Color your applied silver leaf with terre emerita, and once dry, give a coat of spike lavender oil varnish and of sandarac. And it will be more beautiful than tinsel.
Layer of burnished gold on paper
Make your ground layer of starch soaked in water & your gold will burnish very well. Clear starch water layered on the paper, then dried, & repeated in this manner 3 times, is a good layer for burnished gold on simple paper & has no body.
Removing stains
A good eau de vie takes it off if you rub your cloth with it.
Ground layer of gold
Ground terra emerita with some saffron, all of it mixed with very clear colle forte & passed through a linen cloth.
Extraction of oils

Dragon’s blood
Take a well chosen tear of it which shows off its transparent red. And in a glass bottle put the best eau de vie you can find, in sufficient quantity. For it And stopper it well and so quickly that it does not evanesce, otherwise it would be worth nothing. And leave it thus for a long time, because the longer it stays there, the more beautiful & better it will be & it will dissolve if it is good, otherwise it will become like lees. When you want to use it, make a small hole in the stopper of the bottle & pour a little & stopper it again each time, then apply it on gold.
The good kind of dragon’s blood can be found in large pieces like torteauthis one has no value and is adulterated & once broken it shows on its edges scales, transparent as ro rouge clair enamel, it is also lumpy in some parts like small rubies. The eau de vie nees to be very afrdent & passed several times.

I put it in common eau de vie, mixing in some aqua fortis to give it strength. At the beginning the water took on a slight tint, but at the end there was only an appearance of tragacanth gum with which I think they adulterate the dragon’s blood.

When it is applied on burnished gold, it is prone to break. For this reason, some coat it with turpentine varnish. Cold delays the action of the water and the extraction of the color. And for this reason, you can keep it by the fire.
