Silicone Mold Making & Casting

[@mayrakopjansen2814]

This really is the most clear tutorial I’ve seen up till now.Thanks for sharing 👍👍👍❤️

[@ray040572]

I did a stone brick mold and came out nice! Thanks to your video.

[@snygaard777]

This is very cheap and economical. In the past year Iv work on some million dollar houses and needed to make some casts. One job i had to make a 200 mm by 500 mm corbel. The tube silicone rubber cost me 70$ for roughly 6.5 litres.!!!! To buy that in moulding silicone would have been 300$ plus!!!! The draw backs maybe the terrible vinegar smell which can also strip paint to. But haven't had a real problem yet. Thanks so much works a treat.

[@june7422]

Some people in the comments are just straight up smart arses. The process works guys. Thats all she’s tryna show. No one asked for your University detailed explanations.

[@lespaulthomson3167]

Looks like a motel jacuzzi

[@dannersmyers]

If you do it in multiple stages like this it is likely that the silicone mould will break apart where the different batches meet

[@jerrywhidby5259]

Danny M True, I did two batches right behind each other, and you can see a parting line. I was able to separate it a little, but did not try to. pull it apart completely.

[@Chafalota]

This is my experience when making the silicone caulk molds: When you are kneeding the silicone in the dish soap it traps air in it and in that air it traps water with soap that you are working with. Now the problem I had was that the mold made a cured skin on it but on the inside it was still not cured and it never cured because it had bubbles with soap and water traped in it. I found this out because I cut one mold with scissors and there was water coming out of the silicone.

[@bigsouth779]

+WILD CHILD Did the water ever cure out of your molds? I was wondering about this myself because I'd like to make some candle molds.

[@Chafalota]

No it didn't. After 3 weeks, Then I tore it up to see inside of the silicone and it had bubbles full of water. So The idea was good but the product itself is not designed for making molds. It would have been great to make them out of silicone calk because the mold kits are so expensive. I guess if you want to make a temporary mold it would work but then after a couple of weeks you would have to throw it out.

[@bigsouth779]

Well that sucks doesn't it?

[@Chafalota]

YES IT DOES !!! :0(

[@carolynspade7564]

+WILD CHILD did you need the silicone outside of the soapy water once it has started ti set??? that should have worked the air bubbles and soapy water out of the silicone

[@stevieandthebarbies]

Thanks for a great video - I seem to keep finding American kids making very expensive moods by mixing the silicone with cornstarch (called cornflour in UK), baby oil and acrylic paint (though I can't see the point of colouring a mold). I'm going to be making very small moods for doll shoes and this simple version seems perfect. The one thing I missed (maybe lost in the background noise) is how long to cure the silicone before removing from the original - does the silicone need to cure for the full 24 hours (as if it was being used as a waterproof sealant)?

[@kgs42]

Teacher sounds very good !!!

[@sandrastewart9438]

Hi could you please give me the name of the silicone you are using. Thanks for the great video. Kind regards Sandra

[@neil1261]

I can't believe I've been fannying around painting layer upon layer of latex on my molds when there's this method Thanks

[@magnuswootton6181]

i dont know they put it in the water first, may as well go straight in the mould. u do layer by layer for latex because it dries quicker.

[@jasonborne5359]

So, im searching for a way to make a part out of silicone. What i need is essentially a toe spacer for bunions that i can wear in my shoes. I have many ive bought on amazon but none are wide enough. If i use this teqnique and form it in my foot the shape i need it then let it dry.. how stretchy is it? It needs to be very elastic as to be comfortable wearing all day

[@manoloblasco473]

to protect it in the future use plenty of talc , after dry it very well ...

[@slagundogan8361]

thank you for this video. can i use this mold for plaster of paris projects?

[@jerrywhidby5259]

sıla Gundogan I did, but I spray a release agent on it first. Not sure if it was needed.

[@Anzho]

Do you have a video of the finished product? Also does this shrink too much?

