Making DIY Silicone Moulds For Jesmonite Candle Jars (+ Vacuum Chamber)

[@MakeupMobster]

Can you just make a million videos about this? Lol! Your voice is so calm and soothing and I love your accent too. Plus you’re very informative

[@susanamarin7342]

You have no idea how much I’ve search online for a video like this one! Thank you soooo muchhh

[@MakeupMobster]

Me too!

[@MikeCashVT]

Thank you for making an informative and well-paced video!

[@MackieJackCreations]

Thank you for being so real, and sharing the flaws, as well as the accomplishments!

[@ashkcreates]

Thank you so much!

[@omarmoran3097]

​@@ashkcreates is there a name for the 3d print molds you made? I need to find them and make them.

[@milojah444]

Thanks for this video. I like your candid personality and it's nice watching you. I was wondering if you tried inserting a cylinder in the middle of your model container before adding the silicone, to reduce the bulk of the material on the inside of the finished mold. I would love to see that tested out. I hope you see what I mean but i'd be happy to elaborate more.

[@LaurentLamar]

Hi Ash! Can u please tell me what silicone you use? It will be very useful for me and I really appreciate your work and your help!

[@bhrigu22a]

Great video. All the best

[@MackieJackCreations]

Awesome job!! Looks very clean to me, and should make beautiful vessels. Thank you for sharing. Blessings!

[@angelivelayo9449]

Hi Ash! Thank you for this tutorial🙏I also want gto learn how did you make the mould box? Do you a tutorial for it?

[@ilovetrees33]

So nice bro… thank you

[@sbhm1108]

So informative so helpful thank you

[@BMills-nb6ub]

I love your video's :) Some great information!

[@sweetladya8590]

Omg that is so impressive

[@quissum6418]

super helpful! Going to buy a vacuum chamber now and try it out. Thanks for sharing your experience.

[@Shakalowski]

Nice job keep on!

[@MSTAMRO_Organic_Skincare]

Thank you so much for this awesome video. I have been searching for it for a while now. I wanted to order from Amazon and there are different types -soft, strong, semi-strong… which would be better for the molds? Thank you so much.

[@ashkcreates]

Hi there! I tend to lean towards softer silicone for my moulds because the shape of my jars need me to fold the mould over itself in order to release the jar. For example I used a Shore 20A silicone for this specific mould. Just make sure that the walls of your mould are thick enough to support the weight of itself otherwise it might have a chance to misshapen since it is a softer material. Best of luck!

[@dank420bluntz]

This was so helpful!

[@juups4857]

Hi Ash, can you let us know which shore rating this silicone is?

[@kellyjean4981]

Wonderful, thanks for sharing your experience

[@metamour]

Hi Ash. Which "shore" did you use, because you talked about it in the video, but you did not mention the shore rate ;-) Thanks, and good work!

[@karenwoodruff-Travelinstyle]

Great video, you are hilarious

[@burakcanarnms3118]

Hey, great job. I was wondering one thing. You poured silicon also inside the jar. However, in the final silicon mould, there is a gap the top of silikon so you can easily take jesmonite jar out. How did you do that. After making silicon, did you cut it, or while making silikon did you put something to make?

[@DR76900]

Which silicone brand did you use?

[@jsmm84]

Hello! Do you know if silicone stick to other silicone ? I was making two silicone molde and Run out of silicone on the second and wonder if i make new silicone it sticks to the one that is dry. Thank you

[@spacejam242000]

Hi Ash, I want to make a mold just like this for candle jars. I’ve been searching for so long for a flexible silicone that can be folded back like this. Can you please provide the shore rating for the one you used? Thank you it would be such a help :)

[@ashkcreates]

Hi there! It's Shore 20A for this specific silicone. Hope that helps and best of luck with your mouldmaking!

[@eldenl1]

I have seen other people put the poured mold into the vacuum chamber to force the bubbles out. Would that not work for this?

[@ashkcreates]

Hi there! I haven't had spare silicone to test this out yet, but I might try it someday. In theory it should work, I've just been concerned about my master object and frame collapsing under the vacuum. Stay tuned for when I eventually test it though!

