- Last week I poured sculpting wax into a silicone mold and it stuck like glue. That has never happened before so this video is an investigation into what could have caused it.
This video is Part 2. Watch Part 1 of the series here:
• Recasting A Resin Mini...
Here is a list of suppliers for many of the materials I use in my videos:

Do you have a project to suggest for the channel?
Here’s a .pdf with everything you need to know:

Normally, on this channel: "sticky wax! :D "
Today, on this channel: "sticky wax! D: "
I realize that the wax caused a bit of a detour on this project, but I'm still hoping to see you resculpt the wax figure and make a new one.
Amazing how it started out with "now let's cast this miniature in wax so we can customize it further" and then we're hit with a major plot twist followed by a deep, dark mystery.
I'd add one more precaution (since wiping with paint thinner seemed to help too) painters have lots of complaints about reapers mold release. Washing the model with some dish soap or simple green before making your mold will help keep it clean from contamination
When removing wax I tend to put it in boiling water that allows the wax to melt and float to the top.
I’ll have to give that method a try! Thanks.
Good idea! I was wondering whether there was a solvent that would remove the wax without damaging the rubber. Can't believe I overlooked good old-fashioned water!
This was like watching a good episode of MythBusters. Methodical, thorough. You are a master craftsman, that was a pleasure to watch.
Thanks Nils, I appreciate it.
So when people say "Nothing sticks to silicone but silicone", well.......
Feels like I dodged a bullet by adding some mold release filler together with carnauba wax. I'll remember to keep adding them when I have carnauba as an ingredient for my wax mixes.
What material do you use for your filler?
As soon as I saw the wax sticking to the outside of the mold, I suspected it was a contaminant in the wax, but I thought it was something introduced by the containers it was melted in!
Yeah, since he said it was exactly his usual wax, I assumed it had been something left in the mould by the previous batch of resin, or even by the original model itself.
Yeah, in the old video people assumed it might have had something to do with the plasticizers in the PVC model
Thanks for sharing your expertise with us, I love this channel. I recently used (abused) some concepts I saw here to make cut molds for chocolate, for my girlfriend's baking project. It turned out pretty great despite tempering chocolate being a rabbit hole all on its own!
My daughter is a pastry chef and she knows well the horrors of tempering chocolate! I feel you pain. Happy to hear your casting project came out well.
You should've just simply tossed the block into a pot of hot water, of course off the flame. The wax would've melted and floated to the surface! Oh, and sorry for the trivial pronunciation correction Robert, but in Brazil, the proper way to say the word for this wax is not as: Kar-KNOB-bah (knob lol) ........but as: Kar-KNOW-bah
excellent video. your experience knowledge and analysis of the problem shines thtough!!!
Hi Robert, I'm just about to start getting into using wax as a medium for sculpting and mold making and wanted to say that discovering your channel and videos during my research has been a godsend! Thank you very much, always informative, entertaining and well made. Deconstructing what goes wrong was particularly fun and insightful in this video and in this hobby that seems just as important, if not more so, than what goes right!
Well you didn't say anything about using carnauba wax in the first video. Of course it was the carnauba wax. What else could it possibly be, as if I would know that it was or wasn't. But thanks to Google I can now spell "carnauba" correctly. Sounds like mystery solved.
Bob loves sticky wax so much he makes it by accident
Normally it is my best friend. This time, not so much. 😀
Im cracking up ahahah I work with resin on the daily and still mix 2 part Bs! Thanks for sharing this mystery
Don’t you absolutely hate it when that happens? Makes me mental!
It's in the material! It has it happen to me alot now!
I understand you got the carnauba to stick but I’ve had this problem before with multiple wax recipes and then had successfully results with the same wax. I found the temp of my wax was too hot.
I might be rosin as well, that’s the sticky component of sticky wax, and I’ve seen a lot of recipes of casting/modeling wax containing it in small amounts.
Thanks for clarification, all lessons learned.
I remember the diaper days 😆 🤣
when cleaning out the mold, could you have put the mold in a bucket of hot water, and let the wax float to the top?
A couple of people have recommended that process here in the comments. I’m inclined to try it.
I used carnauba in my university degree, we used it to help mangoes to last longer while stored, we mixed it with avocado oil so it will became a little bit less britle
2:23 That's what she said. That's wrong I'm sorry, Great video.
I know you say no water but when that happens to me I boil the mold with the pour spout facing up and the wax melts and floats out.
You just have to make sure there’s absolutely no water around your molds when you pour resin.
I am glad you found the culprit! Haha can't wait for your next video man I really love your videos
Ah, the carnauba, very interesting! It's a good reminder to us to test new materials thoroughly. I just made a new batch of wax myself, and that's of course one of the ingredients. It's a really crazy wax, it's almost as hard as epoxy, and it has a considerable aroma, kind of like liquorice. But every good sculpting wax I've used has had it in there.