[@snoopu2601]

You can make something 3D you just put it in the middle of the ball when it dries the next day just to be safe when you cut your product out you don't want to cut a straight line try to cut a zig zag down one side to pop your product out. I've made a mold when we were bronze casting. I pour the cilaca wax into the mold to make many of one thing. Then keep dipping in the cilaca casting mix it took about a week the whole process it can be expensive because you have to leave the fan on for a week. Then we put the casting in a ceramic making oven the cast is ready to pour we bury the cast in sand then pour the multing bronze in the cast wait until it cools the brake the casting off the bronze it will capture every little detail even your finger prints if you leave them on the wax mold. I for got a few steps like the wax vents you have to attach to your mold so the air can escape you just cut them off with a saw or wire snippers depend on how thick the wax vents are .

[@hena5756]

I have a question,if leave the silicone in the water ,when it will get harden ? I appreciate you

[@lynettemckone918]

Why didn't you cut the nozzle off? It would make it much easier to dispense into the water :) thanks for sharing.

[@southjerseysound7340]

+Lynette McKone because you need the spaghetti like texture to help expose the surface to the cold water as much as possible to help start it setting up.

[@abigailrae1365]

No you don't. It's a much faster process when you CUT THE TUBE to release more of the silicone at once. 1. Easier to get out of tube. 2. Faster to get out of tube. 3. Same time spent Mixing in hands, (and actually even quicker since your working with "more" silicone). 4. Larger amounts of silicone in hand ='s bigger balls, ='s Less time spent Pumping the tube, applying the silicone to your project, and going back to repeat all the steps, over and over again. *Cut tube to the Bigger Section to release MORE Silicone at one time!*

[@nigeldonaldson1647]

Will this work with fibre glass resin, can you tell me if you know?

[@TheMiiiyyykkk]

Very helpful video,does the silicone stick to the plaster mold ?

[@kaieteurcanada]

did I hear correctly... cold and wet sets the silicone?

[@sa7oooriak234]

Did you ise cold or hot water

[@manasespascual8603]

What did you mix with the water is it dish washing liquid

[@lifeonearth4139]

Why do you add washing liquid ? What is the action? How much to add& how long yo keep in the water?

[@diysuperguy4146]

You can tint the silicone with universal tints as well.

[@misstaja1976]

I wanted to see you finish it

[@werefox61]

2 questions. ! where did you say you buy it cheap? Can you add color to it and use it to sculpt with?

[@Hellsong89]

+Heidi Fox Home improvement/anything building related stores always has it, but getting it cheapest.. i think you could try search ebay or just give a call to importer, but be ready to buy lots in that case and i mean by the pallet loads. Adding color.. it comes in white, black, clear, but you can add paint to it, but it has to work with silicone. I'm guessing oil base paint could work? Using it as sculpting is no go. It flex way too much to be accurate and you really only can cut it. Using router tool or similar will just rip it. You could try to find suitable method, but no. Its cheaper and less trouble some, to make part from something like clay that you can sculpt and then use silicone only as mold. Also when your pouring silicone into water, take the tip off, so you trap less water into putty. Making strings like that just wastes silicone and makes it harder to handle. You really only need soap+water mix to prevent it sticking in your hands, bucket and to work peace. Actually you could try coating work peace with soap and then pouring in the silicone directly on the work peace, then spread it with soupy hands or some tool.

[@pensychan]

Awww man, I wanted to see the result!

[@edkasper4758]

What was that you squirted into the water? You mention Cold Water How Cold ?

[@user-cg9oi5ug4d]

quick tip unscrew the nozzle and pump it faster

[@timeakovacs658]

Hot or cold water?

[@prototype9000]

silicon and silicone are 2 completely different things you are not putting silicon into the water

[@na7340]

You said you can use it for chocolate, is this silicone food grade? And is it safe to use to produce food product?

