And just what law is that?
The fictional force between two objects is dependent upon two things, the normal force and the coefficient of friction.
The normal force depends upon the weight of the object (and the angle of an incline it might be on). The coefficient of friction depends upon the type of objects which are rubbing together (the coefficient of friction between ice and steel is much less than between sand paper and wood for example).

F=(mu)N; where (mu) is the coefficient of friction and N is the normal force. this (mu) varies from material to material. For example the value of this for ice on a metal surface is very small compared to that between rubber and the same surface. So if the weight of both objects is same and are at equal angles to the horizontal,so that N is same, then the case where this constant is greater will experience more friction.

What law? Of course it depends of its material, the friction between two cubes of ice is diferent than the one on two cubes of rubber

Wouldn't it depend on the molecular structure of the material? Atoms and electrons and that stuff...
I don't know about the law though... I have a very rough understanding of physics.

that is true, just more or less friction
