JONES, ON JAPANNING AND VARNISHING. S3 



once ; as the rubber will thus imbibe just a suflicient quantity to 

 varnish a considerable extent of surface. The rubber must then 

 be enclosed in a soft linen cloth, doubled ; the remainder of the 

 cloth being gathered together at the back of the rubber, to form a 

 handle to hold it by ; and the face of the linen cloth must be 

 moistened with a little raw linseed oil, (which may either be color- 

 ed with alkanet-root. or not.) applied with the finger to the middle 

 of it. The work to be varnished, should be placed opposite to the 

 light, in order that the effect of the polishing may be better seen ; 

 and a surface of from one to eight feet square may be varnished at 

 once. 



" The rubber must be quickly and lightly rubbed on the surface 

 of the article to be varnished, and the rubljing continued until the 

 varnish becomes nearly dry ; the coil of woollen cloth must be 

 then again wetted with the varnish, but no more oil need be appli- 

 ed to the surface of the linen cloth, and the rubbing again continue 

 till the varnish becomes nearly dry, as before; and again, a third 

 coat jnust be applied in the same manner ; then one with a little 

 oil ; which must be followed, as before, with two others without 

 oil ; — and thus proceed until the varnish has acquired some thick- 

 ness, which will be after a few repetitions of the series ; when a 

 little alcohol may be applied to the inside of th3 linen cloth, before 

 wetting the coil with the varnish ; and then rub very quickly, light- 

 ly, and uniformly, over every part of the varnished surface, which 

 will tend to make it even, and very much conduce to its polish* 

 The linen cloth must next be wetted with a little alcohol and oil, 

 without varnish ; and the varnished surface being rubbed over, 

 with the precautions last mentioned, until it is nearly dry, the 

 etfect of the operation will be seen ; and, if it be foufid that it is 

 not complete, the process must be continued, with the introduction 

 of alcohol in its turn, as directed above, until the surface be- 

 comes uniformly smooth and beautifully polished. 



" On varnishing hollow and round works. 



" In this case, the woollen cloth is not to be used with its flat 

 end, but on its sides ; to which the varnish must be applied, as be- 

 fore directed, and be covered with two folds of the linen cloth, 

 oiled or not, as before mentioned. 



" On varnishing recesses or carved work. 

 " When this occurs in cabinet work, &c., and where the surfaces 

 are not liable to wear, or are diflicult to reach with the rubber, a 

 spirit varnish, made with, or without lac, of the usual gum resins, 

 and considerably thicker than that used in the above process, may 

 be applied to those parts with a brush, or hair pencil, as is com- 

 monly done in other modes of varnishing. 



" On varnishing works in the lathe. 

 " This process is exceedingly easy ; and does not require much 

 more skill than the mere application of a little oil to the surface of 

 a soft linen cloth, and putting the lac-spirit-varnish upon it ; then
