How come when you heat milk it gets a thin layer over the top of it?

Question

what is the layer and why does it happen when heating/warming milk up?

Answer 1

Its just where the heat has made a skin of milk. its just what happens lol

Answer 2

Its the skin, and your heating it to long.

Answer 3

i feel the same way .....................WHY!!!!!!!!! I don't like when that happens so i throw the milk out

Answer 4

It's the protein separating from evaporating water.. (it's water and not milk because 'milk' is a suspension of different substances which include water and protein)

Woah... look at that! I did listen in science after all!
