the wood ; since you are to pass it over four or five 

 times, as above ; and if it be not yet smooth enough, 

 presle it again with the reeds, but now very tenderly : 

 Then rub it sufficiently with tripoly, and a little oyl- 

 olive, or water : Lastly, cover it once or twice again 

 with your vernish, and two days after, polish it as 

 before with tripoly, and a piece of hatters felt. 



THE COLOURS. 



To make it of a fair red, take Spanish vermilion, 

 with a quarter part of Venice lack. 



For black, ivory calcin'd (as chymists speak) 'twixt 

 two well luted crucibles, which being ground in 

 water, with the best and greenest copperas, and so 

 let dry, reserve. 



For blue, take ultra-marine, and only twice as 

 much vernish as of colour. The rest are to be applied 

 like the red, except it be the green, which is hard to 

 make fair and vivid, and therefore seldom used. 



Note, the right japon is done with three or four 

 layers of vernish with the colours ; then two of pure 

 vernish uncolour'd (which is made by the former 

 process, without the sandrac which is only mingled 

 and used for reds) which must be done with a swift 

 and even stroke, that it may not dry before the 

 aventurin be sifted on it ; and then you are to cover 

 it with so many layers of pure vernish, as will render 

 it like polish'd glass. Last of all furbish it with 

 tripoly, oyl, and the felt, as before directed. Note, 



By ^oenturine is meant the most delicate and slender 

 golden-wyre, such as embroiderers use, reduc'd to a 

 kind of powder, as small as you can file or clip it : 

 This strewed upon the first layer of pure vernish,
