Identify Magic Item

A magic item’s properties can be learned in two ways:

Sometimes a magic item carries a clue to its properties. The command word to activate a ring might be etched inside the band, or a feathered design might hint that it’s a Ring of Feather Falling.

Wearing or experimenting with an item can also offer hints about its properties. In the specific case of Potions, a little taste is enough to tell the taster what a potion does. Other items might require more experimentation.
