I am looking for non-destructible way which can be performed in home conditions to tell if the material is titanium (in my case it is a mug). Advices like "grind it" or "use electronic microscope" could be useful but I cannot apply them as stated above. I am targeting primarily aluminium and steel alloy because of their competitive prices and availability. In pure form detection would be easy (weight) but what about the alloy?
I am also asking for non-expert level ways -- I can weight something, boil water, measure temperature or resistance, those kinds of stuff. I am not a chemist for sure.
