I have nochildren so who am I to give advice...
But I had development psychology at uni in the past
It's normal at that age to be inquisitive, feel things, and test limits
At 14 months I don't think sending to a room will help, too young for that
A lot of patience and keep taking things away that she shouldn't have, saying NO in a low voice, plus eyecontact and coming down to her level.

When she is older and understands consequences of bad behavior better, you can try a naughtymat or naughtycorner, where she has to stay for 2 minutes, (ignore any screams or tantrums) then you go to her and explain that this was not acceptable, down on her level and eyecontact, she has to apologise and then can go back to playing.
Do this consequent and it works, but she's too young for this now I think.
