mel, remaining fmooth in this condition, ferves for a field to place
all your other colours on, as we will farther difcourfe of in the
art of portraying.
Oil of fpike is ufed for difTolving thick and opaque Enamel be-
fore it can be applied ; for the tranfparent, you need ufe nothing
but fair water, as we {hall fhevv anon ; and then it is couched
flat and bordered with the metal, and fometimes we do not bor-
der at all, the field being Enamel; but this is troublefome, be-
caufe the limpid Enamels, as they melt, often mix, and fo con-
found the colours, which conftantly happens when the pieces are
fmall.
Red Enamels are not fo, unlefs by chance, and come gene-
rally yellowifh out of the lire ; as foon as it is applied to the gold,
it alters the colour ; one may foon bring it to a perfect red Ena-
mel, by turning it at the mouth of your furnace, when you are
taking it out from the fire; and then it is that the workmen fay
they make it red, and give it its complete colour.
Gold, as we have already faid, admits of all forts of Enamel,
clear or opaque, bright purple excepted, which is altered by the
yellow colour of the gold, and does not take fo good efFedt there
as on filver. on which it ought {fill to be ufed. The way of
working every fort of Enamel is alike.
To Enamel on filver. We have already taken notice that fil-
ver agrees not with all forts of Enamel, as gold. We repeat it
here again, to prevent the ufe of any but fuch as ferve to produce
perfect and agreeable effects.
You are to make leaft ufe of white Enamel on filver, becaufe
there it becomes yellowifh and unpleafing ; but nothing can fuit
better with it than bright purple, green, blue, and egmarine,
becaufe the whitenefs of the filver is then clearly eminent, and
gives its juft fplendor.
The work and manner of enamelling on filver is noway dif-
ferent from that of gold, in forging the plates evenly to prepare
them for the Enamel; you may make ufe of white on the under
fide, firice the Enamel there ferves only to qualify the rifings and
chfturbings of the metal in the furnace, which would caufe un-
evennefs, or difagreements in the furface, and prevent its be-
coming juft and handfome.
We need not repeat again that way of placing the Enamel on
your plates of gold or fib er, and fo to put them into your little
reverberatory furnace, fpoken of before, to melt, and as foon as
poiifhed to be taken from the fire.
To Enamel on copper. Though we have before touched upon
the way of enameling on copper, yet, left the reader fhould too
flightly apprehend it, we (hall therefore treat of it here to avoid
imperfection.
