Congratulations, you created a medieval pigment called verdigris! Take your crystals, grind them and mix them with oil or egg tempra and you'll be painting like Michaelangelo in no time!
But seriously, everyone is right, that stuff is toxic, and you should look into the proper cleaners for your copper sink.

So, those crystals are quite poisonous.
As well, judging by the size and number of them, you dissolved a decent amount of metal from the sink when you did it.
In other words, don't use salt and vinegar to clean your sink.
