DIY FOOD SAFE MOLD. Freezer Mold. Gelatine and Glycerin

DIY quick mold for casting. Takes only a few minutes to mix, sets in about 20 minutes at room temperature. Sets in the freezer in minutes.
MIX:
7 gr. Unflavored Gelatine
40 gr. Glycerin
stir until incorporated.
Add:
40 gr. water

You make THE BEST casting videos, available anywhere. Thanks so much!

[@GEOsustainable]

I am so glad you like my videos. Your comment is inspiring. Thank you.

[@candicedewaal]

I love using these ingredients for moulding. There is just one component that I add to hide the STRONG smell when its hot...and so I add vanilla essence.

[@GEOsustainable]

I love that ! Thanks for sharing.

Hello, love the video! Do you know how to make it hard like acrylic? Do you know how to make bioresin? Many thanks!

[@GEOsustainable]

No, sorry. I don't work in either of those medium. I am glad you enjoyed. I do work in other medium if you want to give a look.

[@markmikhail4279]

How is your final product coming out so clear and transparent without that typical yellow tint you find on other recipes? What’s causing it to come out so clear? Amazing!

[@GEOsustainable]

Thank you. Follow the directions and use the Knox.

[@DOJ77]

Thank you for sharing. Do you think I could to use Agar Agar instead of the gelatin?

[@GEOsustainable]

Yes, many folks do. I would guess you are making 'cold process soaps'?

[@joshuagutierrez5491]

Would this work for resin?

[@leadslinger5130]

I have a question does glycerin preserve the gelatin for a long duration? And second does it change the property of the gelatin? I'm looking for a preservative for my ballistic gel so it can be stored unrefrigerated. Any thoughts would be appreciated thanks.

[@GEOsustainable]

You know this is going to end with...try it, and let us know. Glycerin is a humectant (holds water), used in so many applications, including those soft bake cookies. The same is true for gelatin, glycerin softens it and makes it flexible. Glycerin will in time, work out, but that takes years. I buy it by the gallon for my bioplastics (protein and starch backbone polymers). Glycerin has no bactericidal efficacy, and can even promote bacterial growth if not used with alcohol, as I used in the WHO formula video I posted. I suggest that you search for alternative humectants if you plan to not refrigerate your ballistic gel for more than 3 hours. One trick I use to retard bacteria is Thymol (thyme herb) and is what is in Listerine to kill bacteria. Hope this helps, if not, email me and we can hammer on this together.

[@celeeveland2636]

Have you tried making cement pots??

[@GEOsustainable]

I have not, but this method should work well enough. I do work with plaster and this works great for it.

[@ariftasyurek21]

Hi I wonder how hard I can make this material. this is very important to me, I would appreciate it if you help

Well, then, let's discuss your requirements via email. Replies to a reply don't get a notification. My email is posted in the description.

[@ferretface8782]

Can this be used to make a mold of your teeth like with dental trays filled with alginate... or will the heat of your mouth not allow it to harden?

[@GEOsustainable]

try it and see. let us know.

[@whowhy9108]

Hi, does the glycerine need to be 100% pure? I see some are sold as 99.5% which are cheaper and wonder if one could get away with that one. Thx

[@GEOsustainable]

Yes, 99.5% is fine. That is what I use. I use Glycerine made for live stock (cow and horse).

[@whowhy9108]

@@GEOsustainable oh great :) thx. I'm purchasing now :)

[@unicornsdoesexist]

I have another question lol, do the molds ever go to waste? In how long? Thanks

[@GEOsustainable]

I can't say, I have never really used these much.

[@Gawron..]

I am looking for a negative for casting. I want the mass to be completely non-toxic (fumes) - preferably edible :) And it would be good to be reusable.Until I found this movie. I plan to make a figure from plasticine / clay Monster Clay type. I will probably make such a wax plasticine myself, because there are recipes for it. If I am not satisfied with the effect, I will buy Degas (cheaper version of plasticine than Monster Clay). The casting, on the other hand, will be plaster at the end. Could it be any gelatin?. Apparently Agar Agar binds more strongly than gelatin. Did you check it?

[@GEOsustainable]

I did not check it. I bought some, but the Gelatine was handy. Agar has a higher melt temperature, but everything else should be the same. Depending on your application, the mold should be reusable. Even if not, you can use this over and over again for your negatives.

[@Gawron..]

@@GEOsustainable The tensile strength should be the same?

[@helensarkisian7491]

I’m wondering why I would want a sticky mold. Or is the point that, unlike the usual silicon molds, this material can be melted down and recast?

[@GEOsustainable]

It is a food safe mold that kids can have fun with. It can be remelted, yes. You can adjust the Glycerine to reduce the 'stickiness', or add cornstarch coating, lot's of options to to try. Enjoy experimenting!

[@whowhy9108]

Id say the stickiness of the mould is not what one is after, but considering this is primarily a cheaper alternative, stickiness can just be ignored :)

[@manalhassan4040]

What is an additive be added to gelatin to dissolve in cold water?

[@GEOsustainable]

You must be joking, it melts at 100F

[@manalhassan4040]

So it can be add to a material as catalyst

[@ruyvieira104]

Can you pour that into silicone molds to make edible things?

[@GEOsustainable]

Sounds like a fun idea.

[@markmikhail4279]

Your measurements are all over the place, in grams, ml, and mm. Which one is it for all ingredients:)?

[@GEOsustainable]

yep, measurements will be given in different standards. You can convert as needed.

[@NikkiNapalang]

would this harden or does stay jelly-like?

[@GEOsustainable]

It depends on the thickness, and the hardness you want. The factors that will be variable are the thickness and the amount of Glycerin. For hardness, I demonstrate a food packaging version here: kzbin.info/www/bejne/bIixeaKBmquEi7c

[@NikkiNapalang]

thank you!!! I also gotta ask, if i make a thick one, would it shrink and crack as it dries? I used cornstarch instead of gelatine based from another recipe and it keeps cracking. ☹️

[@ruyvieira104]

@@GEOsustainable so if you want it to be jello-like but still don't break apart, what do you do? add more glycerin and water?

how could you incorporate this method into making a fishing lure? that's a bio plastic or something close

[@imissnickplur4964]

i was thinking toy gummie bears ...i'd like to use them as inclusions for slimes. people are using resin pieces to add as a topper to your slime creation, & they use foam & clay pieces, i want to make little squishy pieces that way they're soft & pliable or bendable like the slimes as you mash & squeeze them. plus if you're into slimes then you're probably also into squishies. the squishy toys are harder & expensive to DIY, unlike the slimes, and so its thrilling to handmake squishies, especially the clear ones.