[@vibhupande]

why don't they use a soaped-up sphagetti strainer or even a sieve to collect the strands ? seems easier than the hands method.

[@maximmortal3170]

Is the blue liquid a secret!!??

[@pudsnpies]

Thank you for this. I tried it today and it worked well. No mess. Jon

[@williambarnes7642]

I like your video. I am wondering why you put the silicone in the water first. Why couldn't you apply your soapy water to the piece and then use the silicone directly from the tube?

[@kevinkenny8739]

Thanks so much for posting, this will save me a lot of money, plus they sell it every where.

[@lambo1diablo1]

Doesn't this mold shrink this way? I made molds using universal silicone + corn powder + baby oil and the molds shrink.

[@SHER7067]

I REALLY WANTED TO SEE THE END PRODUCT!!!! Can you do a follow up video please!!?

[@francoiseveronstamp]

you mention molding chocolate in this silicone. Does it mean it is food safe??

[@TheWiseMagpie1]

No...it is NOT food safe!

[@williamdevine2858]

can you use it on plastic

[@fm00078]

WHERE'S PART 2? .. .. .. "Removing the finished product."

[@JO-ly3hi]

Why not cut the end off the tube and shoot the whole log into the water in one piece?

[@detha123456789]

How long does it take to set usually?

[@robslaphead]

hi I was wondering if u could help me, when I tried this which worked wonders, but it smells like viniger is that normal? or can I add something to it to take away the smell? thanks

[@angelallarena1259]

Y que paso después? Que salio de eso?? Hablo Español!!😞😞

[@ThePerla2000]

thank you so much this is going to help me so much with my project in anatomy class

[@p.d.catito3313]

pour silicone into cold or hot water?

[@maryreynoldsreynolds8627]

How do you get rid of the smell, after you make them .

[@AT-Legence]

its may inexpenfive, but it works also like crap.... just buy proper silicon mold an resin, they getting cheaper and easier to hald every year. like i used to take platsil 73-20, it has a working time of 5 mins and cures less than 2hour fully out and you can go casting right away. its a 50:50 part A:B mix, so verry easy to mix! i remember 1kg is about 50 bugs or so. im sure 5 silicon tubes are almost the same

[@snygaard777]

Your figures are way off!!! This is by far the best and cheapest way of making a cast.

[@alokkumaracharjee]

Please say me, what this type silocon?

[@ladystephokoro9314]

What if u want to make a colored mold

[@mahdikashefi4817]

بسیار آموزنده و مفید برای بیننده با تشکر از شما

[@jershaus]

Why not apply it to thw piece? Inatead of water?

[@richardsmith7783]

To make fishing lures from that how long dose it take for the Silicon to set up?

[@creatixstudios8889]

Does it dry into shape? How pliable is it when dried?

[@prestonwillis9413]

I'm casting the letter P that I carved in wood. Would food oil work to release it??? How long does it take to dry?

[@mist_oldskoolakatherollinr616]

Yes it would x

[@suzannahseidel6031]

About 1 hour to set and remove.

[@dulcemedrano2755]

Why can't you squirt it straight on to the wet soapy mold?

[@sanjayrak]

What is blue liquid

[@Aangel452]

Thank you for sharing, great silicone tutorial.

[@sandovaledgares]

What is the purple liquid?

[@mmontagart]

Thanks for a great video! It will help me much.

[@cristiancornejo]

is the water hot or cold?

[@teneseebognot7346]

It's wet

[@francoiseveronstamp]

+cristian cornejo soapy and cold and wet. cold and wet sets the silicone.

[@monstercolorfunco4391]

+francoise veron stamp warm and wet, it needs humidity and warmth accelerates the chemistry. the video was not accurate.

[@francoiseveronstamp]

+monstercolorfun co re watch she says cold and wet hahaha..

[@francoiseveronstamp]

+francoise veron stamp ha you say it is not accurate.. i dont know i only worked with room temp silicone so far...

