Thanks for sharing! I've used the same recipe to make prosthetic pieces for Halloween makeup, lifecasting, etc. Much cheaper than alginate or silicone and totally reusable.
Hi , you have used this recipe for lifecasting? I am thinking of doing the same but i have a few conserns about the temperature and "stickiness" of the material , did you have to make a two part mold or was it possible to just wiggle the body part out? What material did you use to fill the molds after? I was thinking about plaster of paris but i have read it doesnt work very well... And aproximatly how much time did it take for the mold to cure? Thank you!
@@AS0144 You have to be careful about the temperature so you don’t burn your subject, of course. I let the mixture cool enough to not burn the skin and then quickly apply it. You will probably need to work a small area at a time since it cools and solidifies rapidly. I then backed the mold with plaster cloth and allowed it to harden to help support the mold. It was a simple one piece mold that the subject was able to wiggle out of. More complex shapes may require a 2 part mold. I used plaster to fill the mold. I used silicone oil as a barrier in the mold to keep the plaster from sticking to it. I would also recommend using silicone oil or petroleum jelly (very light coat) on your subject to make the mold easier to remove from your subject. Either way, it will take some trial and error to figure out what will work best for you when using this material. Be safe!
I heated the water to 120 degrees F before adding the gelatin. The gelatin completely dissolved after a few minutes of stirring after which the glycerin was added. I poured the mixture into the form just as soon as the glycerin dissolved.
I made a mold using your method , however the clear epoxy resin turned white and did not come out as glossy and shiny as the mold. The resin had reacted with the mixture. But thank you.
second report back, increasing the gelatin to glycerine to 1:1 works well, however, I face another issue, trying to make a two parts molds and they got stuck together bad... have seriously put mold release on it
Great Idea just made a small batch but the stirring while on gentle heat created a lot of bubbles which stayed once cured, is there a way to get rid of these before pouring over object
They can be removed with a spoon or other implement. Also, try a small amount of IsoPropyl alcohol. If you read the comments there are several good ideas. I have cast many items and the bubbles have not caused a problem. Thanks, Ken.
i think you mentioned it before, may I ask again, is it food safe that is can i cast food into it?? and also would resin be too hot for this mold?? many thanks
@@observationsblogcom hi Ken :) I tried making this mould with one of my mini sculptures (tested it twice) both times the mould looked great, until i tried to open it, which is when it just sort of crumbled. Not sure what I'm doing wrong? I'm using vegetable glycerine and colourless gelatine. Followed the instructions. Any feedback, much appreciated 👍
@@observationsblogcom thx. i did follow the exact measurements, might add more water next time. Everything looked pretty good, consistency, the way it set, except for crumbling at the end when i tried to take out the sculpture.
Help! Any ideas why a part cast in plaster would come out of the mold oblong? The pattern was round, about an 1 1/4" diameter and 1 1/2" long. The mold material worked beautifully, just produced an out-of round part. Kind of ruined the day. Any help will be appreciated. Thank you.
I'm currently overseas and its proving difficult to find pure glycerine. I have been however reading about plausible glycerine substitutes i.e. light corn syrup, vegetable oils ect. I know those can be used for fondant and royal icing. I'm just curious if any of the mentioned substitutes would be suitable for your recipe? Great video and much appreciated.
Any plasticizer has to be water soluble so that leaves out the oils but light corn syrup may work. Try a small batch and test but it would be guesswork on my part to say that it will perform like glycerine, Ken.
Agar is not a good choice and if you go to my open source website, observations.com, "In the write up"you will see a candle that I made using a cold mold and somewhat cool wax. Thanks for the question. Ken.
good one. i cannot find video 2, however i saw it on your site you mentioned, but there is no subtitle. can you please send me a link of youtube video 2 with subtitle.
Yes, but they both contain water and that can alter the mold so it is a tricky process. Refrigerate the mold and hope that the POP won't be too warm for the mold. I had pretty poor results, Ken.
This material will lose water over time so sealing in a plastic bag and refrigerating will help. I have had some for at least two years. The only similarity with silicone is in flexibility. But, it will never equal real silicone. Ken.
can we use this material.to make a special.effect sfx like a crown melted on a head for example? does this stick on the face? and can be stick to it? im thinking of it for sfx makeup ? does it work ?
@@observationsblogcom i am taking a course at uni sfx or special effect makeup. we r asjed to create a character from a play and apply speciall effect make up on it and present it into stage. i chose the play exit the king so i am working on the king character who is attached to his crown and refusing to resign. so i am working on making the crown as if it is melted on his head. that s is my idea i am searching of how to make a crown look like as it is melted on so someones head. i donno if i can express myself better now. i hope u can understand me
Thanks as the explanation helps. It should work but I would reduce the water and glycerin by 20% to make it more stiff and easier to work with. Hope that this helps, Ken.
@@observationsblogcom thank you for your quick reply. i highly appreciate. i Will try it and will take ur advice into consideration. thk u for ur time. all the best
I need some help. I am trying this recipe and it's not working right. I think the problem is that when I mix the gelatin and the water, it's not blooming, or whatever it is called. Im 95% sure I have the correct measurements and the gelatin I just got from the store.
Hi Daniele, The unflavored gelatin is added to room temperature water with stirring and left to sit for 3 to 5 minutes to bloom, (swell and pick up water). Then add the glycerin and heat to dissolve but don't boil. Shouldn't take more than 5 minutes to dissolve. I've never seen it fail so hope that this helps, Ken.
Thank you. For whatever reason when I add the gelatin and the water, stir it, and leave it to sit, it does not bloom. Perhaps I got bad gelatin, I'm not sure
Yes, with some conditions. First, all resins are exothermic (give off heat) and they are somewhat different. In most cases the best way is to chill the mold and I would recommend trying a small sample with the resin that you use. Ken.
Yes but the mix has to be cool enough to be comfortable to the skin. It will take longer to cure than alginates or other methods but you can use cold water to cool more quickly. It is not the best way to do life casting but it will work. Try a finger in a small test. Good luck., Ken.
Probably not as the water from the concrete will degrade the water soluble mold. Concrete as it sets is also exothermic and will also cause cause problems. Sorry but that is the situation. Ken.
For how long the gelatin gotta go into the fridge? I tried this formula but it was hard to get the figure out of the cup also the gelatin break as soon it was out... Please help
My best thought is that something is wrong in your formula as it really does not need to be refrigerated and should not tear easily. Please check the amounts of gelatin and glycerol and the cooking process. Thanks, Ken.

crayons melt at 120-147 degrees F, will this tolerate that temperature range? I have grandsons... they're still young enough to be impressed with me!
never mind, might not hold up if this melts at 130 (per the video).
It can work if you chill the mold and let the melted crayon cool until just pourable. Good luck, Ken.
Can resin be used in the mold?
Yes, but curing resin is generally exothermic so chill the mold first. Ken
Yes it can but I usually freeze the mold for about an hour before I fill it with resin it helps to stop the heat from melting the mold
Wow
If you add epoxy or melted chocolate doesn't the heat from them degrade the mold inner details at all?
Yes, and that is why I recommend chilling before adding exothermic materials.

No, but it can be if you use food grade glycerin. Great question, Ken.
Can a dental impression be made with this?
No, since it is water soluble it will be distorted by the water in the mouth and the glycerine is not food safe unless it is vegan. Ken.
