I will add cobalt, nickel, and titanium and vanadium to the list – that is, if I can get the thing to work and add a camera, so a long term project which can be dipped into. The data will build up.  I’ll have to check that I have some vanadium and titanium, but if not, I may have a steel with some in. But obviously better to have the pure stuff so I know all the lines come from one element. The amounts in steel are often such that the spectrum will be dominated by iron, and some lines will be difficult to see if they are not as intense.  Anyone got any pure vanadium and titanium? I’ll gratefully accept a small chunk, plate. Just has to be a surface area of at least 2 inches.
