    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 роки тому +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  Рік тому

      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.
