Arsenic, sulfur, when the wateriness of sulfurous bodies is mixed with viscous earth, through a strong mixture with the heat of boiling, until they have become virtuous, and before that they were coagulated by cold. But inks a term for mineral pigments or vitriols are composed of salt, sulfur, and stones, and it is believed that in them resides the mineral power of certain liquefiable bodies which are made from them, such as calcantum blue vitriol/copper sulfate, and olocar likely an alchemical name for a specific mineral, possibly related to ochre or a variant of iron vitriol, which are generated from larger grains of ink, and they are not dissolved unless the saltiness that is in the sulfur itself is dissolved with them, and they are previously frozen in the cold. And that now takes mineral power from certain bodies naturally existing in the earth. That which takes iron power will be red and earthy, like olocar. But that which takes airy power will be green calcantum. Hence, it is possible for these two, namely olocar and calcantum, to be generated from it, although all these aforementioned things participate in mineral power with metals. But metallic bodies cannot be made from them artificially, since they are of another nature, and they did not derive their origin from metals from the proximate first matter, namely Mercury, but from quicksilver. I do not deny that metals can be purged or dissolved with them, or a sophistic form introduced through them, to deceive men, because of which the blackness of lead can be wiped away, but lead always remains lead. Thus, art-
