with water, and laid horizontally with fome fheets
of other paper under it. Where the rolling pi-int is
employed, the gum water, or fize muft be laid on it
with a proper brufh, immediately out of the pot or
veffel which contains it; but too copious a ufe muft
be avoided, for fear of fpreading it beyond the lines
of the defign or pattern. The fubfequent manage-
ment, of the gold, whether leaf or powder, muft be
the fame as in the foregoing kinds of gilding.
It rarely anfwers to ufe the leaf gold in this kind
of painting, nor even the true gold powder; but the
German powder, or that formed of the leaves called
Dutch gold, is moftly employed, and anfwers well
enough the purpole. The manufactures of the gilt
and marbled papers, have not been fo much cultivated
in our own country, as it were to be wifhed, fince
very great fums have been always annually paid,
both to Germany and Genoa, on this account.
Of gilding proper for letters of gold on paper, and
the embellifhments of manufcripts :—the moft eafy
and neat method of forming letters of gold on paper,
and for ornamets of writings, is by the gold armoniac,
as it was formerly called, the method of managing
which, is as follows:
t: Take gum ammoniacum and powder it, and
s: then diffolve it in water previoufjy impregnated
£i with a little gum arabic and fome juce of garlic:
c: the gum ammoniacum will not diffolve in water,
fo as to form a tranfparent fluid, but produces a
''• milky apnearance, from whence the mixture is
': called, in medicine, the lac ammoniacum. With
the lac ammoniacum thus prepared, draw, with a
