tow and rags. This gives a beautiful chocolate colour to the wood.
Numerous compositions are in the market for filling the pores of wood,
and in this connection particular attention has been given to walnut,
for the reason that this wood is used in large quantities in the
furniture industry, and is nearly, if not quite, as porous as any other
of the woods used.
A variety of walnut fillings have been recommended to the trade in order
to meet the demand consequent upon the different grades of finish and
the method of obtaining the finish, so that it would be difficult to
pronounce as to the superiority of any one filling for general purposes.
In treating this subject, attention should be given to the necessities
for the use of filling, so that each one may determine for himself the
kind of composition best adapted for the work in hand, and the best
method of applying it.
=Finishing.=--Having described the methods of making and applying the
"fillings," we will now describe the mode of finishing, and begin with
the "dead-oil finish." We can remember when a satisfactory oil-finish
was produced either with a good quality of japan or a fair quality of
spirits. These materials are recommended to be used by inexperienced
workmen and those not familiar with the mixing of the various grades of
japan and varnish with oil, turpentine, benzine, etc. This method of
oil-finish, too, is scarcely inferior to the shellac or spirit-varnish
method, and it is cheaper. When the best finish is desired, a sufficient
number of coats to fill the pores of wood to a level are required, and
then the whole surface should be subjected to the rubbing process. The
use of these fillers provides an oil-finish in a simplified form for
those who are not aware of the difference between hard and soft gum
compositions as a base for rubbing. In fact, the rubbing process
constitutes a fine oil-finish, and requires a hard gum, whether it be of
japan, varnish, or shellac.
The use of varnish or its substitute as a filler and finish is more
frequent than the use of shellac, and for cheap work it is equally good.
The surface produced by a hard gum composition must be smooth and dead,
or but slightly glossed, so as to admit of the pores being filled full
or to a level. It may
