I've been liking the idea of using silicone molds, sorry about the youtube shorts link but - https://www.youtube.com/shorts/lEmRFM_9RK4
That’s really fun, I’m going to have to give that a try
This is awesome, thank you! Now I need to learn silicone mold making 🤔
This! Grind it down to granules with a cheap food processor and use it in molds with a heat gun
A heat gun!
That's the piece I've been missing. I've been using a spare toaster oven, but can never get the amount of plastic right for the mold lid to sit right. Finishing with a heat gun would probably make this easier to solve
Yup! And you can melt the plastic in layers so you get a nice solid core, or fill the very center with rocks or weights or what have you to reduce how much plastic is in it.
I would recommend getting some heat prof material to set the mold on, in, and some heat proof gloves as well in case you need to use a small metal bar to move the melting plastic around
Bonus points for separating your plastic into colors, lets you do some cool swirly affects and what not vs. just a mishmash of colored specks
