- Here is a quick and cheap way to save money on your molds for clear resin sculptures. Recipe below
4 ounces plain unflavored gelatin
12 ounces glycerine (1 1/4 cup)
1/2 cup cold water
1 1/2 cup HOT water
Watch video on how to mix.
Between this, and your homemade pressure pot video you’re making this hobby so much more affordable. I can’t thank you enough for your expertise!!
This is amazing! Thank you so much!
For anyone else interested... metric
-114 grams Gelatine
-340 grams Vegetable Glycerine
Random factoid
Vegetable Glycerine can be used as a laxative hence why it is sold at a chemist/pharmacy. It is also a popular ingredient for e-cigarettes/vapes. Not to be confused for Propylene Glycerine which can also be used in vapes. So huge thanks for confirming which one- VG, not PG :)
Recommend buying Vegetable Glycerine online from vape suppliers as it is much cheaper than chemist. (I'm a vaper myself and buy from Basedrop in Australia for about 10 bucks a litre. Chemist is about 20 for 100mls so )
Can't wait to try this! Be using Gelatine sheets not powder (cheaper but better quality) so will see how it works. Will share results.
Made it!
Halved and quarter'ed recipe.
If using different forms of gelatin, like gelatin sheets for example... make sure the first half cup of cold water is actually hot and mix that with the VG. It will cool down when mixed. Then add to pre-cut sheets.
Also if you have a digital thermometer, after adding all ingredients and if not dissolving, you can add to the stove in a cook pot and gently- VERY gently, mix it between 60° to 65° degrees. Taking it off the heat and placing it back on to keep it in that "sweet" spot. Most of the gelatin should dissolve no matter what brand or type you use.
And this may seem like a silly, common thing everyone might already know but hey, good to try crazy stupid things anyway... don't use blender or even coffee whisk (battery powered one).
It went from a beautiful, transparent mix to a opaque white mess of bubbles! Despite mixing all the gelatin.
@@shoshannaesam6067 Thanks for sharing your experiment results! I too, would like to use gelatin sheets instead of powder since I have the former and not the latter. Your explanation and tips were helpful!
@@shoshannaesam6067 Just note it's A-OKAY if it comes out that white foam like. Just let it set in the fridge per normal until it 'solidifies' than microwave it and let it sit out at room temp for an hour. It does solidify back down to a clear solid though may still look like a foam topped beer. Just cut off the foam part and microwave the foam again. It's a few extra steps but it does still work!
Thank you for sharing your great tip 🇦🇺😎
I finally got around to making some last weekend and while I followed the recipe to the letter, I was a bit worried at first. When I mixed it, there were zero chunks to strain out and the color was an even lighter and more translucent color than any batch I'd ever seen in other peoples' videos. Thankfully, none of that mattered because it solidified nicely in the fridge. I tried it out with two different figures (a little 2" Mirage from Transformers and a 4" Solaire from Dark Souls) and it worked great! Thanks!
hey guys, ive just made some of this and it's great. I just wanted to comment and let people know that this stuff doesn't react like regular silicone and sets perfectly when you use it on 3d prints this is an absolute game-changer for me thank you so much
The curing issue with 3D prints and silicone comes from the sulfur that 3D printing resin uses in its mix. Sulfur has a bad reaction with titanium based silicones and thus you get the issue with curing.
Glycerin is used to make soap. It is also an emolient. I use it to mix my own vape juice. PS, use a whisk to stir this mixture to avoid the lumps
This video is amazing and the mold compound is great. Silicone is super expensive and this works just as well if you’re looking for a much cheaper alternative if you’re willing to put in the work.
Hi! I'm a baker, and my husband and I are just getting in to 3d printing and resin casting. Based on my baking experience, I'm thinking you would avoid lumps altogether if you stirred the gelatin with the cold water first (without the glycerin), allowed the gelatin to completely hydrate, and then added the glycerin with the hot water. I don't think that change would mess with the integrity of the compound...
I did it this way and here were my results. The amount of cold water used wasn't enough to fully hydrate the gelatin and by the time I went to add the glycerin in the gelatin had solidified into a weird chunk and it was hard to incorporate. I ended up using a hand mixer on high with a towel over the bowl cuz it was messy and got the gelatin broken down enough but it almost looked curdled! I thought it might be ruined but when I added the boiling water in it all came together and I didn't have a single chunk to strain out!! It was pretty frothy so I did skim some off the top though I'm sure if you were it would go away. Not sure I'd recommend this method but the end result was very good.
I hope this is helpful to somebody!
I'm so happy to see this recipe for molds! This is awesome and I can have my daughter help make the mold because everything is non-toxic. Thank you!!
