iron or copper-plate, or rather piece which is to be
japanned ; and then lay vermillion tempered with
fhell-lac varnifh, or with drying oil, diluted with
oil of turpentine, very thinly, on the places intend-
ed to imitate the more tranfparent parts of rhe tor-
toife fhell. When the vermillion is dry, brufh over
the whole with the black varnifh, tempered to a
due confiftence with oil of turpentine ; and when
it is fet and firm, put the work into a ftove, where
it may undergo a very ftrong heat, and it muft be
continued a confiderable time, if even three weeks
or a month, it will be the better.
This was given, among other recipes by Kunckel,
but appears to have been neglected till it was re-

factures, where it was not only the ground of fnuff-
boxes, dreffing-boxes, and other fuch like leffer
pieces, but of thofe beautiful tea-waiters, which,
have been fo juftly efteemed and admired in feveral
parts of Europe where they have been fent. This
ground may be decorated with painting and gilding,
in the fame manner as any other varnifhed furface,
which had heft be done after the ground has been
duly hardened by the hot ftove ; but it is well to
