How To Remove Polymer Clay From Silicon Molds 

Thanks, i almost clicked out

Terima Kasih

sorry to be offtopic but does someone know a way to log back into an instagram account..? I somehow forgot the account password. I love any tricks you can give me

@Beau Kayson instablaster ;)

@Rowan Kole Thanks so much for your reply. I found the site through google and I'm in the hacking process atm. Seems to take quite some time so I will get back to you later when my account password hopefully is recovered.

@Rowan Kole it worked and I actually got access to my account again. I am so happy:D Thanks so much you really help me out!

@Beau Kayson No problem :)

Thank you so much for the kind words! I really appreciate you taking the time to post them! 💖💖💖

Thank you so much for taking the time to pop in here and say that! It is appreciated! 💖

i was just about to say the same. about 10 minutes in the freezer really helps 😊

+Bel Ban and +Linda Cronk Good tips!

+PolymerClayTutor thanks for your tip too!

for how long?

Some miniatures artists make a mixture of PC & Liquid PC called 'Goop' in order to fill tiny & delicate stencils on a tile. You may get better 'lace' this way - Angie Scarr demonstrates it in some of her miniature flower videos. Good luck.

Glad it helped! 💖

I saw a video that layered putting the clay in. She put a little bit in. Got a ball tool and pushed the clay down. Then added more. Hope that makes sense lol

+SkulpTools SkulpterAz I'll just give you the same answer I gave Allison Merit below: "You can bake in some molds, but I prefer not to because, you can only bake one mold at a time, plus sometimes you haven't done it perfectly and it is a waste to bake something that isn't perfectly molded."

Nelson Darwin Pak Tech hi there, if you are referring to how polymer clay feels when it is baked, then it depends on how it is finished. If it is sanded and buffed it can feel like Stone though it won't be heavy or cold. If it's waxed or covered in a varnish it will feel like wood or ceramic. Or if you give it a suede-like finish it can feel like Fabric or paper. But basically it is a plastic so it mostly feels like plastic.

Yeah you can put a leaf through your pasta machine as long as it is a soft one. A thick branch-y one may push your rollers out of alignment. I wouldn't bother running it through the machine though, since in most cases it will just tear the clay. If it were me, I would just press it in to the clay and use an acrylic roller instead.

It’s a “glass cutting mat”. I found it on Amazon. I know it’s been 2 years since your comment, but in case it’s still helpful, or helpful to others. I went back and forth between buying this item and buying a basic white ceramic tile from the hardware store (which can also go in the oven and is WAY cheaper), but eventually I decided on this cutting board because of the graph lines. Also it’s super cheap to buy silicon mats (meant for baking) to put under the clay pieces before baking them on a cookie sheet.

Thanks for the info? The Armor All doesn't leave grease marks on the molded item?

With a clay blade slipped underneath.

There are so many kinds of molds out there, so I would have to see it to know for sure, but you certainly could try putting clay in your mold and see how your clay comes out. If you plan to bake in the mold though, definitely find out if your mold is heat safe though. Some silicone molds made for ice cubes for example, might melt in the oven. Here is a video with some different types of silicone molds that might answer your question better: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Lb_zlFoIZvY.html

Hi Robin, I'm still here. Oil isn't really a good choice because it tends to soften the clay and make it sticky. A dry powder, like cornstarch or tapioca starch works better for releasing polymer clay from molds. Water also works as a release for many brands of polymer clay but some brands like Fimo and Cernit, it also makes it sticky. Silicone, usually doesn't need a release though, as long as it is nice and clean.

You're the best!

a while ago she said they were from a hardware store, for nuts and bolts, etc. hope that helps.

+Bel Ban Yeah you can find them at places like Canadian Tire here in Canada, and Harbor Freight in the States. There are tons of places online too even amazon. They are called parts bins if you're during a search for them.

Slight problem though. You might distort the cast and the mould if you place a sheet on the top and press down. Placing it face down supports the cast and ensures even pressure into the clay, and a good bond with the mould.

Glad to be of help to you! Yes I just used the shinyglass surface to pull the clay from the mold.

Don't be jealous... it took me years to build up my supplies. You will eventually get all that you need/want too.

+Sifoutv Pottery Thank you. Could you please write out a different comment each time you leave one? Because you use the exact same words every time you comment on my videos, your comments keep going to my spam filter. Thanks a lot!

+Yannarra No... if you use a release, it is really hard to keep the clay from popping out while you're pushing it into the mold and you can't get the fine detail that you want.

Oho.. makes sense... Thanks! :)

Did you find the answer? This is my question too.

