102v - - - - - Painting on crystal or glass
They paint in oil without lines, except for the faces where they trace the nose & the mouth with black in small work, then they make strokes & and highlights in white, next they coat all with carnation. And as for the ground, they make it with azur d’Acre for more beauty, or with lake for a quickly—done red, or with dragon’s blood for the most beauty. But one needs to layer it little by little so that it appears even & of one color, & thus for other colors. Next they put underneath it a leaf of topaz, or one of gold or silver.
Infusion of anthos or rosemary
It is better to cook the flower in August & more suited to oil—making. Take as much as you want. Then put it into a bottle very well corked, & leave them to wilt in the shade for a day. Then add the first substance of wine & leave to settle three or four days; & express it all in another vessel and into this very same substance of wine, add seven or eight infusions made out of new flowers. Then leave the latest infusion in the sun for a month. Then distill it through a still. Then mix two ounces of this water with two or three spoons of white wine; but this is for the elderly.

Tin comes out better being thin & fine, rather than thick, because being thick & in great heat, it retracts. Therefore, if you want to mold a thick piece in tin, mold it only on one side, & with a cavity on one side, if it is possible, in that way you will have it more neat, and then you will be able to solder two halves together. But if you have to mold it thick, make it in the form & mold a lot of abrevouers around the figure, in this way.
