Two years gone by, hope you read this message. You are a very good teacher. You give good attention to detail and your voice is pleasant and easy listening. Thank you.
thank you for the kind words
It's silly, but I liked your musical score during the video.
I'm sure you already know what a natural teacher you are. Skills.
very thorough tutorial. a gem in the educational category of youtube.
I’ve been looking at countless videos
On how to make a mold of my clay sculpture and this by far has to be the best in depth tutorial. Thank you
I so appreciate how generous you are with teaching us and also your thoroughness. Brilliant!
You are so inspiring, and the background music is so soothing for such a delicate process.
Thanks for the tutorial. I started making vulcanized rubber molds for jewelry and small sculpture. The world changed, thank you for new help .
it's a very good channel to learn about sculpting and stuffs.actually you're a good teacher.
Runner bands is the same way I do moulds for the moulds that I use/make for lost wax casting in jewellery making.
Clicked initially for the content, and stayed for that and the Demon Hunter mount in the introduction.
Thank you SO MUCH FOR THIS!!!! YOU ROCK BRO!
sincerely thank you for your content.
great work my man!
Man! The music is making this epic!
What a great tutorial, thank you!
I love the improvisation. Thank you for sharing!
Mold max 30 is tin cure as opposed to platinum and solves the uncured problem. It cures on unprimed 3D printing resin. Another advantage is part B is very liquid and it makes it easier to mix.
Excellent video. Super informative!
The video was great and I love every single story you've made up for me.
Brilliant work, BTW!!
23:00 I cut a bit of each mold and keep it on hand to displace new molds so I don't need to mix a new pot. love the video
Excellent how-to video, very handy for my own sculpting/molding adventures! :-)
Great video ... thanks for posting.
Thankyou ! i'm excited to try making a mold now
Thanks for this, what a great tutorial!
Cheers Josh. Great video as always.
This was very informative. Right now I have lots of time, and this helps fill it! Thank You.
Thank you! I’ve been selling my sculptures lately and making molds has been on my mind....even though I’m a little nervous because of the size...like a house plant size...we will see how it goes! Very informative and thank you for breaking down the steps so my brain understands!
Great info and breakdown
Thanks so much. Hope you can make more of this series.
The quality and content of your videos is really good. The animations were really helpful at getting your point across and your explanations were great
Just gone for a molding and resin course, so thanks for your insite😍 I am like a kid in a candy store can't wait to start 🕺❣
Under appreciated video thanks so much for the price break down and making this as accessible to viewer as possible
Thank you so much for the information.
Also, man, your dark room looks amazing!
This is phenomenal., I've had an itch to do this for a year.your the best and will be starting my projects soon.Thank you!!!
Thank you for the info, plus you are funny too 🥰
Loved the solution for not having enough silicone for both, I will have to remember that one! 🤗💜
Great video. I'm learning a lot from your tutorials (new to sculpting). Acrylic paint and resin paint dyes work as well, when coloring resin. I've even used food coloring before (experimenting), and it worked flawlessly.
Great video, your explanation and graphic presentation of undercuts was amazing, the best by far
Very nicely done. I gotta tell ya I really like the background music
Thanks for the info!!!
very informative video. thank you
Yours was the first and only book I read on kindle, I'm a big fantasy book fan but being of a certain age my lamp oil is well low so I listen to audio books. Oh and I do love your videos.
I have yet to cast my first sculpt, but boy im glad you showed thatthing where part A has all these lumps in it and how you got them out, great tip!!!
Every time he says "Bomark" all I hear is "Bokrug" hahaha!
Just wat i need it😁 thanks
If your not in a hurry ..ive found that exterior latex paint sticks them to the boards good
I had some success using a silicone dye as well as less catalyst (for condensation-curing silicone only!!! Do not use this method for 1:1 mix!!!) To increase pot life. From about 30 minutes (Xinus RM910) to about 2 hour, and demold time to about 4 days(!)
During that time you can do all sorts of things like vacuuming out the mix so it doesn't have air bubbles or pressure-potting it.
Oh and the dye is just used as an indicator to show that the mix is uniform in formulation, and that when you can't see the streaks it is ready to be used.
