How to tell if a vegetable steamer contains titanium
If you mean metallic titanium - very unlikely. If you mean titanium compounds like the oxides - it is very likely. Titanium oxides are used in nearly all modern paints. I expect a fused ceramic coating is equally likely to contain titanium compounds. The people that write the info on the products are liberal arts majors and would not know titanium if it bit them. Metallic titanium would be easy enough to identify ; First is it magnetic ? If " yes" - not Ti. Does it feel "cold" ( assuming it is around 75 F), if "yes" - not Ti ( aluminum feels cold because of high conductivity) . Does it feel "heavy/dense ? If "yes" - not Ti ( stainless is about 50 % more dense than Ti). As these are relatively subjective tests ,it would be good to practice on known aluminum and stainless equipment first.  If necessary, grinding wheel spark test; aluminum - no spark . stainless - limited orange/red sparks, Ti -bright white sparks.
