gold. Do the fame as to liquid filver. Take
gum lake and diflblve it into a ftifF water, then grind a blade or
two of faffron with it, and you will have a fair Gold ; when
you have laid it and it is thoroughly dry, burnifh it with a dog's
tooth.
Or thus; having written what you had a mind with your pen
and pencil, cut the leaf Gold or filver into pieces, according to
the fize ; take it up with a feather or cotton, &c. and lay it upon
the writing or drawing, which prefs down with a piece of wool,
and, being dry, burnilh it.
To make a very fine polijhed Gold. The woods you would
gild muft be very fmooth ; and, to render them the fmoother, it
will be proper to pafs fea dog's (kin over them.
Then fize it over with a fturT or fize made of the cuttings of
white leather gloves, fee SIZE ; and, when it is thoroughly dry,
Jay on nine or ten layers of white.
When this is perfectly dry, ufe your fhave-grafs, that you may
