Moldmaking - Tiki Technical Tuesday 35

- Опубликовано: 2 окт 2024
- Break out the plaster buckets and mix up the silicone, because for this Tiki Technical Tuesday it's mold making time!
Join in the adventure as we pour plaster, mix silicone, and cast an army of production molds for the Volcanic Vapor mug! Keep in mind, the way I make molds is only ONE of the many ways to do it. Any mold that casts cleanly and has no undercuts is a good mold :)
As always, please subscribe (if you haven’t already) - put questions in the comments and I’ll do my best to answer them!
Thank you so much, I have spent whole day today to watch your films!
I’m so happy you found my channel! Thank you for watching.
Two weeks!!! I can’t wait that long! Can i come fan them?? 🤣
Patience is the first lesson in ceramics 😂
Back again, tomorrow is plaster pouring! tunings out model surface finishing only took 1 day lol, I'm working on two different designs at once . I've been watching these videos as soon as I get home from the studio and before I leave in the morning. I think that means I'm protected by plaster "mishaps" by the tiki gods ?? yes?
also for anyone working on a dwindling budget like myself, the dollar store had a lot of the things I needed for refining, plus mineral spirits from Home Depot, no way around that lol
Best of luck with the molds! ✨🤞✨
Great videos. Thank you
Thanks for watching!
These are great. Can you please provide the name of the wood, screw type and size, and general dimensions of the boxes? Attempting to recreate for a similar sized project. Thank you for doing these.
Thanks! the screw size is dependent on the thickness of the plywood you decide to make your boxes with. Check out this moldmaking video, it has more info:

Pimp shirt! I totally dig the blue and green shirt.
Nice and beautifully calm educationative youtube video 😂 IDK what i've just said, But i meant thank you 😇
😂
Thank YOU for watching!
can i send you a piece to get molded and casted? its a ceramic step for a deepend of 1960"s swimming pool.i have one original and need 3 duplicates ...lmk if there is a way to send u a photo or shipping address to ship to..mahalo
Aloha! We don’t do any outside mold commissions - we’re too small of a studio.
why don't you use fiberglass instead of silicone?, it's cheaper and do the same job
Fiberglass to make the molds? I need a flexible mold material to make the plaster molds. Also: fiberglass resin would need a booth for the fumes, and I’m. It set up for that in my small studio.
finally someone who understands that molds should look neat and clean.
Ha! That’s how they work best!
This dude is the Alton Brown of the ceramics community.
Ha! Thank you 😄
this is exactly what I said.
Can you cast a plaster mold out of clay? Or does it have to be fired to bisque or even glazed first? Is plaster of paris good for making molds?
Aloha! Not sure what you mean for the first question, but I definitely don’t recommend plaster of Paris for molds unless you have no other options. Pottery plaster is much better quality.
Can you use any soap? Or Vaseline? Thank you!
As a mold release for plaster? You can use Vaseline - but mold soap is the best bet.
Another amazing TTT! Can’t wait to try my hand at silicone master molding. Thanks for sharing your knowledge 🤙🏼
🤙
I didn't notice keys for the bottom mold when you poured the sides. Is this done after?
Good eye! Yes, for the bottom piece I add round keys in the plaster after I pour the first two pieces.
Hi. I really like your work - it's clean and precise. Very nice. Good educational material. The only thing is - in your little character that you hung on the wall - limited edition - I am not sure what you called him - I would have taken it a step further. I mean, it is just a nick nack as it is - why not turn it into functional art by making it into a planter or something? And I love you baby - but this mug is just plain ugly!
Hey - not sure which wall hanging character you’re writing about - but thanks for letting me know it’s ugly 😆
What kind of release do you use on the monster clay? I made a few handle models with it, but have yet to make a plaster mold from them. Thanks in advance!
Aloha! I coat the finished piece with Krylon crystal clear, and then (following advice I got from Monster Clay several years ago) several coats of pledge furniture polish
So much to be said for a good mold/moldmaking skills. It's just as important, if not more than the sculpture. Without it, you have nothing! Bravo!
Question on that silicone, since it sets so fast, is there considerable shrinkage, like if you were to add UFC and extra catalyst in other products? Or have they worked it out somehow for minimal shrinkage?
Great tips this episode, always learning new things! 👍
Good question on the silicone! It takes 24 hours to fully cure - it just kinda gels up after 15 min (or so). I'm guessing it is set up like that because it's really a brush-on silicone. I use it for my poured molds because I like the 40a shore hardness. It's a good stiffness for plaster casting.
