Another way, but more beautiful. Inftead ofindigo, fteep Dutch
turnfole for a day or two,in water, then {train it through a cloth
from the dregs ; grind and mix this water with the yolk of an
egg, lay this on your filver, then with turnfole ground with turn-
fole water draw with a pencil what lines or figures you think fit,
which you may fhadow and hatch in the proper places, which
heighten in discovering the filver, as before directed ; then var-
nifh the work.

To make the ground of a purple colour Boil brafil in lime wa-
ter, and mix with turnfole water. This will not 'aft fo well as
that done with indigo, becaufe the turnfole in time is apt to turn
red, and will (lain the filver ; therefore, before you varnifh, lay
upon it the white of an egg beaten into glair, which will render
it much more durable, and admirably beautiful.

To inrich carved worky or any fort of W00DEM work. The
Wooden work, whether picture frames, or other things, cover
with burnifhed filver, as taught under the article GILDING, he.
and having made fome vellum glue or parchment glue, boiled to
a thick jelly, ftrain it through a cloth ; let it ftand to fettle, and
then ftrain it again ; then with this glue give one laving upon
your work with a foft brufh ; if it be not enough, give a fecond,
and then varnifh it. But before you varnifh., if you have a mind
fo to do, you may paint flowers, fruits, leaves, or birds, in water
colours, and in their proper colours; and varnifh them, having
firft laid them over with glue.

Note, you may mix, with your glue, either milk, or foap of
Alicant.

Hoiv to embellljh a Wooden frame w'ah green leaves. Take
indigo, a little orpiment ground with water, inclining towards a
greenifh brown, mixing, with about half a pint of your colour,
the quantity of a mufcle-fhell of the yolk of eggs, and as much
fize as is requifite to make it.

Having firft laid on your white in the fame manner, as if you
were to gild it with burnifhed gold ; then paint the friezes of
your frame with this brown colour, leaving the mouldings un-
touched, which you are before to gild with burnifhed gold.

Having thus prepared your work, you muff, either by pounc-
ing, or other ways, draw what figures you pleafe ; then with in-
digo alone, ground with water, a little fize, and a drop of the
yolk of an egg, draw your figures or leaves, and fhadow them ;
and in fhadowing fweeten, heightening them with green, viz.
you muft take orpiment, well ground with the greenifh brown*
wherewith you laid the firft layer upon your frame ; then heigh-
ten it with orpiment alone, ground with water and fize, and a
little drop of the yolk of an egg among your colour?, becaufe it
