Fair point. I also just made a scratch test. As far as I shouldn't be able to scratch titan like that, for me it looks like it's some titan like color coating and regular aluminum inside. Am I missing something here?
Titanium tends to change color if it is heated to a high degree so it's not good to boil water. Get a stainless steel Bowl from Avias which I've been using for more than 3 years, its quality is good and there is no change in steel texture too. I don't know if it's available for other countries so I'll share a link below.
