Glad you're doing fine! We miss you and your tutorials here! Thanks for coming back to our lives! Hope you don't disappear again :)

[@LostWax]

Hehe, Yeah, I know, I am not very quick getting videos out....but I'm still here! I'll try not to disappear for too long😁

[@3DDruck_PV_CRCM_11m]

Yes, please don't go underground again. ✌ Is there something interesting new from your 3d printer?

[@JJ-up8ge]

Love ur vids! Your steampunk creations are absolutely amazing!!

[@LostWax]

Thank you so much, I appreciate the feedback!

[@Thanos_Productions]

OHHHH THAT LEGO FIGURE TURNED OUT BETTER THAN I THOUGHT

[@LostWax]

Thanks! I think with some practice you could get some really good results......

I love your joke delivery. your kind of “indifferent humor” hits right where I laugh the most.

Missed your great tutorials and awesome personality. Thanks for the info

[@LostWax]

You're welcome😁

[@DrPandemonium]

Thank goodness Chris is back (I’ve rewatched every tutorial you’ve posted while stuck in lockdown)! Another great video (you’re always really honest in your reviews) ... and like so many others I can’t wait to see/hear more about the knight armour 🙏🏼. Hope you and your family are staying safe during the pandemic 👍🏻.

[@LostWax]

Awww, thanks so much, yes, we are staying safe, all the best to you and yours as well!

Wow This would be really great for molds

[@vasilatos]

Thanks for this. Looking forward to testing.

[@LostWax]

You're welcome! It's really fun stuff to play around with (and useful too)

[@jherazob]

Oh yes, this stuff is legendary in the modeling world, great stuff! One thing people do with it is making a frame for the mold with Lego, they also make a piece to push the material in too, for the delicate details

[@LostWax]

That's a great idea, thanks for the input!

[@angelonweatherwax8083]

Thank you! I was trying to find good review for a while and you were thorough! 🖤 this helped a lot!

[@LostWax]

I'm glad it helped! Yeah, I watched a few and was still left wondering what the actual material felt like....

[@angelonweatherwax8083]

@@LostWax true! I wanted to ask: did the oyumaru leave any residue on the lego suit guy? I wanted to test the ozumaru on my shoe decoration (it is made from hard plastic a would make excellent base for earrings base) but I am still scared it will damage the shoe 👞. Also: did you try to cast UV resin from the oyumaru mold? I think it will burn through... Thank you so much 😊

[@LostWax]

@@angelonweatherwax8083 No, it didn't leave any residue, it seems to come off really nice and clean. Haven't tried with resin, so can't say about that one.

[@juliehamel8330]

I like the idea of a reusable mold 👍

[@JomasterTheSecond]

I've used Oyumaru for mould making for a long while - I use it for recasting Transformers and Gundam parts, though it's not the best for real complicated pieces.

[@citrusbutter7718]

I'm trying to make my own candy crush pieces. They're pretty simple shapes so i doubt ill need to worry too much about it not being that great for details. I just need something that acts similar to Amazing mold maker, can be wrapped around itself to form a tight-fitting shell, is easily cuttable, firm yet soft when cured, and see-through. I want to see the clay piece inside it as i mold it around the piece, and that i can cut it to take my clay out once it's cured so i can get 3D molds.

[@ruthbryant3929]

This is great! Thank you so much for sharing. I want to make shoe lasts for my dolls. Best,

[@LostWax]

Nice! Thanks for watching!

[@PrincessFidelma]

That stuff is remarkable!! For some reason I thought the business man's face would be in the mould, it was such a shock to see his blank face. 3:52 I recently had surgery on my forehead, that sounded like it, too.

[@LostWax]

Hehe, I guess it wiped the smile right off his face.

[@tomloveland2245]

Great video and review. I use this thermoplastic with Oateys Fix it Stick (hardware store epoxy putty) to make multiple versions of very expensive Warhammer models). Because of the mold line issue you found with the Lego man, the models aren't display quality, but can be filled and sanded or cleverly painted. Great way to save money when you need 3 Mega Gargants and the kit for 1 costs $160.

[@LostWax]

Nice!

[@patrickkavanagh7371]

This stuff looks cool I just bought some, thanks for showing the options here. Just what I needed to see.

[@LostWax]

Glad it was helpful!

[@pobbrett3244]

Would you be willing to to test this as a two part mould and try some resin in it to see if the exothermic reactions deteriorate the detail of the mould, would also be interesting to see if the clear stuff works with a UV resin and whether the light is strong enough to penetrate the rubber and cure the resin.

[@LostWax]

I think resin could get too hot for the mold to retain it's integrity- The idea of using clear with UV resin is an interesting direction, I could see that working really well.

[@jherazob]

UV resin is also exothermic, probably will work once then the mold will degrade too much to use again, not really a problem as it's easy to remake of course but still

[@beckymurphy4714]

Ooh. This stuff could come in handy for casting replacement limbs for model horses! And...knight armor!? What??

