“The presence of W is most peculiar <\/strong>and unexpected. Tungsten in its pure form was not known to alchemists in Brahe\u00b4s times. It was discovered as a new element and isolated as a metal only by the end of eighteenth century. Important W ore minerals include scheelite (CaWO4<\/sub>) and wolframite ((Fe, Mo) WO4<\/sub>). Molybdenum was not measured in the present work, so a distinction between these two minerals cannot be made in the present project. It can be speculated that a W bearing mineral was included in a process conducted in the laboratory not knowing the nature of this mineral or by mistaken identification of the mineral. Still, the source of the elevated W levels remains a real puzzle.”<\/p>\n\n\n De unders\u00f6kta sk\u00e4rvorna.

A series of elements were found not to be enriched on the surfaces of the five shards: Na, Si, P, S, Cl, K, Mn, Fe, Rb, Sr, Rh, Pd, Ag, Cd, Ba, Re, Os, Ir, Pt, and Tl. These elements could have been undetected due to the low number of shards analysed in the present study, but it could also be so that minerals containing these elements were not present on the shelves of the Uraniborg laboratory. On the other hand, the present work documents the presence of excess amounts of nine elements: Ni, Cu, Zn, Sn, Sb, W, Au, Hg, and Pb, collectively on the inner and outer surfaces of the shards. Four of these elements, Cu, Sb, Au, and Hg, are known to have been used in the three reconstructed recipes of Brahe\u2019s Paracelsian medicine, and these preparations could thus have been made in the alchemical laboratory on Ven. It should, however, be stipulated that the presence of these elements is not a proof that they were indeed used for making Brahe\u2019s medicine. The other five elements Ni, Zn, Sn, W, and Pb, were not mentioned in the preserved recipes and are therefore likely residues from alchemical experiments of an unknown character. The results of the present work offer a first unique glimpse into the alchemical work of Tycho Brahe\u2019s laboratory on Ven.”<\/p>\n\n\n\n Kaare Lund Rasmussen<\/strong> vid Syddanska universitetet, en av forskarna bakom studien, spekulerar i om volfram fanns i n\u00e5got mineral som Brahe arbetade med utan att veta om det. Eller kanske visste han redan om \u00e4mnet men sade inget om det.Som flitigt ut\u00f6vande alkemist studerade Tycho olika medicinska \u00f6rtblandningar. Han ans\u00e5g att kemi och astronomi h\u00f6rde ihop och skulle unders\u00f6kas parallellt. Brahe var dessutom f\u00f6rtjust i den schweiziska l\u00e4karen och naturfilosofen Paracelsus, <\/strong>som menade att all materia var uppbyggd av svavel, kvicksilver och salt, och att m\u00e4nniskan styrdes av en himmelsk kraft. <\/p>\n\n\n Tycho Brahe, \u00e4ven alkemist med en och annan hemlighet..

Kvicksilver, koppar, antimon och guld anv\u00e4ndes ofta f\u00f6r att framst\u00e4lla l\u00e4kemedel under denna tid, vilket tyder p\u00e5 att Brahe anv\u00e4nde dessa i sina mediciner. \u00d6vriga \u00e4mnen indikerar att han inte bara framst\u00e4llde l\u00e4kemedel i sitt alkemilaboratorium.<\/p>\n\n\n\n En professor fr\u00e5n Johns Hopkins-universitetet i USA, som inte var involverad i forskningen, kallar fynden \u201d\u00f6verraskande\u201d och s\u00e4ger att det kommer att vara av intresse f\u00f6r historiker och arkeologer, rapporterar CNN<\/a>.<\/p>\n\n\n\n \u2013 Vi vet v\u00e4ldigt lite om hur mycket man experimenterade med volfram under den tidiga moderna eran, s\u00e4ger han till kanalen.<\/p>\n\n\n\n P\u00e5passligt, aprop\u00e5 ovanst\u00e5ende, sl\u00e5r Pettzy Ahlstr\u00f6m<\/strong> ett slag f\u00f6r Cassiopeia – kvarteret i Gamla stan, Stockholm.<\/p>\n\n\n Omr\u00e5det har kvartersnamn efter en m\u00e4ngd gudar och d\u00e4rmed stj\u00e4rnbilder.
