124v - - - - - Rouge clair @ enamel
Fine gold is opposed to it, for on this it remains yellowish. But alloyed gold is more appropriate to it, such as that of escu & pistolet. If Gold f is not put back on the fire with its own pale color turns the enamel a dead colour. Ma> And for this occasion, once cut, one puts it back on the fire to give it a reddish color to make the enamels beautiful. Otherwise, they are subdued.
There is rouge clair which, once it is worn down with arene, loses its beauty.
There is some which has grains of gold inside. And it is also the opinion of good goldsmiths that the good one is made with gold.
Casting with gold
Molds are recooked better & more surely than otherwise in a closed fire, such as a pot a reverberatory furnace. So that when goldsmiths want to cast some piece of important work d’or e that cost a lot to rough out in wax, they put the molds in a pot & recover them, & fill the pot with earth, sustaining the fire that holds them unified & tight. Then, they recook mold, earth & pot together and when everything is quite red, they cast the gold. Fine gold does not run well, but rather alloyed gold.
Gold and silver do not become brittle: once entirely red and hot, dip them into water.

A way to make the gate for small female lizards
Because you always have to make the gate by the tail, and that it is so delicate and thin that the casting scarcely metal would flow with difficulty, especially when the tail is folded, roll wax in little filaments of this size

and apply some with the hot wire, as said, one at the end of the tail & others that correspond in the same way, from one end side of the tail to the other, as you see depicted. But take heed to do it with the end of the hot iron so that the end of the wax scarcely touches the animal, for the sand of the second gate will not touch this part. But make the end of the wax arranges itself only at the end of the empty part of the first mold. Make as well channels of wax around the legs &, around the contours of the body, which are a little long & they will serve as a trough for the molded thing. [continued]

When the tail, which is delicate and closer to the gate comes out well, the rest will also come out well.

The most important is that the ears of the snake come out well—molded.

Your gate must be very thin at the entrance of the animal & of the thickness of a knife.
