Idk how common it is, yet I grew up where I was taught to know which material something is (if I couldn’t tell visually or physically) by tapping it on my teeth from wood, metal, glass, stone, bone, etc. I’m not always right yet for example if I’m holding something that is light and painted, I can tap it on my teeth and tell if it’s wood or plastic. If it’s a faux material I can usually tell by teeth tapping.