[@LostWax]

Yes, that sounds like a good fit for it!! And knight armour because, well, doesn't everyone need a set? Thanks for watching!!

[@samfenimore8868]

[@LostWax]

Yay! Thank you!

[@shuro3636]

It's great when you need to make a mold fast. Had my friend buy me some when she studied in Japan. If you have trouble finding Oyumaru you can look for Blue Stuff from Green Stuff World - basiclly the same stuff (but Oyumaru is cheaper - at least when you live in Germany)

[@LostWax]

Thanks for the tip!

[@ericsweetman9973]

What would happen if you made both sides of the mold with the same color? Would they stick together more? Or is the temperature difference the thing that keeps them apart?

[@LostWax]

The colour doesn't make a difference, you're right about the temperature being the key to getting them apart.

[@theintake8961]

Awesome video! Exciting product! Thanks for the video😎👍

[@LostWax]

You're welcome!

[@krbrickfilms]

Could you make a lego clone trooper phase 2 mold? Especially those from 2007

[@LostWax]

I think you could, but it'll still be tricky to get really perfect results....

[@thevalkyri]

So, that armour behind you... :D Are we going to get a tute?

[@LostWax]

You bet!! It's been a long time coming, it'll probably be 5 videos....which is why it's been so long since I last uploaded😁

[@johnhopkins6565]

Try using Vasoline or other petroleum jelly to coat the facing molds and they should come apart with no problem.

[@LostWax]

Nice tip!

[@Minedeployder]

Btw. Is oyumaru equals blue stuff? Can i mix them into 1 piece?

[@markthecruel1055]

Is Matt Berry getting residuals from Lego for them using his likeness.

[@GamingDad63]

Sorry for looking at the armour instead of you during parts of the video. Couldn't help myself :-P When will we see that build?

[@GamingDad63]

That winged Uni-Lion-Corn looks great

[@LostWax]

Coming as soon as possible, just gotta finish off the arms- hopefully the tutorials will start coming out in the next month.

[@LostWax]

Hehe, thanks for noticing!

[@dennisjohansen8490]

Seems like a good material for making a simple mold. I wonder if it would work for rubber stamping also.

[@LostWax]

Hmm, that's a great idea, though my first thought is that the ink might not cover evenly, the stuff seems a bit hydrophobic at first impression.....

[@spiranomad]

So, could this be good for cold casting coins?

[@LostWax]

I think it would work really well with flat objects, so yes, I'd say it would work. I'd say it really shines for if you just need to make a couple of something, if you are going to be making a lot of casts, a silicone mold would be better.

[@FlashRoxx]

This is available on Green Stuff world called blue stuff

[@JacknVictor]

It would give me nightmares drinking tea out of those mugs. For two reasons. 1- Those mugs are minging. 2- Tea is minging. (Its treason for a British person to say this, but there you go !) I use blue stuff all the time for moulding and it is amazing. I get very detailed Motu heads, weapons, etc using the blue stuff. I've even replicated arms and legs for test Motu-style figures. Also perfect copies of star wars 3.5" figure parts. I would advise using Lego and plasticine clay to get even two part moulds, there's tonnes of videos on KZbin that show how to do this.

[@layfonlin3147]

The reason why you didnt heard before is because it is only exclusively sold in Japan. Mainly is for kids to learn how to make moulds or learn how to cast.. It is very fun to play with.

[@norseridersNL]

will it still work if i drink coffee instead of tea?

[@LostWax]

Mmmm, doubtful.....

[@acexkeikai]

Would it work for resin?

[@LostWax]

I can't say, but if the reaction produces enough heat, it'll remelt the Oyumaru....

[@acexkeikai]

@@LostWax ah true that!

[@matthewboehlig1073]

I have the same tea kettle!!! @_@

I've had a lot of great cups of tea thanks to that kettle:)

[@petemalysewich6845]

Is this the same blue stuff that is sold by GreenStuffWorld? Just marketed different?

[@LostWax]

I'm pretty sure it is the same stuff, just different name.

[@honestfigurereviews]

Any idea why my 2 halfs stick together ?

[@LostWax]

Hmm, did you try making sure one half had a thin layer of water on it? I also wonder if dusting one side with a little talcum powder would help.....I haven't tried, but that's sometimes used in mold making...

[@honestfigurereviews]

@@LostWax yes I did and still stuck

[@redeath289]

Dose it work with air dry clay

[@LostWax]

I think it would, as long as you can get the clay out of the mold so it can dry.

[@Taurusus]

Don't forget to bump the quality up to 4k for all the floating dust action you can handle!

[@Bananacustardcostuming]

This is thermoplastic, I’ve used it to make fake teeth for vampire/monster costumes.

don't use Oyumaru for resin folks

[@lintasnews2949]

why?

[@5yearslateranimated712]

lintas news exactly why

[@JomasterTheSecond]

Resin heats up as it cures, therefore the Oyumaru will deform while the resin cures and screw up your final piece.