This is so cool! I was going to put off making my old molds because silicone is expensive, but at this price, I can give it a go now!
Thank you so much this will save me lots of change making molds for my resin models thanks for sharing
First, thank you for the clarification on the gelatin envelopes vs boxes. I really wish more people would remember that when talking about unflavored gelatin. Second, have you ever tried using a whisk to mix this up? I'm just wondering if that would help with the lumps a bit more. I'll certainly be trying this out soon. Really appreciate you sharing your tips and tricks! (Also, glycerine is typically used to to help dry skin, so if you did mix it with your hands, they'd probably be very soft when you were done!)
I usually do use a whisk to mix. Unfortunately I was just too lazy to get it. lol...
@@jennercustomtoys What I find works best is a hand mixer. You get little to no lumps (and thus less waste) however doing this makes it come out very foam/sponge like at first but letting it set per normal than microwaving it and letting it set again lets it solidify properly though this may need to be done two or three times, as it likes to leave a foam top almost like a beer so just cutting off the foam and re-microwaving said foam turns it back into a proper liquid fix's it right up.
I do wonder anyway to toughen this stuff up? It does like to rip really easy and I find even casting an item inside pulling it out more often than not rips this stuff up. So any idea how to make it a bit thicker or stronger?
Thank you for sharing your knowledge!! I am so excited to try this and your pressure pot!! I love this option way more!!
Thanks so much for this vid I’ve been watching the series very helpful thanks so much !!
Awesome video ! Thanks Bruce!!
I have made this as a test mold myself it did work great, I made a half batch instead it didn't have any lumps
It's funny, the only time I had lumps that bad is when I made the video. Lol.. figures.
@@jennercustomtoys well I am indeed please with the results of it made another batch of it already but testing with craft glycerin I'll be attempting a new mold soon
You don't need to add 1/2 cup cold water. I mixed the glycerin and jello together first, then 2 cups of boiling water. No clumps and turned out perfectly.
Thanks for the tips!
Thank you so much for sharing your home receipt here. Can’t wait to try as I did one months ago just using gliserine and sugar but it did not work out very firm. 🌼
I wish I knew about this when I was in school! Felt like Smooth-On took most of my paychecks sometimes
It definitely helps the cost.
Well, you’re my hero
When I make jello, you add the hot water first, this dissolves all the gelatin. Once all the gelatin is dissolved , then you add the cold water. I’m not sure if this will screw up the process. It’s worth a try.
This is ingenious!
Saves a lot of money in the long run too.
👌
I just ordered the supplies and resin, so excited to try this out as my first foray into resin casting. I love the idea that if I flub up (if? hahaha) I can just remelt and try again. I aim to make my own D&D dice. This is the first I heard of using gelatin for mold use. Thank you for opening up my eyes and sharing your knowledge. I wonder if agar agar would work... (a seaweed vegan alternative to gelatin) it is pretty clear and you use much less vs the powder gelatin... That is for a future experiment after I get proficient at using your recipe. Thanks again! Have a good one!!
Please, do share your experiments
Hello friend, do you have any progress with your reusable dice moulds? I would like to foray into that as well, and would love to see if this is a solution for this type of moulds.
Thanks for a great video! I can't wait to try this!
Dude, kickstart this... You've accidently won a 1.88 billion dollar industry. (っ◔◡◔)っ ♥ ░ ♥
I've seen recipes on TH-cam for homemade molding material by mixing silicon latex with cornstarch (and naptha or mineral spirits for a pourable version). The mold itself is re-usable to make multiple copies of a Master, but unlike your great idea, I'm not sure the resulting latex mix mold material can be re-heated and re-used for another Master. If anybody knows, please add a comment. Great video and idea. THANKS.
Ha! I have that exact same shirt!
I just made this today and I mixed the glycerine and gelatine before adding any of the water and got no lumps at all in my mixture.
When I did the video I got a lot more lumps than I usually get... But it worked out fine. Good luck to you. And thanks!
You can also pick up gelatine from bulk stores for pretty cheap. Even cheaper if you tag it as oat bran 😉
I found if you mix the gelatin & glycerin together first, then add the cold water & mix. Once mixed well then add the hot water. No clumps that way. Just thought I'd throw that in. 😉
Usually I don't have lumps like that. But of course because I was recording that time it came out funky. But it still worked just fine.
@@jennercustomtoys Lol. Seems nothing ever comes out like it should when you're trying to explain how to do something crafty. I know from experience. I work better without talking & just doing. In your case you are doing a tutorial so you have to do both. Glad to know it worked out well.
This is awesome!
