The Chemical Writings of Brother Basilius Valentinus: The Treatises of Heinrich Eschenreuter

...out, and place it into a retort a glass vessel with a long, downward-pointing neck used for distillation and drive it over in sand using a sand bath for even heating, and so you will obtain a penetrating Antimony original symbol: a circle divided into four by a cross. Pour this back onto the remaining matter and draw it off again; do this as often as necessary until, through cohobation the process of repeatedly redistilling a liquid from its own solid residue to concentrate its essence, you see a noble oil, like a sapphire stone meaning a brilliant, transparent blue, pass over. From the residue original symbol: a circle with a cross and a small diagonal stroke on the top right, representing the remains of the distillation you can extract a beautiful salt original symbol: a circle with a horizontal diameter by means of clear rain-water. When this has been extracted, boil the water down again, so that the salt remains in the pan in which it was boiled, appearing entirely gray. Place this into a melting-pot and let it glow thoroughly calcination through high heat, and it will become like a stone. Of this same salt take one Loth a historical German unit of weight, approximately 15-16 grams or half an ounce, and of the Antimony take half a Loth, and of the oil of Antimony and Mercury/Spirit original symbol: a circle with a cross below and a crescent with a horizontal bar above also take one Loth. Place these into a cucurbit a gourd-shaped glass vessel and let it digest gentle, continuous heating for one philosophical month original symbol: a circle with a diagonal slash. Then this substance will turn into a blood-red color; when you see this, you can maintain the fire original symbol: an upward-pointing triangle for another month, and it will become quite dark and greenish. After the end of the indicated time original symbol: a circle with a cross-like mark and a vertical line, it will begin to become blue-colored,
