If they can figure out Element-31, Element-49, and Element-50, mixing those in proportions of 68.5% Element-31, 21.5% Element-49, and 10% Element-50 will create a famous weird alloy that melts at slightly under the melting point of water and... probably goes higher than mercury before it vaporizes?  And is relatively not toxic, though you still wouldn't want to, like, drink a glass of that?  That's what Civilization uses when it wants metal that's liquid at room temperature.  If anybody knows about a light metal with a very low melting point, that's possibly Element-31.

...like, probably not, but Keltham thought it was worth mentioning.

The problem with identifying element-23 isn't going to be finding candidates, it's going to be figuring out which candidate is right.  Keltham can't really think of any easy Element-23 tests.  He doesn't have the melting point memorized, or the density, and he's drawing a blank on any other famous chemical reactions that involve vanadium.  It should be relatively light but it's not the lightest metal.  He's not even sure offhand if it's acid-resistant, the stage of the process where it's used doesn't involve a completed acid.

If Keltham can Prestidigitate calcium or some other nearby metal into behaving like vanadium by directly manipulating the similarity of its outer electromagnetic shell, and build a spectroscope, they could maybe burn the fake vanadium to see how it looks under a spectroscope, and burn real relatively-light metals under a spectroscope, and figure out which real metal looks like fake vanadium.  Possibly.

Have they got something that breaks up light into component frequencies, or 'colors' as they'd have it here, along a linear spectrum that runs from red to blue within its visible part?