Misery and pain for you, but a teachable moment for the rest of us! Thank you for sharing your failures as well as successes!
To be safe use mold release agent.
They changed up the mater!
I loved the science!
I really love these fail vids and testing to fully understand what happened. My brain works the same way 😄 They're truly fascinating.
Once again I truly appreciate the learning process as opposed to acing like one knows it all.
One learns from mistakes and you are willing to show the process. Very much appreciated.
I had to check out your channel since I have had a few people claim in am your twin, 25 years younger. Apparently the hat and glasses is out Schick!
Hey Robert! Just stumbled upon this video and your channel, I've been enjoying your casting adventures quite a lot! I saw that you mentioned that this batch of "test waxes" were waxes you made yourself! I'm currently looking into this whole wax multiverse as my goal is to make wax for both modeling and casting lost wax jewelry models, are there any tips or tricks you would recommend for a rookie? Also, is there a video where you talk about these tests waxes? 👀👀👀👀 couldn't find it! Cheers from Argentina!
That was priceless... You remind me of my Uncle Frank.... Thanks
@RobertTolone bit off topic but for this video but do you have recipe for creating our own sculpting wax? I saw another video where you listed types of wax but how do I know what portion of each wax to add?
Thanks😊
Did you ever do/upload a video on making your wax/clay? Hard to think anything sticks to silicone...though i have older molds with signs of degradation. Small amounts of silicon oil might refurbish some of the original qualities of old silicon
Hey Robert, I have a question for you! I have to mold disks of paraffin wax, 89mm in diameter x 2-3mm thick. I run a slime business and the disks go on top of the slime for my customers to break up in the slime. The issue is that it's very difficult to get the wax to not stick to the silicone mold, and I can't use turpentine since this is something that people will be playing with. Any suggestions on what I can coat my mold with to release the wax without breaking it?
I know I'm looking at it like the Jarhead I am but Why Not Put it In The Fridge, Chill It, Then Beat It With A Hammer. If in doubt Blow it in place!?!! LOL ;)
Refrigerator was culprit on wax breaking. Let it cool naturally to avoid uneven shrinkage and crystallization that makes wax more brittle.
Well now you know how to glue silicone molds with wax!
😀 Yes! Handy skill.
Nice! Glad to see the resolution. Though it's not the case this time, this did have me thinking that 3D printed objects sometimes react with the silicone. I believe that generally prevents it from setting up. Do you have any experience with this?
3-D printing resin’s are notorious for causing cure inhibition. Every time I do a project that has been 3d printed I test my rubber with the resin.
Prime your print first.
You rock
Wow! My guess would have been some kind of residue from the miniature itself, but this has been very interesting!
i once used a cheap glass cup to mix my silicon (clever me: silicon shall peel right off and no more disposable cups in the trash!). The silicon residues got glued to the glass!! That is still also a mistery to me... maybe some glasses are actually porous even if they feel smooth??
Thank you for sharing this knowledge, I always learn something from you.
I'm really interested to see the continuation of sculpting this mini
Yup… just as I thought. Happened to me about 15 years ago. Your comment about diaper changes is hilarious.
Good video !
Thank you for sharing all the trials and tribulations !!! It helps in way's you don't even (but probably do;) know!!!
Not sure if it's been mentioned, or thought of, but Reaper's Bones minis are coated in a substance that will inhibit paint, and other stuff. Evidently, it didn't inhibit the Silicone, but maybe that remained in the mold, and reacted with the wax? But the second run didn't have the coating?
That was my original thought, since he said he'd used his usual wax, but I guess it wasn't his usual wax after all. :)
Thanks for the kudo Robert ! Keep up the amazing work you do.
Mould making and casting is still a mysterious dark art!
You cracked the code! Well done.
It’s better to be lucky than good.
I am confused. If you reused the wax that stuck the first time, why didn’t it stick the 2nd time?
Boiling the mould would've made the wax to melt and make the mould clean?
Newly subscribed. Been thinking I’d like to cast some of my 3d prints and this has been an awesome video. I’ll be watching the rest as well
Wax in the first (failed) casting looks shinier (different) to me.
You could have put the mold in boiling water to melt out the wax....
Im glad toy worked it out, and write on that bag of wax bits " don't use" :)
Yikes. Sticky and brittle plus soft and flexible, makes a hell of a glue.
hot water might have worked well to clean it. doesn't wax float on water?
Very nice vid very nice . Thank you caurnuba wax for the entertainment
That was super interesting to see. Lovely video!
Are you uploading next friday? Since it's christmas eve then.
Just in case: Have a merry christmas and a happy new year!
I shall put out something that resembles videos over the holidays - but lord only knows what.
