Does anyone have a small round-bottomed bowl made of rubber, silicone, or other flexible material that you'd be willing to sell? The condition doesn't much matter because I'll be mixing small batches of molding plaster in it. After any residue hardens, the "rubber" bowl can easily be cleaned by flexing the sides.
"Small" for my current project means able to hold about one cup of liquid or slightly less, but if you also have other sizes I'd be interested in them, too. I would have been willing to buy new, but it seems none of the kitchen stores here in the Upper Valley carry flexible bowls, and my online search for "flexible mixing bowls" this small turned up dozens of businesses who sell only to dentists, orthodontists, or similar professionals.
Please reply offline if you can help. Thanks,