What would be the best SUPERMARKET available mold soap release or similar material, oil spray etc?
I really don’t know, as I’ve only used the mold soap I have. Folks use Murphy’s Oil Soap - but be sure to research it and make sure it would work for you
why does he make a plaster mold, then a silicone mold of the plaster mold? Why the extra mold?
I have always just made one mold. the silicone, or urethane mold. has always worked great.
For slipcasting, the mold must be made of plaster. I could just use the one plaster mold I made in the beginning of the video - but that means I could only cast one mug a day. The silicone mold lets me cast multiple plaster molds, and that means I can cast multiple mugs in a day.
I get so excited for Tiki Tuesday!!!!! I love seeing a true artist work there tiki magic 👍😎🗿🍹🙏🏽🏄
Thank you so much!
How does the wooden box hold together? I guess you build a new box for each project? Where do you buy the mold straps? I appreciate the videos. Thanks.😀
The boxes are custom made for the mold pieces, and I hold them together with pocket screws. The mold straps I get from my local ceramics shop www.georgies.com
How much do you find it costs you on average to mold a new mug and make all the production molds? Love your technical tuesdays!!
In the end of the video I cover the amount of plaster and silicone used for the molds - but it varies from project to project depending on size and complexity
This is so neat. I definitely need to have a better setup. I wish I had seen the first part where you made the keys. I just use a pc of broom handle or one of the dowels on my pouring table. But yours are so much better. Could you please tell me where you get your silicone? I must not put right info in my search engine because it doesn't give me this. Thank you so much for the tutorial.
If you watch my newest moldmaking video I try a new technique for the round keys
Hi do you sell molds
No we don’t - we only do molds for our projects
I need a mold maker
Wish I could help! We don’t take outside commissions
I’m new
Aloha!
Hi , I want to buy belt which is used in this vedio , can you suggest me store ...
here you go!
amzn.to/3hMxdwY
you're adorable (and very creative!), even cuter at 1.5 playback speed
😂 thank you!
Thanks for the video. They help so much! What kind of plaster do you use? Cheers!
I use USG No.1 Pottery plaster for my slip casting molds
You did some prying there! Did the monster clay bend or get damaged?
the original sculpture made it out in good shape - in fact, the first shot of the video with me holding the sculpture was recorded last (after had pried it out of the plaster mold) :)
This is great! Im in the special fx make-up business, so mold are nothing new. But its a joy to see these, its always a great pleasure to see somebody else enjoy working on something they hold dear.
Thanks! As an old makeup FX guy, I am grateful for the years I spent making molds of monsters and dead bodies 😄. I did need to modify my methods a bit for ceramics, though.
@@vantikistudio Thats what I love about this series! I never worked with ceramics before, but your series is very detailt and even teaches me a ton! All the love and support from the Netherlands!
How do you know when the molds are completely dry? Thanks!
Good question! they no longer feel cool to the touch. The old school method it to hold it against your cheek - it shouldn't feel cool at all.
I didn't know about the windex/water trick!
neither did I! Thank god for Instagram artists willing to share tips (like @hammerlyceramics and @mitchellspainceramics - who both know WAY more than I do)!
@@vantikistudio Is there a specific ratio of water/windex? I have used isopropyl alcohol for popping bubbles on resin when pouring into silicone, but have not tested that for plaster. I assume it will be fine as it just evaporates, but wanted to take good notes for the water/windex mix you found. :)
Who’s your source for the Smooth-on silicone?
I get mine from the nearest Reynolds Advanced Materials www.reynoldsam.com/location/
What are your PRONOUNS?
he/him - thanks for asking!
Thanks
Welcome :D
What clay are you using for the first half of the mold, why doesn’t it stick to the Monster Magic clay?? As per usual great video cool stuff!
And as a follow up you might know the answer to, could you use a ceramics, green ware clay, for the half mold? Thanks!!
I use a inexpensive water based ceramic clay for the mold walls.
I know of folks who have molded green ware - but it is challenging. You need to release it VERY well as the plaster will want to bond with the porous surface, and you need to be EXTREMELY careful to avoid any undercuts.
Hey!! I really appreciate the response! Thanks a bunch wish me luck on my casting adventures. I appreciate your approach, the fact you don’t hate keep and how you approach community! You’re an inspiration to me!
