How to french polish



The varnish being prepared (shellac), the article to be polished being finished off as smoothly as possible with glass-paper, and your rubber being prepared as directed below, proceed to the operation as follows: The varnish, in a narrow necked bottle, is to be applied to the middle of the flat face of the rubber, by laying the rubber on the mouth of the bottle and shaking up the varnish once, as by this means the rubber will imbibe the proper quantity to varnish a considerable extent of surface. The rubber is then to be enclosed in a soft linen cloth doubled, the rest of the cloth being gathered up at the back of the rubber to form a handle. Moisten the face of the linen with a little raw linseed-oil, applied with the finger to the middle of it. Placing your work opposite the light, pass your rubber quickly and lightly over its surface until the varnish becomes dry or nearly so; charge your rubber as before with varnish (omitting the oil), and repeat the rubbing until three coats are laid on, when a little oil may be applied to the rubber and two coats more given to it. Proceeding in this way until the varnish has acquired some thickness, wet the inside of the linen cloth, before applying the varnish, with alcohol, and rub quickly, lightly and uniformly the whole surface. Lastly, wet the linen cloth with a little oil and alcohol without varnish, and rub as before till dry.

_To make the Rubber._

Roll up a strip of thick woolen cloth which has been torn off so as to form a soft, elastic edge. It should form a coil from 1 to 3 inches in diameter, according to the size of the work.
