Ice sticking to the mould problem.

  1. Jan 31, 2008 #1
    Hi, having a problem with the ice sticking to the mould. I have to use alginate for the mould and when the water freezes, so does the alginate.The moulds are part of my art project and they take amazing detail. I don't know whether I'm making sense here but is it possible to use something in between them?

    Alginate is capable of absorbing water and probably does so until the water freezes. You might want to try coating the inside of the mold with a light coating of PAM or some other cooking spray to see if that will block the absorption of water, so the mold will release after freezing.

    Cool thanks a million for your time, I will try that one tonight.

    Still having problems

    Well I tried cooking oil, couldn't get a spray and the oil just rose to the top of the water. Is there anything else that might work. I was even thinking is there anything other than water that would create a clear mould?

    Would Teflon or "Scotch-Gard" work?

    Try WD-40. I'm not sure that it will work, but it is, after all, a Water Displacement formulation.

    How about silicon spray lubricant?
