S52 JAPANNING. 



Yellow Japan Grounds. 



For bright yellow grounds, king's yellow, or 

 turpeth mineral should be employed, either alone 

 or mixed with fine Dutch pink, and the effect may 

 be still more heightened, by dissolving powdered 

 turmeric root in the spirits of wine, of which the 

 upper or polishing coat is made; which spirits of 

 wine must be strained from off the dregs, before the 

 seed-lac be added to it, to form the varnish. 



The seed-lac varnish is not equally injurious 

 here, and with greens, as is the case of other co- 

 lours; because, being only tinged with a reddish 

 yellow, it is little more than an addition to the force 

 of the colours. 



Yellow grounds may be likewise formed of Dutch 

 pink only, which, when good, will not be wanting 

 in brightness, though extremely cheap. 



Green Japan Grounds. 



Green grounds may be produced by mixing 

 king's yellow and bright Prussian blue, or rather 

 turpeth-mineral and Prussian blue. And a cheap, 

 but fouler kind by verdigris, with a little of the 

 above mentioned yellows, or Dutch pink. But 

 where a very bright green is wanted, the crystals 

 of verdigris, called distilled verdigris, should be 

 employed; and to heighten the effect, they should 

 be laid on a ground of leaf gold, which renders the 

 colour extremely brilliant and pleasing. 



Orange Japan Grounds, 



Orange coloured japan grounds may be formed 

 by mixing vermilion, or red lead, with king's yel-
