casting cleanup question

Posted in Custom Workstation

I made teh mistake of not coating the inside of my mixing cups with release agent. Anyone have suggestions of a good way to clean the RTV mix out of them?

I made this one bigger than it needed to be and didn't get the release agent on thick enough so the 2 half stuck together. I can recycle it by using the pieces to fill in around my next one. I got a kit from micromark that included 6 mixing cups that seem to be pretty impervious to anything sticking to them a lot. I have a head I want to copy but the hair is too complex. I mostly want to use this for making nice versions of my toy prototypes.

I'm just starting to get a handle on casting. I was having a lot of trouble just making decent molds.

I would suggest using disposable cups though. lot less PIA and mess. unless you're making really big molds / casts.

actually the ones I have the fully mixed rtv in cleaned up good. Sadly the one that has the white half of the 2 part rtv is a gooey mess. I might add a tiny bit of the other half and mix it and let it cure and peal it off. I know when I pour the resin it'll be a lost cause. Sadly my first try ended in disaster and wasted a lot of material but what did turn out looked nice. I'm trying to make a mold of a wolf.

I'm pretty sure your current mixing cups are beyond help.
