Tycho Brahe dabbled in alchemy. Broken glassware is revealing his recipes
The shards contain nine metals that the famous astronomer may have used, including one not formally identified until 180 years after his death.

Artifacts from the ruins of a medieval laboratory are spilling a accurately-general scientist’s secrets and equipment.
A chemical evaluate of broken glassware belonging to sixteenth century Danish astronomer Tycho Brahe revealed elevated phases of 9 metals, researchers doc July 25 in Heritage Science. The discovering affords tantalizing clues to his work in alchemy, a precursor to dependent chemistry.
The astronomer is perchance best general for making the first observations of supernovas and being many of the first scientists to advocate that Earth orbits the sun (SN: 12/18/ninety 9). Even in addition to the truth that he also dabbled in alchemy. As an alternative than hunting to make gold from less powerful add-ons, he developed elixirs similar to the medicamenta tria — a trio of drug treatments that contained herbs and metals.
Brahe saved his recipes secret, even anything the reality, says chemist Kaare Lund Rasmussen of the School of Southern Denmark in Odense. What’s general about the medicamenta tria relies on secondhand bills.
Rasmussen analyzed the chemical composition of the perimeters of 1 ceramic fragment and 4 glass shards excavated from Brahe’s lab on the Swedish island of Ven. The chemist detected high phases of mercury, copper, antimony and gold — 4 metals general to had been used inner the medicamenta tria.
No one fragment contained all 4 add-ons. Heaps of these metals had been found on just the skin or inside facets, whereas others covered every facets. The vessels should have picked up the skin metals from unintentional splashes, or they are going to had been placed inner a greater vessel containing these add-ons, say Rasmussen and coauthor Poul Grinder-Hansen, a historian on the United states wide Museum of Denmark in Copenhagen.
Definitely the right 5 metals — nickel, zinc, tin, lead and tungsten — aren’t listed in any of Brahe’s preserved recipes. Accordingly of the the reality that all 5 of them had been found on the ceramic shard, alongside with copper and mercury, he may most likely have used the ceramic vessel to compile waste, the researchers advocate. Tin, lead, nickel and zinc had been ordinarily used inner the Renaissance world, Rasmussen says. “The most unfamiliar one grew to grow to be tungsten.”
Tungsten grew to grow to be first purposefully isolated in 1783, in truth a lot 200 years after Brahe’s loss of life. The metal’s presence on the shard should even be coincidental, Rasmussen says. Brahe may most likely have separated tungsten from every completely various cloth without realizing it.
Even in addition to the truth that there is a tiny hazard that the isolation grew to grow to be intentional. In the first 0.5 of the sixteenth century, German mineralogist Georgius Agricola stated that the presence of a particular substance (later referred to as tungsten) made smelting tin ore challenging. Perchance Brahe grew to grow to be investigating, Rasmussen speculates.
The discover out about is “definitely attention-grabbing,” says Laure Dussubieux, a chemist on the Container Museum of Herbal Facts in Chicago. Study on ceramic vessels is critical precipitated by making use of the factual truth they had been ordinarily used as cookware, she says. “A lot less work has been done to acknowledge what adaptation of inorganic matters may had been ‘cooking.’”
