This thread reminded me that in the recent Fahrenheit scale thread my
homework was not quite good enogh, in that I could not assign a recipe
to his lower standard,known to be a mix of salt and snow or ice chips.

Here is what I have for a freezing mixture good for -18degC (0 degF):
2 parts by mass of snow or crushed ice
1 part by mass of common salt NaCl
