| Apr 24, 2014 at 6:21 | comment | added | dotancohen | This is a terrific question, evidenced by the fact that the canonical explanation "the crystalline structure of ice is six-fold" does not address why refrigerator ice is not hexagonal. | |

| Apr 23, 2014 at 7:36 | comment | added | Kenshin | @naught101, that answer is insufficient and I wouldn't accept it as best answer. It doesn't answer why the arms grow in a hexagonal shape.You could say "because the microstructure is hexagonal", but that doesn't answer the question very deeply does it? Why does the hexagonal microstructure lead to the arms grwoing in the same way? Maybe the superficial wikipedia article is enough for you, but certainly it is not enough for me. | |
| Apr 23, 2014 at 7:11 | comment | added | naught101 | I feel like this answers the edit to your question: "The micro-environment in which the snowflake grows changes dynamically as the snowflake falls through the cloud, and tiny changes in temperature and humidity affect the way in which water molecules attach to the snowflake. Since the micro-environment (and its changes) are very nearly identical around the snowflake, each arm can grow in nearly the same way." - Could you at least ask your question with reference to these statements? e.g. state what problems you have with them, and what specific parts you would like clarified? | |
| Apr 23, 2014 at 7:07 | comment | added | Kenshin | @naught101, it still doesn't describe why one particular hexagonal formation occurs over another type of hexagonal formation. See the last part of my modified quesiton. | |
| Apr 23, 2014 at 7:06 | comment | added | Kenshin | @naught101, I've read (a) but I'm still unsure of why ice in particular forms such structures. (b) It does not properly describe how the microstructure affects the macrostructure scientifically. Sure it gives some waffle about how it might be plasuable, but I certainly wouldn't accept it as a best answer if that answer was posted here. Experts should be able to do better. | |

| Apr 23, 2014 at 5:35 | comment | added | Kenshin | @naught101, that portion of the article is brief and not really clear. Can you please elaborate on (a) why the crystalline structure ice is "six-fold" and what that means, and (b) how the crystalline structure give arise to the shape of the above crystals and why each crystal as a unique shape? The wikipedia article isn't really clear on these issues, but if you can interpret that page and post as an answer I will accept. | |