[@TheKiddSocks]

Hi, which printer was used to 3D print the jar you liked and sprayed yellow?

[@ashkcreates]

Hi there! I got mine printed at a local 3D printer shop and it was printed using the SLS method. Their spray paint option was an 'automobile-grade' paint option which I chose because apparently SLS leaves a coarse surface which can't be smoothed via sanding. It was pricier than I was hoping for but I was really happy with the end product! A more cost-effective alternative would be printing via SLA and it'll leave you with a smooth surface even without painting.

[@Sandra.Sandy.Robinson]

If all else fails, read the instructions.

[@LaurentLamar]

Hi Ash! Can u please tell me what silicone you use (the name of your silicone, company name)? It will be very useful for me and I really appreciate your work and your help!

[@MakeupMobster]

Weird question but can you put the mold in the vacuum chamber?

[@ashkcreates]

Hi, thank you for all the lovely comments! Based on what I've seen in other videos it should be yes. I chose not to place the moulds or master object in the vacuum chamber because I didn't have the budget or time then to make new ones should the pressure cause them to deform or break. I'll try it out once I have spare ones to see what happens! 😂

[@MakeupMobster]

@@ashkcreates ok interesting. Can’t wait to see the results. I know how you feel. Just purchased some silicone but I’m scared to use it! It is rather expensive

[@MakeupMobster]

@@ashkcreates and you’re welcome. I can’t wait to see more videos

[@Kickupflix]

So, what do you make the cups out of? A harder Silicone or concrete?

[@ashkcreates]

Hi there! For the actual candle jars that are made from these moulds I use Jesmonite, which is a resin with similar properties to concrete and that is also fire-resistant. You can see my process of making the jars here: kzbin.info/www/bejne/iabTlYSPpqakbqs

[@Kickupflix]

@@ashkcreates I tried looking for Jesmonite, but its expensive and they don't sell it anywhere in America. Do you know how many cups it would make?

[@ashkcreates]

Ah yes it's a tough one to get in your area! It really depends on the shape you go with and can range from as low as 10oz of mix per jar to over 16oz. The smallest kit I can get officially is 3.5kg (123 oz), though I've seen kits on Etsy that are more like 1kg (35oz). Either way that should give you an estimate of how many jars you'll be able to make. Concrete would be the next best option for you if Jesmonite is tough to get, here's a video showing the (slightly different) workflow of working with concrete: kzbin.info/www/bejne/p3iod3aCoriIsK8 Best of luck in finding something that works for you and hopefully Jesmonite starts distributing there soon! (Also I hope the ounce conversions are correct, I usually use grams 😅)

[@Kickupflix]

@@ashkcreates Thankyou. Yea for some reason when I saw your video on it. I kind of like the product. But I found a place in Canada that sells it.

[@ashkcreates]

Amazing! Hope you have fun trying Jesmonite out :)

[@marisajames8158]

Great video, thank you. Would. 3 D mould work, printed with PLA. Also do you leave the mould in the silicone for a longer period?hank you.

[@ashkcreates]

Hi Marisa, sorry for the late reply! My answer based on my personal experience - yes , BUT it's been hit or miss! I've found that PLA objects that have sat around for some time (a few weeks to a month) have worked, however if the piece was too new it caused (platinum) silicone to not cure. I'm not an expert in material science but I think the object was still offgassing something that caused cure inhibition. I would suggest doing a patch test like what I did at 10:18 to see if the silicone you're using works on the specific PLA object you're looking to work with. The duration of time to leave silicone in the mould depends on the silicone you use! You have to refer to the manufacturer's instructions for specifics, I've used silicone that takes less than an hour to ones that took over 18 hours (yikes!) Hope your PLA object works and good luck!

[@walruschicken]

What brand of silicone are you using? Can you send a link? I’m used to using smoothon but I would like to try out different brands

[@JonBrowning760]

I'm wanting to make candle vessels. Do you know how to make the mold so the center is not solid silicone? Like the pink mold at the 5 minute mark. Can you recommend a specific silicone that is on Amazon? The choices are overwhelming.

