New to sculpting. Will this product hold detail unfired to make molds from a variety of molding materials?

It will shrink as it dries out. Also, once dry, it will be fragile. It would be best to fire it if you want to make molds from it.

I prime everything w/ acrylic undercoat. I can't imagine ur casting such large items that u can't do it by hand.

The short answer is yes. The issue comes in on clay is the complexity of the mold and the ability to remove particulates from the mold once completed. For clay I usually make an alginate negative and then a plaster or dental stone positive that I then make my rubber mold from. The alginate does a great job in retaining the detail from the original that is translated to the stone. As far as release agent you can use a standard release or just an aerosol cooking spray (Pam or whatever). Some have used things like vaseline but I don't like the thickness as it is hard to keep it from pooling in crevices and hard to get out and may interfere with detail. But if your part is smoother you can apply a little to your hands, warm it up by rubbing together and apply a very thin layer and that will work as well.

To be on the safe side, I would suggest using some sort of release (thin film...residual amount... of Vaseline should be fine). You could always do a small test piece before you cast your actual project.

I forgot mention that the individual molds are attached to the top with aluminum. It's sturdy and isn't going to fall apart any time soon. Totally worth the money.

Don't try. Ive used both and Both form with heat so even if they don't fuse there will be serious deformation bordering on pointless. Instant mold is great for epoxy putty(I use it for gunpla parts, duping custom Lego elements, replicating broken items(etc.)) and the occasional resin cast if its simple and low detail. Sorry for going off topic. I wouldn't recommend it.

If you've made your mold I would suggest finding out how much water it holds, then estimating that volume compared to the kit. I have embedded scrap to stretch the casting resin volume, but it will show unless a partial, cured pour keeps the scrap from touching outer surfaces.

Yes, you can. I have done it several times with highly detailed pieces, and they turned out wonderfully! The resin just popped right out with no problem/residue left, so I was able to use the same mold multiple times.

Yes, thats the clay i use when making a piece. Just be sure to put a coat of the clear spray to seal it or the mold will tear your original apart and you'll have to scrub your mold. :) hope this helps and good luck on your work!

Yes to all questions. Have used it a lot as a mold for home made caramel, never a problem.

I love this little machine, but maybe not the best choice for what it sounds like you are trying to do. As others have said, it would be real easy to over sand and ruin the profile of moldings. To remove paint from molding, I would probably use a heat gun and detail scraper. I think that will give you better ability to remove paint without damaging the profile. Additionally, if the paint is thick, the small sandpaper pads this uses will load up quickly and you will go through a lot of them.

Absolutely! I find it particularly useful in concave shaping. It certainly can be used in a convex scenario such as in long flowing curves of an abstract form but I think it is more at home digging in. Happy sculpting!!

It probably can but it is a little porous. Its slightly fragile but will work in a pinch. When you pulled apart the mold it might shatter or break into smaller pieces. If you have a choice I would pick something more durable. this is better used for something like pouring into a cast and set in shapes for children to paint or artistic projects. I used it for a mosaic table top and had issues with corners flaking and it easily chipped. hope this helps!!

I used plasticine to sculpt a mask, then used the silicone to make a mold from it. It works fine, the smooth-on is a liquid so you pour it over the clay and let it dry. I had no problems with the 4 masks I did with it.

I've been using the resin to cast from molds about 1/16" to 2" deep. It actually works better on thicker pieces, so give it a try.

I'm not 100% sure what to tell you... it really depends on what you are doing...I make 3-D surfboards, snowboards and skateboards using bake-able Sculpey clay. For the parts of the board that I use the clay on, I absolutely use the "Sculpey glaze" but for the rest of the board I just use a polyurethane or exterior gloss varnish depending on whether it is meant for indoor or out door. Best bet is to use the recommended product for the medium. There is nothing worse than creating something great, and then "F-in" it up because you did not use the materials which were recommended! Hope this helps.

I used 1 pound of melting chocolate for about 5 different molds of all sizes and I ended up with well over 60 molds. It will make quite a bit. And the boots stayed awesome. I can't give you an exact amount that it makes, but you should easily get at least 80-100.
