and the manner in which the same is to be performed, is particularly described
and ascertained by the following description thereof (that is to say):-
6 gallons of linseed oil, 1½ pounds of rosin, and 4 pounds of red lead,
litharge, or any other substance usually known under the denomination of
dryers, are to be boiled together till they acquire sufficient consistence to
adhere to the finger in strings when cooled upon a bit of glass or otherwise;
it is then to be removed from the fire, and, when sufficiently cooled, thinned
to about the consistence of sweet oil with spirits of turpentine, of which it
generally takes about 6 gallons. It is then left to settle for a day or two,
when it is carefully poured off from the grounds, and about 1½ pounds of ivory
or lamp black, and 1½ pounds of Prussian blue, ground in linseed oil, added to
and intimately mixed with it. It is then ready to be used as follows:-On
any description of leather, cloth, or other articles, having stirred up the liquid,
lay it on with a brush until it bears out with an even gloss; then hang up. the
subject acted upon until the next day, when repeat the application as before,
taking care to leave the surface thin and even as possible, and so on each
successive day until it has the desired appearance.
