=Charcoal Polishing.=--A method known as "charcoal polishing" is now
much used for producing the beautiful dead-black colour which seems to
have the density of ebony. Its invention is due to French
cabinet-makers. The woods used by them are particularly well adapted for
staining black or any other colour, limetree, beech, cherry, pear, soft
mahogany, or any wood of a close and compact grain being the woods
usually selected.

The first process is to give the work a coating of camphor dissolved in
water and made rather strong; this will soon soak into the wood, and
immediately afterwards another coat composed of sulphate of iron-water
with a few nut-galls added. These solutions in blending penetrate the
wood and give it an indelible tinge, and also prevent insects from
attacking it. After these coats are dry, rub the surface with a hard
brush (an old scrubbing-brush will do) the way of the grain, after which
rub the flat parts with natural stick charcoal, and the carved or
indented portions with powdered charcoal; the softest portion of the
charcoal only should be used, because if a single hard grain should be
applied it would seriously damage the surface. The workman should have
ready at the same time a preparation of linseed-oil and essence of
turpentine (linseed-oil one gill, and essence of turpentine one
teaspoonful), a portion of which should be freely taken up with a piece
of soft flannel and well rubbed into the work. These rubbings with the
preparation and charcoal several times will give the article of
furniture a beautiful dead-black colour and polish. This method of
