Paper-mache? It doesn't generate any heat and should work...
You could try alginate moulding material. Everything else I can think of generates a lot of heat as it cures.

I'm thinking more of something I can spray onto the snow or ice, which will set fast, leaving a fine film which will support itself even if the snow or ice melts at that point. I can then spray more coats on until the mould can be touched.
I'd like to be able to make a mould from delicate stuff like ice crystals, icicles etc, and then eventually end up with a mould from which I can cast reproductions in metal, possibly through the lost wax process.
I might well have to go through a number of stages from the initial coating of the snow or ice, to get to a robust mould.
I wonder if snow can be sprayed with a polyurethane varnish.
I very much doubt it....... I guess it will immediately melt.
