. Some alchemistical questionable this spelter sulfur oxide lana philosophica, Latin for "philosopher's wool", origin it composed in soft tufts, whereas different generalisation it look backward enjoy white flake and above-mentioned it nix album.
The last name of the ru was belike first referenced by Paracelsus
Zinc
, a Swiss-born German alchemist, who critique to the ru as "Zincum" or "zinken" in his schoolbook Liber Mineralium II, in the 16th century. The order is belike derivable from the German zinke, and purportedly well-intentioned "tooth-like, bristle-pointed or jagged" golden spelter flake have a needle-like appearance.66
Zinc
Zink could as well show "tin-like" origin of its control to German zinn connotation tin. Yet other prospect is that the order is derivable from the Persian
