not come out as clear as I wanted. I reheated it again, let it cool, put it into the bleach again, and brushed it. It came out very clear. In this way, you will do the same for copper and silver. And if you want to give…
Beautiful color for brass
Having cleaned it well, as is stated, and brushed it well, boil it in water with curcuma root or terra merita, and it will become very beautiful.
Bleach
If it is for silver, do not grind your tartar with something made of iron, but with the handle of a hammer, because if you touch your tartar with iron and end up getting some iron in your bleach, the silver will come out red, like copper, and you will need to reheat it and put it back in the bleach. Mix in nothing with your tartar that should not enter the bleach, because this ruins it. Do not let it spill out when it first starts to boil because all its strength is in it at this point. Bleach is made with one part pulverized tartar and a half part of common salt.
Moulding the foot of the bittern, or eagle, or other birds for the base of saltcellars or vases
One commonly molds the foot and the legs up until the calf. And for this effect, one molds it in five pieces: the leg in two pieces, the top of the foot in two, and the bottom in one piece.

Crocum Ferri
To make this quickly, redden the filings in an iron ladle, stirring it often. Then sprinkle it with some good vinegar and let it evaporate. And without taking it away from above the fire, let it redden and take flame. Having been cooled, pulverise it on the marble and return it to the heat, sprinkle with vinegar, and then set it on fire. In this way it will soon be colored and made fine.