Great tutorial! I love that you showed how to recover from things like not having enough mold material.
Given that you seemed to have more that the minimum half inch around the head, could you have used a ring clamp or band clamp to bring the sides in slightly? Obviously you don't want to do it close to the base for fear of popping your seal. But up near the top this might be a solution. If the cup won't flex enough on its own, possibly make a small cut to allow it to fold in slightly.
Thank you.
Oh, I just ordered my first silicone and resin yesterday :) Right on time! Thank you so much for all this information, there is a lot of videos about mold making, but your is exceptionally informative and beginner friendly. As all your tutorials. I'm a fan:D
Also, I have a question for you guys - can you make a mold out of water based material? I would like to make a lot of various sized crystals for sculpture, and I had an idea of making molds out of borax crystals - but they are mostly water. When I receive my silicone I will experiment with that and just see what will happen, but maybe some of you had experience with something similar?
Love this! Damn bubble air! Every time they break our dreams hahahaha
Tap Plastic has a good tip for getting rid of bubbles in silicone - has to do with a small hole in the pouring cup and positioning at the edge of the table.
Love your fixes for VERY common problems. Why do you prefer talcum powder over mould release spray?
you can reuse cured silicone, cut it up and throw it in the new mold as a filler.
BRILLIANT
You are an amazing teacher! Your literally the only one on CZcams that goes into depth about what your doing and how your doing it when it comes to arts and crafts
I have a question
I don’t know how else to reach you, but do you know the process and what I would need to turn a sculpture into polystone?
I know that I will need the mild for the sculpture but I don’t know what the next steps are?
Hope to hear from you but either way you have my subscription and support 👍
thanks for the kind words! Unfortunately I've never cast with polystone, but from a little bit of research it appears to just be resin with some kind of powder mixed into it, so it should work pretty much the same way as what I did in this video. You mix it up and pour it in the mold. The only thing you'll want to double check is what kind of mold rubber you need. Polystone might work with the cheaper tin-based rubber, or may need to be platinum-based. If I were you I'd call or email SmoothOn and ask them. They've always been very helpful whenever I reach out to them. www.smooth-on.com/howto/sculpture-art-casting/
@@JoshForeman thank you so much for getting back to me my friend, I will get in touch with them, keep posting these videos! Thanks again 👍👍
this is the first video i've seen that mentions the tip to pre-strain the silicone. 18:00. also, another good tip about cleaning the container rims. 18:55
Josh you could have used a rubberband around the plastic cup to squeeze it enough to push/displace the silicon to cover that little bit of the sculpture that was showing.
Great tip! Thanks!
I was going to comment that when you run out of rubber, you can add filler to the sides to displace. But you did that. Lol. It probably was good that you ran out, because that's a good tip for beginners. Rubber is expensive.
You’re very sweet and nice! Thank you so much for this
I just dove into the world of resin casting and this was quite helpful. Thanks! A couple of questions:
1. You mentioned "filling in" some errors in your finished cast. What do you use to fill missing bits?
2. I made my first cast of a large skull I sculpted using Smooth-Cast 300, which hardened incredibly fast, btw. D'oh! Before I mixed A and B, I added a generous squirt of black dye, but when my casting cured it was almost completely white. Any reason the black color was almost non-existent?
Bondo is a good filler but VERY smelly, so I usually use Epoxie Clay. I have a video about Epoxy sculpting. Since I don't know what dye you used it's hard to say. Smoothon makes a special pigment for resin called So-Strong that goes pretty far. But in general, if you want really black resin you should just buy the black resin they sell. Or the semi-transparent stuff that's designed to be colored.
How to make a mold of beads such as skull bead for Paracord sir? Please guide me to make it coz I'm very inspired by what you're doing...
Lol that door squeak. lol it's Haunted.
Hey, nice lesson!
Can i pour Pewter using this mold method ?
Thanks for share your knowledge!
I don't know about pewter but I do know that there are some low melt alloys that are compatible with high grade silicone since their melting point is well below the degradation temperature of silicone.
Hey I am trying to make molds of 1/2 scale open hands-spread fingers, but I haven't been very succesful. Do you have a video that shows how to do that ?
