En-am′eled Leath′er.
A glazed leather for boots, shoes, carriage upholstery, and other purposes.
It is prepared from hides, which are split to the required thickness, well tanned, curried, and passed through two operations; the first to render the leather impermeable to the varnish, and the latter to lay on the varnish.
The hides used are those of kip, calf, ox, or horse.
They are rubbed on the grain or flesh side with three coatings of boiled
linseed oil mixed with ochre or ground chalk, and dried after each coating.
The surface is then pumiced, treated with the same material of a thinner quality in several applications.
Over the surface thus prepared are laid successive layers of boiled
linseed oil and of the oil mixed with lamp-black and turpentine spread on with a brush.
The surface, which has become black and shining, is then varnished with copal and
linseed oil with coloring matters.
The following is recommended.
| Boiled linseed oil | 20 pounds. |
| Turpentine | 20 pounds. |
| Thick copal varnish | 10 pounds. |
| Asphaltum, or | 1 pound. |
| Prussian blue, or | 1 pound. |
| Ivory black | 1 pound. |
