“This white substance, if you will make it red, you must continually decoct it in a dry fire till it be rubified, or become red as blood, which is nothing but water, fire, and true tincture. And so by a continual dry fire, the whiteness is changed, removed, perfected, made citrine, and still digested till it become to a true red and fixed color. And consequently by how much more it is heightened in color, and made a true tincture of perfect redness. Wherefore with a dry fire, and a dry calcination, without any moisture, you must decoct this compositum, till it be invested with a most perfect red color, and then it will be the true and perfect elixir.” - Artephius.
