mixture, going over it fo often till the filver feems to be changed
to a gold-like colour.
13. And, laftly, take care'that your varnifh be not too thick
and high-coloured with the fanguis and gamboge ; but rather
heighten it by degrees, left the filver be too high-coloured before
it has had a fufficient body of varnifh : Let it ftand to dry fix or
feven days; then polifh and clear it up as before directed.
Japanning with gold fize. i. When your work is wrought,
and you would decypher on it, draw the gold fize all over that
part, and that part only, which you intend to gild or adorn with
gold, omitting thofe places where you intend to lay your metals
and other colours, as filver, copper, brafs, &c.
2. The fize being thus wrought for the gold, let it remain till
it is fo dry, that, when you put your finder upon it, it muft be
glutinous and clammy, and ftick a little; but not fo moift that
the leaft particle of it fhould come off with your fingers, but
that it may be much like to thick glue when it is half dry.
3. When it is in this temper, it is the very nick of time when
the gold is to be applied ; then take a piece of foft wafh-leather,
or the like, and wrap about your fore finger; dip it in your gold
duft, and rub it where your gold fize is laid, for it will ftick
on the fize and no where elfe.
4. It any gold duft lie fcattered about your work, brufh it all
away into your paper, in which your gold is, witl>a fine varniih-
ing brufh which has not been ufed.
5. Then with your pencil draw that part with gold fize alfo
which is defigned for your copper, and let it dry, as has been
directed for the former; and then cover it with copper duft, af-
ter the fame manner as you did with the gold duft.
6. Having done this, lay on your filver fize ; and when it Is
dry, as before, lay on your filver duft, as you did the two former.
7. But this is always to be obferved, that the metalline co-
lours are to be laid fucceffivelv one after another, letting each be
covered and thoroughly dry before you enter upon a diftincl
colour.
8. After all thefe, the other colours, which are not metal-
line, are to be laid on with gum water, referving the rocks, &c.
for the laft part of the work.
9. If you have mixed more gold fize than you have occafion
for at one time, or if you are hindered from finifhing it in one
day, you will obferve that your fize, in five or fix hours time,
will have a fkin upon it; in order to this, put the pencils into
a gallipot of water, and pour fair water over your pot of gold
fize ; and, if your fize fhould grow too thick, you may thin it
w7ith Venice turpentine ; but you are to take notice, that doing
this oftener than once will fpoil the fize.
