Wasium was the suggested name of a chemical element found by J. F.
In 1862 Bahr analysed the mineral Orthite—Allanite-(Y)—from the Norwegian island Rönsholm and found an oxide which he concluded contained a new element.
In the following years several articles were published making clear that the wasium oxide was a mixture of several other elements.
[6] Wasium was supposedly found in the mineral wasite, which is a form of allanite.