This is awesome, Josh. I really enjoyed learning from you. I restore antique radios and record players and I am learning to make reproduction knobs and other parts. Your relaxed presentation was easy to follow and emulate. I have to know...what is the music? It's wonderful and I would like to buy it, if I can. Thanks again. Cheers! Michael
Depends on the part of the video you're referring to. The music at the start and finish was custom made by a friend. The stuff in the middle is Music by Scott Buckley www.scottbuckley.com.au/
Did you think of using a vacuum pot to deal with the undercuts? It's probably in another video.
Yeah, I generally do, but wanted to keep this video beginner-friendly.
Thanks…I don’t know why, but I am so afraid of the molding process…I am gointo try it…thanks…I love sculpting with monster clay, but would love to preserve my sculpture…😬.
Do I really need to prime my sculpture? I feel like I might loose small details around the eyes and stuff. What could happen if I don't prime it?
I've never noticed a difference to be honest. But perhaps people with a keener eye could. Either way, you'll need to do extra tests to make sure your resin and silicone are compatible if you decide you don't want to prime.
Great video, thank you! question, can you use this mold to make candles?
Yep!
@@JoshForeman thank you so much! ordering everything now !!
how do you fill in the bubbles? apoxie sculpt or something like that? (perhaps the propoxie in the list..?)
It really depends on the specifics. I usually use apoxie sculpt. But I'll be doing a future video on the topic! :)
@@JoshForeman thank you. I look forward to it.
why don´t let the rubber harden and pour the missing amount to fill in? with trollfactory that works pretty good.
In my case it's because I ran out of rubber.
Hey Josh. I've been looking for a good video on what a sculptor should keep in mind when sculpting, and final prepping a piece, when planning to bronze it, or stainless. As well as what to sculpt in. Is plain old modelling clay the best thing to handover to the foundry? I can't find a video or even a good article, is that because there is nothing to know? Just sculpt it, and hand it over?? Any help much appreciated. ty peace
p.s. you should bulk up on rubber if it's not synthetic. Rubber price is about balloon. Industry is really stressed. pc
I've never got any of my pieces cast in metal so I'm not sure about the details. I would contact some art foundries in your area and ask them.
Where's part 2?
I will post it as soon as I'm good enough!
any tips for using and mixing powdered pigments in epoxy"?
My pro tip is: don't bother. I've never been able to achieve anything with them that's better than just painting with metalic paints. :(
@@JoshForeman HAHA dang it that's what I thought, I appreciate the response from the pro though.
If you know, is it worth to use pk pro resin and silicone casting?
I'm not familiar with those products, sorry
Addition cure rubbers won't cure on surfaces containing sulfur where as condensation cure rubbers are not making them more user freindly.
i dont try to get fancy with maths (mostly because i suck at it) i just fill the mold with water to determine how much silicone i'll needs. and i always save leftover chunks of silicone for displacement if i need it.
Would it be possible to use this method to make a mold from a polymer clay sculpture?
Absolutely! Just make sure you've primed the sculpture. Some silicones won't set correctly with polymer clay. I recommend Army Painter spray paint primer.
Is there any issues with silicone, like do you need a vapor mask or just a well ventilated room?
I don't believe the liquid silicone has any toxic fumes, but as always, read the fine print! (I've never used a vapor mask, but I've also never used it in a small room.)
Hi! what about Blue Staff Molds to make a two - part mold?
I've never heard of that. Have you done molds this way? Is it a product?
I'm looking for a more durable/less brittle resin, like even plastic-like that I can use for outdoor sculptures. Does anyone have any recommendations? Thanks!
I would email or call SmoothOn and tell them what you're trying to do. They've always been super helpful for me with this kind of question.
What can I use for my porcelain full body sculpture...... I want to make a mold of just part of the body , yet I don’t want to ruin its delicate work it’s ..... primer is definitely out of the question. Is there something that I can protect my porcelain sculpture when doing molds ????
You don't need need a mold release or primer when molding porcelain. The urethane rubber will come off perfectly clean. Worse case scenario would be needing to run a paper towel with some denatured alcohol over the porcelain when you're done.
i have a question ...i need to make sculptures so i can make a mold out of them my bestie is the artiest and she will ship me the sculpture what is the best type of clay to use ? she doesn't have a kiln and will hold up to a mold being made from it ?
