by the lead with which the pieces are to be joined
together. The diftribution being made, they mark
all the glaffes as well as papers, that they may be
known again: which done, applying every part of
the defign upon the glafs intended for it, they copy
or transfer, the defign upon this glafs with the black
colour diluted in gum water, by tracing and follow-
ing all the lines and ftrokes as they appear through
the glafs, with the point of a pencil.
When thefe ftrokes are well dried, which will
happen in about two days, the work being only in
black and white, they give a flight wafh over with
urine, gum arabic, and a little black : and repeat it
feveral times, according as the {hades are defired to
be heightened, with this precaution, never to apply
a new wafh till the former is fufficiently dried.
This done, the lights and rifings are given by
rubbing ofF the colour in the refpeclive places with
a wooden point, or the handle of a pencil.
As to the other colours abovementioned, they are
ufed with gum water, much as in painting in mi-
niature ; taking care to apply them lightly for fear
of effacing the outlines of the defign; or even, for
the greater' fecuritv, to apply them on the other
fide ; efpecially yellow, which is very pernicious to
the other colours, by blending therewith. And
here too, as in pieces of black and white, particu-
lar regard muft always be had not to lay colour on
colour, or lay on a new lay, till fuch time as the
former are well dried.
It may be added, that the yellow is the only co-
lour that penetrates through the glafs, and incorpo-
rates therewith by the fire; the reft, and particu-
larly the blue, which is very difficult to ufe, re-
