Ok. Whatever. A thin layer of ice is
always visible, regardless of lighting and where it is. And ice cannot be white either. Got it. Thanks.
Edit:
I missed this the first time around:
Black IceŽ can form at temperatures as high as 40°F (4°C). That violates a whole bunch of physical laws.
I haven't heard up to 4, but 2 degree C. But that process is called "nucleation" and doesn't involve violating any physical laws.
