Make Bio-Plastic From Milk

  • Published on Jun 18, 2016
  • Making bio-plastic from milk! In this video I will attempt to make casein into blank hard enough to turn on the lathe and shape into a tool handle!
    That's right, I'm going to be turning milk at 3000 RPM's!
    The process wasn't easy for me, but the end result is a satisfying tool with a handle made from milk!

    I wish I saw this when I first started my project, instead of basing it on this. Was sold on the idea of it taking 2 days and I have a major deadline soon, fuck...

    if you want it super hard try heating the casein in Benzaldehyde ( like synthetic Almond Extract . It will form crosslinks and get much tougher .

    I feel like you could get similar results by letting a block of mozzarella dry, plus, then you could just cut blanks instead of having to mold them.

    You and the other video were trying to make casein, but you're product didn't turn out right, since you didn't purify it enough. You noticed yourself that the product was oily. That's because you didn't get rid of the oil. There are other channels that show you how to purify this stuff and get a decent plastic.

    If you had added salt, you would have made cow's milk ricotta.

    This video shows several different methods of making the casein. Long but interesting. The end result is a very sharp kitchen knife :)
    He did some extra steps like washing it and heating it in a pan before leaving it to harden.

    You may need to compress the curd you use. Idk how, tho.

    You can’t use whole milk, it has too much fat in it. Here is a great video by an actual scientist. He’s not as entertaining as you are but he is thorough and knowledgeable. Hope this helps.
    By the way he shows how to make molds for silicone, that is thin enough to pour.

    When it broke off the lathe I didn't know whether to laugh or cry... I'm so sorry, but the laugh won and rang out loud and clear. But you persevered, and won thro. You're a crazy, crazy guy. lol; but so witty and tenacious.

    Non-fat would work much better. You are denaturating the milk proteins by doing so, and fat does not help at all.

  • Suzette Kath
    Suzette Kath 2 months ago

    Casein plastics aka milk plastics were introduced at the beginning of the 20th century, their starting material being the protein in cows milk, precipitated by the action of the enzyme rennin.
    Although casein is readily moulded to shape under moderate heat and pressure, it does not produce a stable material for manufacture until it has become hardened by soaking in formalin (5% solution of formaldehyde in water) for a long period. Unfortunately, this causes much distortion so casein plastics are almost always produced by machining stock material such as sheet, rod, tube or buttton blanks (small discs). After machining, casein may be polished either mechanically with abrasives or chemically with a ‘dip polish’.

    Hey Pete! Just watching old videos of yours, and after watching this one and seeing your determination - I'm not sure you'll see this but I'm into knife forging as well. Kiwami Japan creates knives by hand with no power tools out of very random mediums. He created a very successful milk knife that actually cut, and worked wonderfully. If you decide to give milk another chance, I suggest watching his video to observe his methods and perhaps try them on your own. Here's the link: - and keep it up man! You're entertaining and passionate and have such a beautiful, supportive family. Thanks for all the content!

    This is pretty interesting. I remember doing this experiment in Girl Scouts, of all things. I also remember the results being disappointing. I wonder if rinsing the curds and then kneading them (like people do with mozzarella) would result in a stronger plastic? I can also see how the fats in whole milk would make it more crumbly.

    i would dye it and degas it and then push it into a cylinder and force it through so it comes out like a cylindrical blank and then have something you could turn. make some pen bodies or handles.

    The problem with the drying might be because he left it in the mold. If you allow all sides to dry evenly it works better. Also, thicker blocks have difficulty drying in the middle.
    It is a non-polymer plastic using the long chain proteins in Casein (milk stuff)