I tried just putting the clay in the mould and then baking it. And that works perfectly. The moulds I have can take the heat and it insures that the clay is perfect when taken out of the mould. So if your moulds can take high temperatures then I think it's the best way to work with the clay :)

haha I asked this question to myself while watching the videos, because I always bake my clay in the mould so it turns out perfectly ^^

Fishnetfreud TY! I was just going to type this exact question! It makes sense to bake the clay into the molds, then remove it when it is hard! I *DO* wonder if making molds from silicone sealants, etc. can also handle the heat? I suppose if making any molds detailed, I should be sure that weather I use a pre-made silicone mold mixture, or create my own, that making sure it can handle baking before even creating the mold would save $ and hassles down the road! I see you tried it in a mold that can handle the heat fine, without distortions, and seems it came out perfect! :) Using liquid Fimo (or similar bake-set clays) would be really an advantage to obtain micro details in a mold! Being sure to not shake the liquid clay, but stir instead, tapping out, and using a sharp, thin tool or wire to be sure no bubbles remain in the mold after pouring & before baking, would be advantageous as well! Thank you for asking & answering my question! I am not huge into clay or pottery, yet would like to create embellishments for creating one-of-a-kind multimedia journals, and when I make a certain type of embellishment, or decoration, that I REALLY like, I would like to be able to reproduce it. I also like making miniatures for shadowboxes, doll houses for the girls & castles for boys and girls. I've created a few things things I wish I had made molds for, as they were VERY detailed, and creating them took a long time, thus my starting to play with a bake-set clay. Plaster is too brittle for some of the tiny pieces, and absorbs the paints too readily for some of the details to show up well, so I'm going to give Fimo a try. I could probably create these in ceramics, yet making duplicates would likely require using a finely-ground plaster for making a slip mold, and would likely be more difficult! Sadly, it would also not be possible to create in a clear medium if done in ceramics (although I COULD do them in glass, and have created a few that way (via making a porcelain, or similar clay, using kiln wash over the mold, then melting glass into the mold in a kiln... This, unfortunately, takes a LOT of time, a LOT of experimenting with glass thicknesses, COE considerations (different COEs of glass perform differently when you're working with very fine tiny details, thus you can have thin glass crack, shatter or explode in the kiln, so testing different firing schedules, a lot of electricity, testing different glass that performs differently, watching colors {especially yellows, reds and striker glass {glass that changes colors when fired}). Thanks again! :)

Alexa Gates TY Alexa! I had the same question! Good to know we can bake these in their molds, as long as the molds can safely be used for baking! :)

I'm not sure what you're asking, didn't you watch the video?

+Daniella Uribe Even if the mold is bakeable, partially cooking your piece will not work because the clay will be very brittle and just break. The clay either needs to be raw or completely cured to get it out of the mold without breaking it.

If the mould is heat resistant to a temperature above the curing temperature, you can bake the cast in the mould. That's something you can check when you buy your silicone moulds.

rubbing alcohol will help break it down.

+BlackCat2 Didn't know you could glass fuse in these kinds of molds. Sounds cool!

PolymerClayTutor well you can't put the molds into the kiln but you freeze the glass paste in the mold and then pop it out of the mold. Then that goes into the kiln after a little warm up to avoid thermal shock. You have to have the timing just right though or the details will start to blend into the piece instead of being raised.

+BlackCat2 Wow! How cool is that! Thanks for sharing that info. I had no idea about that craft!

PolymerClayTutor You are most welcome. :) I am into several different things like resin, clay, glass fusing, kumihimo, woodworking etc. I like variety I guess. :) Also temperature is as important as timing for the firing process in the kiln. I forgot to mention that part. Also you have to make the glass paste from a glass powder. Look up "freeze fusing" if you want to learn more.

+Alison Merritt You can bake in some molds, but I prefer not to because, you can only bake one mold at a time, plus sometimes you haven't done it perfectly and it is a waste to bake something that isn't perfectly molded.

If you make the mold out of polymer clay, then you can not bake new polymer clay in that mold, otherwise they will bond together. But if you make your mold out of silicone that can handle being baked at the same temp as your clay, then you can bake in it. I have a video in my channel that shows you how to make molds using a 2 part Silicone Putty that you can bake in. I suggest you watch that for more info. Good luck!

@@PolymerClayTutor thank u so much❤

+brikhouse22 Using a powder like cornstarch is perfectly fine. Put it on your fingers rather than the mold though, since it is your fingers that the clay keeps sticking to and pulling from the mold.

Some molds you can bake in and some you can't. But also, if you bake in the mold, you can't see how it turned out, before you bake it. If you didn't press the clay into the mold well enough and there are air pockets or missed spots, then you have wasted the piece by baking it. The other thing about not baking in the mold is you can bake more pieces at once if you unmold them first. But if your mold is oven safe and you prefer to bake in the mold that is perfectly fine. You do you! 🙂

@@PolymerClayTutor well all of that makes perfect sense..I am glad I asked an expert. Thank you so much! Enjoyed your video!

Yes freezing can definitely help! Thanks for sharing!

@@PolymerClayTutor for how long must you freeze the clay? any temperature required?

So don't watch it

@@roxylee9560 Not watching doesn't change the fact stated in the main comment.

Who cares? I came for the technique, not the performance.

How's your Special K this morning?

Not enough listening?

dont be so rude ..just bugger off

Looks like the attention span of RU-vid users is falling. How the hell did you manage at school or college? Lol.