I sometimes use glycerine to tan snakeskins
Sounds interesting. I've never done something like that.
Thank you for your detailed transfer of knowledge. Can you please state the melting point of the gelatin mould. Will it melt in hot weather? Can I use it for making lithioum battery adapter or power tool socket moulds?
Also in your description you are referring to a pressure pot. Is it pressure or vacuum pot? If its vacuum air bubbles are going to the surface immediately and hence there is no need for overnight pressure.
Great video. I'm always experimenting with new ways to make molds. Do you think this would work for concrete? Even if it was destroyed it would be awesome. If anyone has tried it with concrete let me know please.
I really don't know man.. I wish I did.. I don't do very large castings. My first instinct would be to tell you no.. but who knows. If you give it a try, let me know. Im curious now.
I mixed the jello and glycerin together before I added 1/2 cup of cool water, and had no "buggers" at all. Now I'm wondering if I should not bother with 1/2 cup of cool water, and just go straight 2 cups of hot water. Maybe next batch. 🤷♀️
I been trying to cast my 3d printed DnD minis. I tried playdough and hot glue but it looked jank as hell. I wanna try this and maybe using sugar resin to see how that works.
What about stirring with the small battery operated stewer?
I'm sure that would work. But the whole point of my videos is to do it the most economical way. I'm cheap. lol..
Hello! Love the video! Do you know how to make it stiff like resin? Many thanks!
I'm sorry, but I do not understand your question...
Thank you so much for this video , just made my first batch following you vid and all came out perfectly. Just one question where do you store it? does it need to stay in the fridge if you don't use it ?
That's one of the good things about it.. you can refrigerate it if you want but I keep mine in a covered plastic container sitting on my workshop bench. Never had a problem with it.
@@jennercustomtoys awesome thank you again for the video and the quick reply much appreciated
if you dissolve the gelatine in a little of the hot water before you mix in the glycerine and the rest of the water you will have fewer lumps
Can I use normal glycerine instead of the vegetable one??
What if...you added the gelatin to the water, then added the glycerin? to dissolve the gelatin better and avoid lumps?
I added the jello and glycerin together, then added 1/2 cup cool water. Stirred it for a few minutes, then added the hot water. No clumps at all.
Thank you for sharing. This is awesome. I have a couple questions which I hope you can answer. 1- I know you mentioned this is for clear resin, my question is could we color clear resin with micas or paint prior to molding? 2- do you think this mold could be used for other media’s like plaster of Paris or clay as well? Thanks in advance. Hope to hear back from you.
I use mica powder with no problem I'm the clear resin. I've never tried player or clay. Let me know if you try it. I do know any casting material that heats up doesn't work well in the reusable compound.
glycerin is also used in vape juice. ie E-juice or E-liquid
Would it work if heated on the stove or oven instead of a microwave? Don’t have a microwave 😅
Good question.... I don't know but I'm guessing it should. Let us know if you try.
@@jennercustomtoys I’ll have a go at it soon. I’ll post a comment whether it is a success or a failure 😅. Thanks for the informative video!
I've made this following along with you and your recipe. Not sure if I did something wrong in the actual mxing or anything, but mine no matter what keeps ending up with a white foaming beer head when cured. Anytime I melt it down to pour a mold, it looks clear pours normal, bit as it's cooling starts to form a foamy white beer head. Not sure if I did something wrong along the way. I made mine right along with watching your video and I measured everything out exactly the same. It does make a mold and will cast things just fine, just it has a foam head on the top exposed area once cooled down. Did I overmix perhaps introduce too much air in the batch? I did notice when I very first made the batch it looked more milky and frothy after sitting in the fridge. Once I did the first melt down, it turned clear amber. Just now it always has a head of foam on it. I did use Knoxx brand gelatin but I could only buy the glycerin from ebay which was a different brand than what you had. Not sure if maybe it had something it that didn't work quite with this.
I get a little of that foam sometimes also. It's never really hurt my mold though. I think it might be from over heating in the microwave. Let it cool a little before you pour it on your master when making a mold. See if that helps.
Also, never let the stuff boil.
I made some and it has a sticky residue not much tho is that normal ?
Only for the first couple uses.
can i add a filler to it eg calcarbonate
So this process derives from applied makeup effects in theater/fillm as an alternative to latex. As a former chef, get some sorbitol and sub it for either part of the glycerine or water
If you are referring to Liquid Latex for makeup and also certain types of molding methods then no, not at all. It is a cheaper reusable substitute for silicone molds. If you used this as you would liquid latex then you would get burned. Also, sorbitol would not work. It would have a reaction with the resin poured into the mold I would think. It's not the same.
hey, thanks for posting this amazing video!
