    Peter can you tell me why the mixture boils by itself? Only Peter tells me!

      ​+Peter BrownHey! A question I can answer! (A couple of months later, but still.)
      I work with polyurethanes daily, in a different scale and application, but the chemistry is still largely the same.
      CAUTION: Some of the "steam" can be vaporized isocyanate, and it's not the healthiest thing to inhale. (Though most chronic injuries are occupational.)
      BUT some people can be/become sensitivized to isocyanate, when inhaling it in larger amounts than what it can vaporize in the short period of being unenclosed at room temperature. The super fast reaction here will do just that in a hurry.
      (Our suppliers earlier account rep became sensitivized and she had to change careers just due to that.)
      Still only injured-in-a-car-crash levels of risk, but a risk neverthiless.

      It's not *only* boiling, the water reacts with the hardening agent and releases carbon dioxide (which is the initial bubbling).
      The heat comes from the polyurea chains forming, and as it accelerates the reaction, the mix reaches unintentionally high temperatures and its fibre-time quicker.
      Fibre-time is the point when the foam forms/the resin sets, the foam insulates the inside (which can reach multiple times the temperature of the outside) and any residual water and hardening agent will turn to vapor, forcing their way out of the foam -> boiling effects.
      Also you're creating an extremely rigid foam with ridiculously large cells. :D

      Additional chemistry:
      2-component urethanes are primarily a mix of isocyanate 'hardener', and a polyol 'reactant'. The isocyanate is pretty universal/standard, but the polyol is where the magic happens. Solid (casting) polyols don't have any blowing agents mixed in (I work with foams, not solids and this is the major difference between the two).
      If you add water - that is used as a blowing agent in some foams - the water reacts with the isocyanate before the polyol group can get to it, which leads to:

      water + isocyanate = an urea group + CO2

      And you get nice cells/bubbles in your polyurethane with insulating CO2 gas inside them.

      Thanks for the explanation. Figured it was a chemical reaction.
      I've had this type of thing happen with epoxy resin except I mixed a huge batch on a very hot day and the 2 parts of resin was very warm.
      Mixed the 2 parts together, next thing I knew, the resin got extremely hot and started melting the cup. Dropped the dang cup before my gloves melted. Scared the ever loving life outta me. Now I just mix enough to do a layer at a time.

    A shallow wooden bowl with a rubber lip around the rim would have held the bottom of the bowl while you hollowed it.

    Sorry if someone already asked this. I read through as many of the >2,700 comments as I could! LOL I don't understand why you waited to pour the resin into the mold. Why not just mix the three ingredients and pour it right in? Great channel, Peter! :D

  • Kiera Kitten

    what if you did it with red and oranges and mixed them right after the other so they kinda mixed a bit, then added a layer of clear so... so fire lava bowl?

  • Richard Claymore
    Richard Claymore 16 days ago

    Peter: love your channel! Try putting a wood block on the bottom before you pour the first resin, then you can drill it out at the end. You can also take the lava bowl and dip it in resin to fill all the holes, which will give you a solid surface to hold onto with the chuck. Keep up the great work!

  • Jarrod Quinn
    Jarrod Quinn 20 days ago

    What if, once it was completely set, you used it as an insert for a clear resin bowl, and put clear resin inside (probably with its own insert, too.) Then you could lathe away the inside and outside (perhaps back down to the color) and have a smooth surface while the boiling, hollow effect is still visible

    Very pretty and interesting. But it looks fragile and likely to damage furniture. I wonder if you could put the lava bowl back in the mold, fill it with clear resin, vacuum chamber-ed it to get the resin into the voids in the resin and then pressure-pot it. It would be cool if the result was a lava-in-glass look with a traditionally smooth acrylic bowl. Just thinking'. Thanks for the experimenting.
