in the inftance of papier mache. than on metals,
continue (till to reject it. On which account the
boxes of their manufacture are, with regard to the
wear, much better than the French.

The laying on the colours with varnifh inftead of
gum water, is alfo another variation from the me-
thod of japanning formerly practifed. But the much
greater lfrength of the work, where they are laid
on in varnifh or oil, has occasioned this way to be
exploded, with the greateft reafon in all regular
manufactures. However, they who may praclife ja-
panning on cabinets, or other fuch pieces, as are not
expofed to much wear or violence, for their amufe-
ment only, and confequently may not find it worth,
their while to encumber themfelves with the prepa-
rations neceffary for the other methods, may paint
with water colours on an undercoat laid on the wood,
or other fubftance, of which the piece to be japanned
is formed : and then finifh with the proper coats of
varnifh, according to the methods below taught. If
the colours are tempered with the ftrongelt ifmglafs
lize and honev, inftead of gum water, and laid on
very flat and even, the work will not be much in-
ferior in appearance to that done by the other me-
thod ;. and will laft as long as the common old japan
work, except the beft kinds of the true japan.

It is practifed likewife, in imitation of what is
fometimes done in the Indian work, to paint with
water colours on grounds of gold ; in which cafe
the ifinglafs iize, witli iugar-cancly or honey, as
above directed, is the beft vehicle.

Imitations are alfo made of japan work, by colour-
ing prints, gluing them to woodwork, and then giv-
ing them a mining appearance, by the ufe of fome
white varnifh.