[@ashkcreates]

Hi Jon, amazing that you're looking to explore the craft! I think it was the camera angle but the pink mould actually has a solid silicone centre. I haven't figured out a techinque for making a mould with a hollow centre yet! It's something I will look into because it will save a ton of silicone, though I will say one of the advantages of having it be solid is that your internal cavity is more likely to stay in shape. The only silicone I've tried so far that is on Amazon is from Alumilite, they have a pretty good library of tutorial and explainer videos here on KZbin that could help you out with choosing which type to go for. Alternatively if you would like to get started with pre-made moulds, Modern Craft Labs / Makershapes have some options that you can consider. Best of luck with your projects!

[@JonBrowning760]

@@ashkcreates thanks for responding. I did some research, u can use something like a wood dowel glued to a board, then use something like a piece of plumbing pipe for the outside. Could add a bas relief silicone liner inside the pipe for texture or images.

[@silviasantos3461]

Preciso deste tipo de forma.

[@keymarieharlii]

Ah, I just realized that I forgot to order a mold base to keep the shape of the mold 😂. You should sell them!

[@ashkcreates]

Oh no! I might consider doing that once I'm certain that they're a useable product - stay tuned!

[@daddywoofdawg]

doesn't his voice sound like George Takei?

[@sennaners2428]

Why purposefully hide the type of sillicone you're using to make this mold? I feel like that part is pretty important.

[@ashkcreates]

Hi Sennaners, thank you for your comment! The main considerations for deciding what type of silicone to use are at 08:07 onwards for comparing platinum versus tin-cure silicone, and 28:16 onwards for shore hardness. Other considerations are scattered throughout the video. I do believe that focusing on these general principles is more beneficial than using exactly what I used. After all, crafting isn't one-size-fits-all, and the shore hardness or silicone type I may like to work with may not be what others like or want to use in their specific situation. Learning the principles will allow you as a creator to adapt them to your specific use cases and circumstances; be it the type of object you're creating a mould for, or what silicone you are able to source based on where you live. And yes, there will be trial and error throughout that process but our mistakes tend to be our greatest mentors! I will be continuing to share more videos going into greater detail of these considerations and principles. In the meantime, best of luck in applying them to your own projects!

[@THE_KORE]

You were almost ready to say the shore flexibility of what you were using for the silicone but end up moving onto something else in your conversation. The silicone you are using is it shore A 30

[@Blingblingbabe_]

Hot silicone would be a good option for the floating situation. Loved the video, i'm on a discovery adventure too, creating molds and that stuff for concrete vessels

[@ashkcreates]

Oh interesting! Do you mean a hot glue gun or actually heating up the silicone rubber before pouring? I haven't got round to trying a hot glue gun in case it gets stuck on my master object 😅 Great to hear from other crafters on a similar journey, thanks for dropping a comment and hope your moldmaking is going well!

[@Blingblingbabe_]

@@ashkcreates hahha yeah! Hot glue gun. But now that you point that... it could damage your master piece. Question, how do you get that smooth on 3d pieces? I'm printing with an ender 3 pro and tried different techniques at post processing like painting and sealer, but those lines are still there 😢 Loved you tu channel, i'm subscribed!

[@ashkcreates]

Thank you so much! Ah yes I started with 3D pieces that had the lines and ran into so many issues with trying to get rid of them. I gave up after a few weeks and ended up getting it printed in a different print type (either SLA or SLS with spray paint). That type of printing needs a completely different machine so you'll have to consider a 3D printing service to try those out - just a warning that it is quite a bit costlier! If you'd like to stick to your current machine I think the key is really LOTS of layers of sanding and painting. It's difficult to get rid of the lines if there is a cavity though (e.g. making a jar). If it helps this was one of the videos I looked at when I was troubleshooting my lines: kzbin.info/www/bejne/r4OnhKmtrd96g9U Hope you're able to figure something out that works for you!

[@lesleyyoung9600]

Can I buy one of these molds from you?
