This was so straightforward and helpful. I may be 7 years late in seeing it, but I would still like to thank you, even though you are unlikely to see it! Great tutorial and much appreciated. Many thanks ❤

[@SandyHuntress]

Hi Apple, Thanks so much for letting me know you found the video helpful! Happy creating 🙂

[@Haydenmonroewood]

THANK YOU! Honestly! I’ve searched 2 days for a video to tell me how to do this. Finally! Thank you again!

[@SandyHuntress]

I'm so glad I was able to help you, Barbi! Happy creating :-)

[@ZahrarKaiser]

This was so easy and helpful. Thank you so much. You make such a good teacher❤️

[@SandyHuntress]

Thank you for the kind words and for letting me know you found the video helpful. 😀 Happy creating!

[@amandajones6481]

Hi Sandy, thank you for this wonderful video tutorial. I love how the registration holes work when you put the 2 parts of the mold together. What a great idea ❤, love from Amanda in Australia xox

[@SandyHuntress]

You are very welcome, Amanda! Thanks for letting me know you found the video helpful. 🙂

I can't stop laughing about the cat hair because that is so my house when I try to work with something lol. Thanks for the tutorial!

[@SandyHuntress]

I know some people don’t allow their cats in the studio, but I enjoy their company too much and would rather deal with the cat hair. 😹

super duper helpful, thank you!

@@SandyHuntress I have that epoxy silicon also im in the process of making a two part mold in which im going to inject hot glue into it to make small parts that's all right isn't it?

[@tyedyelover7]

Very helpful! I am casting small stones but want to have a eyelet screw on an end essentially making a charm - with your video I am feeling very confident that I will succeed at this project.

[@SandyHuntress]

Hooray for confidence! I'm so glad the video was helpful. Happy creating

[@1994abbygirl]

I have never seen this mold stuff.. I can think of several things I'd like to make a mold out of! Thanks! Thumbs up!!

[@SandyHuntress]

It's fun stuff to play with, it opens so many possibilities!

[@EriAikawadiary]

This is what I’ve looking for! thank you! I wonder if i could make a mold from a barbie boots and make it into keychains. i’m worried that the hole in the boots would be quite difficult to make a cast.

[@SandyHuntress]

I don't know that polymer clay would be the best material for a shape like that. The deep hole would be problematic. Or you could try making a mold with pourable silicone, then use a pourable materials to make a cast.

[@EriAikawadiary]

@@SandyHuntress thank you so much for your insight! I was debating on silicone molds and resin. but I heard resin is toxic? I might make the holes of the boots a little shallow and maybe stick a peg in it and also use a peg in the cast while I mold the boots. does that make sense?

[@karinasulger7829]

awesome tutorial ........ty Sandy!!! was nice to see how to make a 2 part mold ... as ive never tried that one ... so will def be trying that one !!! ty again

[@vinnydabarber]

Wow, I love that! You make it look so easy!

[@im8555]

Thank you for this. I was trying to find a way to use double sided chess molds and now I understand how too.

[@SandyHuntress]

I'm so glad to hear this was helpful to you!

[@debraroberts1139]

Hi, great tutorial, thank you. Is this suitable for silver metal clay?

[@SandyHuntress]

Good question! Yes, you can definitely use molds with any type of metal clay. Happy creating!

[@blundin4165]

Great little video! Would this method work when casting in plaster as well?

[@SandyHuntress]

Thanks, glad you like the video! I’ve never worked with plaster, so I really have no idea how it would work with this type of mold. Isn’t plaster kind of runny? If it is, I think it wouldn’t work.

[@blundin4165]

@@SandyHuntress Hm...yes, definitely runny initially... I'll give it a try and let you know! 😃

[@jacquelineshawdeyoung6918]

Do you have any videos for a double mold that you can pour plaster into? Thank you

[@SandyHuntress]

I'm sorry, no, I don't. Since, unlike clay, plaster flows, that uses a very different technique.

[@janetsmith9380]

very good video. thank you so much. very helpful...

[@SandyHuntress]

I'm so glad to hear it was helpful, Janet!

[@deannwilson3553]

Can resin be used with those molds?

[@SandyHuntress]

Yes, they can! They are silicone so no mold release is needed.

[@kaiyodei]

can you do this with the silicone and cornstarch? is there a way to do putty and resin?

[@SandyHuntress]

Sorry, I don't know anything about silicone and cornstarch. I would imagine you just need to find a way to keep the two pieces from sticking together and it would work. As far as using resin, I'm not sure how you'd do that. Perhaps mold and cure one half, then fill the other half and place the already cured half on top? It would take some experimenting.

[@Marisuki94]

This was so helpful to watch, I only considered two parts liquid silicone molds to try this procedure and it felt too complicated since my pieces are not that big or intrincate, but this way seems easier and I feel it can work for me! I'm definitely going to try this, I may come back to update on my results ^^ Thank you for the video!

[@SandyHuntress]

I’m so glad to know you found this helpful! Yes, please let me know how it works out for you.

[@designsbydawn976]

Thank you for sharing! What brand of silicon do you use and where do you get it?

[@SandyHuntress]

Dawn, I always write a blog post where I have supply lists and product links. You'll be able to find that blog post linked in the video description as well as in the upper right corner of the video.

Thanks, Andrew.

[@kathryncastanares3205]

Tfs! I find this to be my favorite of the two molding putties ive tried (the yellow amazing mold putty and this one) as far as strength goes. however, i have a bit of trouble with this setting up during the mixing process even tho there are still quite a bit of white swirls left unmixed. I am very careful about having the correct ratio and being careful to mix quickly. Its so strange as it doesn't happen every time, but quite a few times and I've wasted quite a bit of my putty:( I wonder if anyone else has ever had this happen even once and/or if anyone knows what i could be doing wrong. I really like this putty's ability to catch great detail and hold up to quite a bit of stretching, being so durable.

[@SandyHuntress]

That does sound annoying, Kathryn, the stuff is pricey enough without it kicking off early on you! Was it particularly warm or humid on the day you had problems? I have to wonder if weather was a factor, or if maybe different batches give different results? Are you mixing vigorously and creating a lot of friction when you combine the two? The heat created will cause it to set up faster.

[@sedsworld1672]

May I trouble you for part I on how to make a one part mold? Please and thank you 😊.

Is it possible to use other clays bodies?

[@SandyHuntress]

Sorry, Sara, but I don't understand what you mean.

[@sarapeace7570]

@@SandyHuntress Hi Sandy I am a Potter and I work with clay like earthenware and stoneware to make ceramics. Of late I have been making pendants and that is why I asked if I can use your type of molds with my clay. I would like to use your molds because they are cost effective compared to plaster ones. Thanks. Thanks.

[@sarapeace7570]

Hello SandyI normally work with stoneware in ceramics. I use it to make pendants. In order to reproduce work I am trying to make molds using plaster of paris. So what I wanted to know is can I use this type of clay instead of polymer clay in the molds you make. Thank you for the reply.Sara

[@SandyHuntress]

@@sarapeace7570 That's a good question, Sara. I'm not real familiar with earthen clays, but I don't see why it wouldn't work. The molding material I show is silicone, and kinda pricey, so I'm not sure that they would be more cost effective than plaster of paris. You'd have to do some experimenting and cost checking. Let us know your results when you do!

[@sarapeace7570]

@@SandyHuntress Thanks for the reply.

[@denaferreira9197]

how do I pour resin into one of these

[@SandyHuntress]

I don't think resin would work for this kind of mold. You might look up how to make silicone molds if you want to mold a 3D object and then pour in resin.

[@kerry2373]

You can do this with 100% silcone mixed with cornstarch