I was wondering whether this method was suitable for cap molds, or would the cap stick to the basis even if I coat everything in gelatine?
thanks in advance!
Honestly I don't know. Give it a try and let us know.
@@jennercustomtoys Thanks for the quick reply!
I've just finished the first mold and it seems to work perfectly fine as long as you use enough petroleum jelly / vaseline. I messed it up a little, but I believe that was actually my fault and not the material's as the cap layer peeled off perfectly fine in most places. Thanks a lot again for sharing your recipe, you've saved me about 30-40$ (Silicone is crazy expensive right now, at least in Europe) :)
Probably wouldn't have lumps if you bloom the gelatin before adding the glycerine
Why not use a mixer to get the lumps out
It makes too many tiny bubbles get in the mix that way.
Hey! I made us some of this recently and it's great! One quick question, the casts I get out of these molds goes slightly milky (more towards the bottom of the cast) Vs the same batch of resin used in other molds, any idea what I've done wrong?
I'm assuming you are using clear resin? It sounds like you are getting air trapped in the resin while mixing it. Possibly from over mixing? Try mixing it less or maybe invest in a pressure pot. You should see some improvement.
@@jennercustomtoys ok, I didn't think it would be caused by air as it seems to settle at the bottom of the mold, I will try with a bit less mixing.. I'd had a problem with under mixing before and was probably just over compensating! Thanks for the advice!
How much hot water, cold water and glycerin do I use with .5 ounce of unflavored gelatin? I ask because I only bought 1 box of gelatin and 1 bottle of glycerin and was trying to avoid going back to store for more. Plus I only need to create molds for stuff less an 1” x 1” x .25” in size.
I'm not sure
Are you using metric cups or US cups?
US measurements.
I had no lumps. Hope that's ok!
That's great! That's the way it's supposed to be.
Hi. Are u able to use this for food and fondant
I wouldn't, it tends to get dirty the more you use it.
Thanks so for replying 😊
Can this be used with concrete casting?
No. One of my viewers tried and it was an epic fail. This only works with clear resin so far
Can this be used to cast Ultracal 30? ( it's a gypsum/concrete/plaster paris type of compound)
I haven't tried that but my guess would be no.
I'm a year late but yes it can.
I imagine they aren't using the gelatin as a mold but as a makeup prosthetic.
How much does the mold shrink from the orginsl cast..does it shrink with time
I only use the mold once or twice then I re melt it. I haven't noticed any shrinking.
It does shrink with time, due to water evaporation out of it. But if you remelt frequently it shouldn't be an issue, and its more a matter of initial shrinking followed by stability
The problem is if it’s hot , it will destroy my casting which is made of silicon
You are correct, but this compound is only for clear reason specifically.
Why not use Brand Glycerine? $$$$
Because I'm cheap and that's all they had.. lol
What would Halen if you filed this with clear silicone calking?
I don't know... Give it a try and let us know.
In the recipe, it states that we require 12 oz of glycerine, or 1 1/4 c. It is actually 1 1/2 c of glycerine.
Glycerin is more viscous than water, therefore it weighs more. I use two 6 ounce bottles as that's how they're sold here where I live. When poured into a measuring cup it comes out at 1 1/4 cup.
@@jennercustomtoys ok, thanks a lot for that.
Can this be used for UV Resin molding?
As long as the resin doesn't heat when it cures I would think. Give it a try and let us know.
Does it work on polyethelene, polyurethane and polyester? Thanks!
I haven't tried those with it. What I can tell you is any resin that heats up probably won't work well.
I’m trying to use this method to make reusable dice molds but it keeps breaking when I take the dice out is there a way to make the mold material stronger?
Put it in the refrigerator after your casting cures. Or when you make a fresh mold put it in the refrigerator and it will get more rigid.
Also, the more you use the compound the better it works.
Cant you desolve the powder in the hot water then add the cool?
It seems to get less lumps when you saturate it with the cold water first.
@@jennercustomtoys ok I am going to try it out this next week. Thank you
Anyone try casting wax in this recipe? I made it and I was able to cast wax in it. The interesting thing is that although the wax is Molten it cools rather quick and also I put the mold in the freezer LOL
Great idea... I tried once and it melted the mold. However freezing it is a great idea.
@@jennercustomtoys I made the mold first then I froze it then I poured the hot wax in and put it back in the freezer immediately. As far as melting the mold it’s smoothed out some details but it didn’t melt out the structure too much
Has anyone every messed with this molding compound and made a casting of a hand
Thinking if I let sit for a bit to cool some wondering if I can then add my hand and sit for a few hours
No way. You would burn yourself.
