shadrap1769 Posted January 24, 2008 Report Share Posted January 24, 2008 I recently made some Sculpey masters, which is pretty darn fun on it's own. I then baked the masters then coated them with PAM. I then submerged them into the POP with the top visible and let the POP set up for a day. Now it appears i'm not going to get the masters out of the POP. I was under the impression that the POP would shrink a little allowing me to remove the master. Where did I go wrong? thanks Quote Link to comment Share on other sites More sharing options...
Cthulhu Posted January 24, 2008 Report Share Posted January 24, 2008 Hi shadrap1769, The plaster probably didn't shrink as much sideways as it did vertically. If you use a rigind form like baked sculpey, make sure you include a handle of sorts to pull on in order to yank it out of the mold with pliers. Something like a bent paperclip or a couple of toothpicks might work, but if there are any overhanging areas, it'll be impossible to remove without either breaking part of the mold, or somehow digging out the sculpture. Next time, rather than baking the sculpy, keep it flexible or better yet, use oil-based clay (like Klean Klay) or wax (longhorn has a thread on this). These are maleable materials that you can easily pull out of a set mold. Or dig them out with a paper clip, if need be. Hope this helps.

nova Posted January 24, 2008 Report Share Posted January 24, 2008 I use sculpy clay a lot. I only baked it once and never did it again. I use it soft in the mold. It's a lot easier to get out of the mold especially if you have a complicated shape. www.novalures.com Quote Link to comment Share on other sites More sharing options...
Smallie Posted January 25, 2008 Report Share Posted January 25, 2008 If you don't bake the Sculpey, can you still glue it to the bottom of the mold box? Quote Link to comment Share on other sites More sharing options...
Cthulhu Posted January 25, 2008 Report Share Posted January 25, 2008 I don't put my masters in the bottom of the box. I pour the molding material first, then press the masters down into it. Takes a careful hand, but it's not too difficult. To make sure they're flush, you can use a piece of flat plastic (coffee can lid) or other material. Usually though, the master tends to stay down due to the viscosity of the molding material I use (Hydrostone). Quote Link to comment Share on other sites More sharing options...
nova Posted January 25, 2008 Report Share Posted January 25, 2008 Yes you can glue the scullpy to the bottom. www.novalures.com Quote Link to comment Share on other sites More sharing options...
shadrap1769 Posted January 25, 2008 Author Report Share Posted January 25, 2008 My thought was to not bake the sculpey but keeping it soft will ruin the original master. However I guess once I have a mold I can pour some plastic to make a new master and keep it in case the mold breaks. Thanks. Quote Link to comment Share on other sites More sharing options...
nova Posted January 25, 2008 Report Share Posted January 25, 2008 That's the only drawback. Once the first mold is done; so is your master. At that point; if you want to make more molds; you keep your first mold as the master and pour plastic baits from it to make other molds. www.novalures.com Quote Link to comment Share on other sites More sharing options...
Cthulhu Posted January 25, 2008 Report Share Posted January 25, 2008 Another option is to make some tougher casts from the mold after the master is removed and/or destroyed. You can use silicone or liquid latex to make first generation casts that can then be used to make multiple molds. Quote Link to comment Share on other sites More sharing options...
