Experiments with ice-shader techniques in Maya...following this tutorial link
and then further experimentation and adjustment of settings....
Test heads using the mia_material_x presets
Blinn material with the transparency turned downThe Raytrace settings at '4' give a fiery look, which could be a good effect when the ice men are about to melt
Using a ramp shader and a bump map with a noise node in hypershade...the bump map depth is set to 0.005 to give some texture...
Next step is to continue adding lights so that the features begin to stand out