@@RobertTolone How about a funny remix of all your fails und reactions to the fails.
Would sure be a lot of work thou finding all the pieces.
@@roger.agburn It would be a long video!
@@RobertTolone :D
recycled material wild card. good work detective.
This was great. I loved watching these difficulties even more than your common videos
Maybe there is plastic mixed with the bee wax 😊 maybe
Oh the joys of recycling... Glad to see such a great mystery solved
You can tell a dad who actually changed diapers!
I confess my wife did the heavy lifting but I am proud to say that I did my share. But only one kid so it wasn’t too bad!
You had a much bigger job on your hands!
@@RobertTolone - If it ended up in your hands, you need to improve your wet wipe technique.
Could you melt the wax in hot water instead?
I would have tried to clean the wax out of the mold in a pot of hot water.
This just happened to me today.
I was hoping to see a part 2 to this! Mystery solved!
Thank you, now I know what NOT to do when pouring wax :P
😀
Would you be able to clean it out with really hot water?
I don't cast anything with wax. So I have no experience using wax. I had assumed correctly that it had to be something that changed in the process. Interesting to see that it was one piece of Wax with different properties that caused such a mess. Soaking any mold in paint thinner will cause expansion of the mold. Literally if you put a mold in a jar cover it in paint thinner. You will get about a 10% expansion of the mold. Then the stuff takes forever evaporate out of the mold. Eventually the mold will go back to its original proportions but it never seems to be the same.
Yes, plus heating helps. But it will never regain it former glory. I know the feeling.
Just a hint… after cleaning the mold, a quick trip through the vacuum chamber will evaporate the residue super quick rather than overnight.
Never thought of that. I gotta try it!
I'm glad it got solved!
So am I. Would have been a really lame video if I couldn’t have found the problem.
At 2:37 it looks like there's a puddle of yellowish wax in the pie tin. Could it have somehow separated during the first reheat? It's similar enough to how the carnauba wax looked melted.
That was beeswax that was dripped in the pan.
Could you have boiled it out of the mold?
Very cool that you figured it out!
+1 for James Webb reference
dang carnauba wax!
😬
You can boil in hot water to take the wax off
I will give that method a try for sure!
Thank you for this. I am about to have my high school students try this. At what temp did you warm your mold too?
I heat it to the melting temp of whatever you’re filling the mold with. (more or less - I’m an artist, not a scientist)
Have too love mold making!
Saw a different video where they slice the mold straight in half hardly any zigzag and use zip ties with two pieces to hold it down.
Clearly they didn't know what they were doing!
Like I mentioned in the "Video 1" comments, why not use a mold release agent?
Because it has never been necessary. The wax has always released easily from the mold.
Glad to see the mystery solved!
The previous and failed attempt looked also a bit paler in color
Yes, the color of the sculpting wax varies quite a bit from batch to batch.
I wonder if freezing the mould would have made it easier to clean out?
Many people commented on cleaning out the mold with water. Many recommended boiling, the rest freezing! I think it is something that bears investigating.
Any suggestions for flexible silicon rubber that will work with pewter? The high temperature rubbers I have found are less flexible...or if there a flexibility metric that I should know? Thank you for all your work. I've been binge watching your channel. Have a great holiday season and a better 2022.
Thank you for showing your entire troubleshooting process! It's at least as educational as when everything goes smoothly.
If you want to clean it, boil it in hot water and the wax will float off the mould to the top?
A number of people have suggested that in the comments so I am inclined to try it!
interesting that one small change could cause so much confusion
This is the nature of mold making and resin casting. One small mistake at any step in the process can result in failure. That is why being systematic and consistent is very important for a mold maker.
Inspector Tolone solves the problem!
Ha, luck smiles down on everyone once in a while.
I appreciated that you went out of your way to make another video explains the faults and flaws instead of just cutting the time out and making another. Really makes non professionals be able to follow along as well.
Been waiting for this. Glad you have an idea as to what happened. Gotta admit, I enjoyed watching you make the mold, but I was really interested in seeing how you solved the mystery. Looking forward to seeing what you do with the wax figure. 😀
I’m curious why you chose to work with Tin cure silicone. Most other molde makers I’ve learned from or talked to use platinum
Tin cure is cheaper and much more forgiving in terms of cure incompatibility with sculpting materials. The big advantage to platinum is that the rubber doesn’t degrade over time the way tin molds do. I am a prototype shop so I do not need to store my molds for long-term use. The only time I use platinum is when the casting material calls for it or when it must be a food-grade mold.
@@RobertTolone hey thanks for the reply! Love your videos, and learning from your years of expertise!
You think maybe you’ll do a video on casting with urethane rubber or other thicker mediums with the challenges that come up?

I'm really stoked you figured this out. :) Love your videos.