[@happyorangeanimation]

I'm just about to try casting sugar into it... I thought this kind of silicone could take 250-300C! we'll soon see whether it can take 150-200

[@T1iCanon]

How did it go ? I hope you didnt use sanitary one :D they stink like hell :D

[@happyorangeanimation]

There were a few bits of the mould that had thin walls (less than 0.5mm thick) that I had to squeeze very big parts through in order to get the hard sugar out of the mould. After a couple of casts these thin silicone films ripped open a little but I think that was down to the shape of the mould and lack of release spray rather than the silicone itself having bad reaction to the heat. The sugar was liquid and between 180 and 190C and otherwise has left the shape of the moulds unchanged :D

[@sergioaraujo8094]

achei otimo,mais gostaria que poderia ser traduzido em portugues pois gostaria de saber o nome do produto que foi colocado na agua antes do cilicone

[@InezDoesLife]

É detergente para a loiça.

[@maryviera9049]

Me encantaria poder realizarlo, pero no entiendo su idioma..😣

[@angelallarena1259]

Lo que no entiendo, es como quedó eso!!!

[@magikdust2095]

if you make this type of mould for casting resin, will the resin come out shiny?

[@sm870621345]

+Magik Dust I know it's been a while since you asked, but to answer your question, most likely not. While this method will work in a pinch, it's really not an ideal molding technique. Most proper molding materials will pick up the finest details (including that fingerprint you didn't notice)and reproduce the same finish as what the original piece had. Most molding silicones are pourable, or at least brushable, to pick up detail. This is basically like sticking clay to something and expecting a perfect copy, It's just not going to happen in most cases.

[@jedteng2650]

How to make it semi transparent?

[@bryantenpas8301]

Silicon is a metalloid element silicone with an "e" is what this video is about there is a big difference between the two. There is silicon in the compound silicone.

Why not use a paint brush to aply the soapy water instead of your hand. Get the nooks and crannies. Just askin'.

nice video...

[@barbr316]

She wasted some silicone on the first ball that she was trying to make and it looks like it’s going to take forever to make that mold and it’s gonna take a lot of silicone

[@MothsWing]

How can you color silicone?

[@darkwaffle69]

Because some people make silicone casts, not just molds.

[@MothsWing]

Exactly

[@jerrywhidby5259]

I have used food coloring for this.

[@Randomd0g]

I know the comment is very old but this may be helpful for people lol. From what I know you can add some acrylic paint and knead it in to color the mold.

[@Emmark1000]

bloody hell i started watching this hours ago and have only just woken up!!!!

[@RailandOak]

Silicon is a chemical element used in the manufacture of semiconductors (hence Silicon Valley). Silicone (with an e on the end) is an entirely different word with a vastly different meaning. Silicone rubber is a flexible elastomer. I believe you intended to say silicone. Since you're a "school" I hope you would fix it at least in the description and title (I realize you can not change the video). But it's been 5 years and you haven't fixed it yet so I suppose I shouldn't get my hopes up.

this is great alternative for latex! i use silicone too

[@chromosomeCreatif]

Doesn t work fine. Transparent silicone have nt more density. And white silicone make impression with a lot of imperfections. It s a technique for little and easy mold. Is better with maezena.

[@SWSimpson]

So, we should get it soapy and wet? Soapy and wet and thick. Don't dig your fingers into it. Keep it soapy and wet.... and thick.

[@teestjulian]

That didn't show me anything

[@geoffgeoff143]

Silicon is a metallic element. That is Silicone.

[@sandrachase68]

In the United states real silicone mold making is very expensive. you can also use corn starch and make the silicone into a puddy and make molds that way. I thought it was funny that the video is from a mold making school and they where using silicone caulk instead of silicone for molds.

Ria Kooijman this stuff sticks badly to latex gloves- and doesnt stick to soapy wet hands. Hence no gloves. It also has very little smell if it is true silicone.