It really depends on what she's comfortable with. I have used polymer clay, Apoxie clay and 3D prints. Here's a series about Sculpey that might help. czcams.com/video/WlPYWe2bGUo/video.html
Are your miniature statues made of polymer? I’d not, what type of clay? I’m trying to do this with air dry clay for a project but I’m struggling with cracking of thin pieces of the piece, do you recommend a different type of clay?
This specific piece is a 3D print. But when sculpting traditionally I use polymer clay or apoxie sculpt. I've got videos about both of those you may want to check out.
@@JoshForeman thanks so much! I had started your clay 101 video and will definitely finish that today, I think I will start with polymer after this project!
I want to sculpt my own shoe box size creations and later make cement copies. Can somebody please tell me what type of clay is best used to make this type of mold? Thanks
Lot's of great info here: www.smooth-on.com/howto/concrete-casting/
Okay j have a question i can’t really get answered anywhere. I’m making a very simple sculpture but i don’t already have the sculpture ready so i can’t just make a silicon mold for it. I need to make the sculpture first. How do i go about doing that?? How did you make yours?
I make sculptures in two ways. I either sculpt them in clay, or a sculpt them digitally on the computer and then 3D print them. If you are just learning to sculpt I recommend my Sculpey 101 series. czcams.com/video/WlPYWe2bGUo/video.html
@@JoshForeman what I plan on making requires precision, so 3-D printer makes sense, I’m just not good at 3-D printing so layer lines are often visible And I don’t know how that would affect the final product
@@GiraffeKing04 That requires a lot of filling and sanding. I did that on this video if you want to see how I tackled it. czcams.com/video/LL86sNznshw/video.html
Is this method used for polymer clay objects, including the primer or would primer melt polymer clay?
Yes, I always prime my polymer clay sculpts before molding. However, there's a lot of primers out there, so the universal advice is to do a test on a scrap piece first to make sure your specific primer and clay play well together.
@@JoshForeman SCULPEY is the brand i use
@@gremics-gallery I've never seen a difference in material interactions between the different brands of polymer clay, but I have seen a difference in primer interactions with polymer clay. Most of the spraypaint primer I've used is fine. But you still need to test it first. Some kinds will stay tacky forever.
how do you make a mold that is smoother on the outside , your housing with the glue inside the seems as well as outside , makes the mold not look good. I am asking in the case of wanting to sculpt and then make a mold to sell of the sculpture? thank you in advance
You can spend as much time as you like to make the mothermold as beautiful and smooth as you like. It just takes more time and patience.
@@JoshForeman thank you so much for your speedy reply even though its 2 years later then you made the video. some people don't look back. thank you
@@sherryebersole1349 Always happy to help! There's a variety of channels that show a lot of different mold making techniques. Here's one that shows a very clean pro-looking mold. czcams.com/video/WME8R2-Ot8E/video.html
How to reuse rubber? Can we heat and melt
This kind of rubber mold material can not be re-used. There are some reusable rubber but I've never tested it myself. You can find them if you google "reusable mold making material"
Using this resin..are you able to paint it at all? Or are you stuck with the ugly brown?
They definitely get painted. Here's the collectables we make from them. www.amazon.com/Breath-Of-Life-Development-Scolla/dp/B097B6H76W?ref=hnd_adp_tp_2
Protip for insufficient rubber emergencies: Broken up chunks of old molds can displace a lot of volume without introducing chemicals that might affect the curing process
I wish I could be your (and intermediate family) friend irl 😢 and just help you make these things. (creepy comment concludes)
on a relevant note, I appreciate you showing us the mistakes and figuring out how to problem solve. (for us poor folk;)
Still working on summoning a horse from the land of Ice... lol
How do you fill in holes?
You'll have to be more specific. If you tell me the time on the video the holes are, I can be more helpful

can you mold your wig?
it Zbrush or replica from clay?
The original sculpture was made in Zbrush and 3D printed.
next time try squeeze the cup a little that'll displace the rubber enough to cover the top
Seen many casting videos, no one has explained this well🙏pranams. But disappointed to see the results😢
