Freezing time for 1 cm of water

  1. Jan 19, 2014 #1
    Hey guys,

    I have a question.... first some backround. I am asking this question is so I can build a backyard skating rink in the fastest way possible. I live in south Jersey so winter is allot of freeze/thaw.

    The common way for a backyard rink is 1) place a liner 2) fill 2-3 inches 3) let freeze.
    This way, however, is tough in my climate because I would need many days of sub freezing temps to get a good slab of ice.

    So....I want to build it up 1 mm or cm at a time, while the temp is right, instantly adding the next layer as soon as the previous one freezes thereby saving time.

    1) is there a set formula to figure how fast 1 cm will freeze?
    2) does surface area matter ? (Im sure it does)
    3) how does the time to freeze change as temp drops lower

    Thanks in advance for any help.

    There are way too many unknowns to solve the problem as given.

    How are you going to make sure your ice doesn't melt when the temps go high?

    I wasn't too concerned about the melting. I am just interested right now how long a cm would take.
