I've just been reading about Arthur Machen. It's thought that this charming article about alchemy in Household Words first inspired his interest in esoterica at the tender age of 8:

The Alchemy of Glass Counterfeit, Imitation, and Transmutation in Ancient Glassmaking

Marco Beretta
Published 2009
The book illustrates how glass played an important role in ancient technical and alchemical literature and how the chemical operations devised to improve glass-making inspired alchemists to better define the theoretical boundaries of their discipline and, more specifically, the notion of transmutation.

"Any student of history can tell you there is a myriad of professions that no longer exist due to technological advancement, societal trends, or some combination of the two. One such profession is alchemist, which was a term for the earliest students of chemistry, though they didn’t know it at the time. Potion Craft: Alchemist Simulator developed by niceplay games and published by tinyBuild gives a peek into what that lifestyle could have been like in ye olden times."

I recently found this rather puzzling alchemical emblem. I can't recall seeing anything quite like it
It is a folded parchment sheet in

University of Kassel, 2° Ms. chem. 24

It is entitled, Spherae sive Compassi mineralis Nova inventio  (A New Discovery of the Mineral Sphere or Compass)

It was created by Justus de Buschia, probably in 1552.


Six rays stream down from heaven and are being collected in a hemispherical vessel. It has a number of holes in its base, and beneath this, on the platform supporting the hemisphere, there are six circular discs. The rays from above shine through the holes onto these discs, which are labelled, Iovis, Solis, Lunae, Martis, Saturni, and Veneris. These discs each bear a symbol that I cannot quite make out.

Here is an interesting diagram found in Athanasius Kircher's book on alchemy in his Mundus Subterraneus.

The Latin text appears to say.
Whatever is contained in the whole of alchemy is set before the eyes of the inquisitive reader, as if in an anacephalaeotic synopsis. And outside of this, whether you look at the manufacture of stone, or at the metallurgical art, or at the mixtures of metals, or again at their genesis, do not look for anything useful and fruitful for chemical operations.

In this combinatorial chart, the imperfect metals and substances all seem to trace themselves back to the perfect metals plus sulphur.

   

Newton wrote and transcribed about a million words on the subject of alchemy. Newton's alchemical manuscripts include a rich and diverse set of document types, including laboratory notebooks, indices of alchemical substances, and Newton's transcriptions from other sources.
