SECTION III.
Of painting japan work.
JAPAN work ought properly to be paint-ed with colours in varnifh j the methods of which, I have before given, under the article of painting in varnilh, inp. 176, and the
following; though, in order for the greater difpatch, and, in fome very nice works in fmall,or the freer ufe of die pencil, the colours are fometimes tempered in oil: which Ihould
previoully have a fourth part of its weight of gum animi diflolved in it; or, in default of that, of the gums fanderac or maftic, as J have likewife before intimated. When the oil is thus ufed, it fhould be well diluted with fpirit of turpentine, that the colours may be laid more evenly and thin: by which means, fewer of the polifhing or upper coats of varnhh become neceflary.
In fome indances, water colours, as I be* fore mentioned, are laid on grounds of gold, in the manner of other paintings; and are bed, when fo ufed, in their proper appearance without any vamifh over them; and they are alio fometimes fo managed as to have the efled of embofied work. The colours employed in this way, for painting, are (as I before intimated) bed prepared by means of ifinglafs fize corrected with hony, or fugar candy. The body of which die embofled work is raife ° need not, however, be tinged with the exterior colour; but may be heft formed of very drong gum water, thickened to a proper confidence by bole armoniac and whiting in equal parts: which being laid on in the proper figure, ahd repaired when dry, may be then painted with the proper colours tempered in the ifin- glafs fize, or in the general manner with uiell-lac varnifh.
