To check out and testing whether your Titanium spoon, fork and knife are really made of Titanium or not is very easy and simple.
Just take a Titanium spoon and either a porcelain plate or bowl. Try to hold the spoon to rub against the interior wall of the plate or bowl. The wall of the porcelain plate or bowl will react immediately by changing colour.
The bowl as shown below had been used as a rice bowl having contact with the Titanium spoon for a few days and then you could see how the magic powers of Titanium is working.
