■when it is purified, caft it into water, dry it, and then return it
into the pot to be refined over again, which will be in a little time j
then fee if the colour be to your fancy, and, according as you
find it, put in more or lefs of the former ingredients, and, hav-
ing thus perfected it, take it off and cake it: This Enamel will
be a good velvet-black for goldfmiths.
Another black Enamel. This fecond fort is diftinif. from the
other by the difference of the quantities and tinging ingre-
dients.
Take fix pounds of principal powder, two ounces of zafFer
prepared, two ounces of crocus martis prepared with vinegar,
two ounces of feretto of Spain ; pound and mix them very well
together, making an impalpable powder, and put it into your
glazed pot in the furnace to melt and purify; when it is well di-
gefted, caft it into water, dry it, and put it again into the pot,
where let it remain a while to refine; when it is for your pur-
pofe, take it off and cake it as ufual, and you will have a very
good and mofi convenient Enamel for the goldfmiths to fet in
colours and Enamel with.
Another black Enamel. Here is a third way of making the
velvet-black Enamel, much better and of a finer glofs than the
former,
To make which, take four pounds of principal powder, four
ounces of red tartar, two ounces of manganefe of Piedmont pre-
pared ; reduce thefe to a very fine powder, and put them into a
glazed pot bigger than ordinary, becaufe of the rifing of the me-
tal ; let it melt and digeft in the furnace, and caft it into water,
and when it is dry put it into the pot again, there to remain un-
til it melt and refine anew; when you find the colour proper
for your ufe, make it into cakes, and keep it for the goldfmiths
ufe.
To make purple-coloured Enamel. Take four pounds of prin-
cipal powder, add to this two ounces of manganefe of Piedmont,
prepared as for red Enamel; put thefe into a white glazed earthen
pot, allowing it room enough to bear with the ebullitions and
rifing of the metal ; when it is thoroughly melted, caft it into
water, dry it, and put it again into the pot to refine; then confi-
der whether it be well enough coloured, and accordingly make
it up into cakes and keep it for ufe as before.
Another purple Enamel. This is no lefs delicate than the
former, for all manner of goldfmirhs work.
Take fix pounds of the principal powder, three ounces of
manganefe of Piedmont prepared, fix ounces of fcales of copper
thrice calcined, as before prefcribed ; reduce thefe to an impal-
pable powder, and let them diffolve and refine in the white gla-
zed
