I have tried two different mosaic methods (i) the standard "amateur" direct method given in textbooks of siliconing vitreous glass tiles onto an existing slab and then beating in mortar grout; and (ii) using the reverse method, beating in a thin grout layer and then casting a slab on top. We had a week in January with temperatures around -12C at night and -5C daytime, some of the method (i) tiles popped out; the method (ii) tiles were perfect.
