    Hi, may I ask how you achieved that kind of consistency for your cornstarch bioplastic? I'm also researching cornstarch-based bioplastics, and I tried doing the same, but the results weren't great. Since I'm limited with the materials such as a molder, I tried using wax paper instead to place my mixture. However, cracks keep appearing☹

    • @giestas
      @giestas  2 года назад +17

      Cracks are usually caused by insufficient glycerin and/or water. If it still cracks, maybe try duct taping the waxed paper to a piece of cardboard so it doesn't shift during the drying period.

    • @giestas
      @giestas  3 года назад +2

      A glycerol substitute you might have at home is honey. Depending on the viscosity of your honey, you might have to increase the amount (try doubling it, for example).
      Regarding the gelatin, I've never tried that; if you do, let us know if it works!

    Hi i would like to know what u mean by parts is it spoon or cups thank u

    • @giestas
      @giestas  Год назад +1

      When you see a recipe expressed in 'parts' that means you are looking at the recipe 'ratio', which is supposed to help you scale the quantity up and down.
      Example: let's say you don't have measuring spoons at home and all you have is a small coffee cup. If the ratio called for 3:1:1:1, that would be 3 cups of water, 1 cup of starch, 1 cup of vinegar, 1 cup of glycerin.
      Then, let's say you wanted a bioplastic that was double the size. You can use a coffee cup that is double the size, or, following the same ratio 3:1:1:1 all you need to do is double the numbers, so that would be: 6 cups of water, 2 cups of starch, 2 cups of vinegar, 2 cup of glycerin.

      It might take a long while for all the water to evaporate from the bioplastic, so if it hasn't "hardened" after 8 days, wait a bit longer and check if it's gradually drying.

    • @giestas
      @giestas  2 года назад

      With a dehydrator on high temperature (70ºC) you can dry it fast but it introduces a lot of small bubbles into the bioplastic. On low temperature (35ºC) it's quicker than air drying, but it might still take you something like three days.
