2. THE ART OF BURNISH GILDING.--Make a sizing by boiling the skins of
beaver and musk rats, (which may be readily procured at a hat
manufactory,) in water, till it is of sufficient strength that by
cooling it will become a stiff jelly; strain the liquor while warm, and
give your work one coat of it with a brush; when this is dry, add a
little fine whiting to the sizing, and give the work one coat of this.
Then add as much whiting as will work freely under the brush, and lay
on five or six coats of this, allowing each a sufficient time to dry.
Smooth the work by wetting it, and rubbing it with a piece of pumice
stone, which should be previously cut and fitted to the moulding or
other work that is to be gilt; afterward, when the work is dry, rub it
with some fine sand paper. Then take some burnish-gold-size (which is
composed of pipe-clay, plumbago, beef tallow and castile soap, but may
be easily procured ready made,) and dilute it with water till it is of
the consistence of very soft putty, and afterward with the above
mentioned sizing till it will flow freely from a brush, and give the
work three successive coats of this; when the last is dry, dip a
camel-hair pencil in a mixture of equal quantities of rum and water,
and with it wet a small part of the work, and immediately, while it is
flowing, lay on a leaf of gold, brushing it down with a very soft, flat
camel-hair brush, with which also, the leaf is usually conveyed from
the book to the sizing; proceed thus till the whole is gilt, and let it
dry. When the work is sufficiently dry to take a fair polish by
burnishing, (which can be only ascertained by applying the burnisher to
different parts of the work occasionally while it is drying,) rub over
the whole carefully with a flint burnisher, or with the tooth of a wolf
or dog, being fixed in a convenient handle, till the whole acquires a
brilliant polish, except such parts as are required to remain in a
rough-gilt state, which parts are usually flatted by a coat of thin
sizing. Such are the principal rules of the art of burnish gilding; but
as this business requires some variation of management, according to
the state of the weather and other circumstances, it may not be
expected that any person should become very expert in the art, without
the advantage of some experience and practice.
