Curious about the process of making plaster and silicone molds for ceramics & slip casting? Well, today’s Tiki Technical Tuesday is for you! Gather round and watch as I make a plaster mold of the Dead Bastard Mug, and then nearly go crazy making a silicone master mold of that plaster mold. Silicone can be stressful, and when you don’t have enough of it things get EXTRA PANICKY

You must have a rare personality type: creative, artistic, able to play and imagine; combined with orderly, industrious, technically minded, able to stick to repetitive and tedious tasks over long periods of time, business and efficiency minded. You really have many strings to your bow, hats off to you

Thank you! We do wrestle with a lot of the issues most artists face: insecurities, impostor syndrome, burnout, etc. I’m not terribly business/efficiently minded, but I have a great partner who is 😄

@@vantikistudio Dear Henrik. I finally got to make the production mould with the silicone. I made a small 2 part silicone mould of a handle. My husband made the boxes out of MDF, and the MDF had a coloured paint on it to stop it from absorbing moisture. When I hot glued the plaster parts onto the MDF, I put a blob of the glue on the centre at the bottom of the plaster part. We marked the boxes orientation just as you said. When the silicone was set 24hrs later, I took the boxes apart and turned the silicone mould upside down and poured the plaster into it. When the plaster was set, I took it out and the two parts did not fit together. There seems to be some distortion. My question are: when you hot glued the plaster piece to the foam board, where did you put the hot glue? Doe the thickness of the bottom of the silicon moud make any difference to the plaster mould? Because I think my silicone mould's bottom is too thin, is only 1cm thick. Do you think the thin bottom has anything to do with the distortion? How thick is the bottom of your silicone moud? Thank you in advance. CC

Thank you for these videos. It will be a long while before I can get back into ceramics (homeless). When I was really into it, I tried to find someone to make my molds for me. I never did find anyone, the ceramics supplier had a contact, but he wouldn't call me back. I tried making my own, but had no idea what I was doing. Nothing came out. I lost so many original sculpts that I finally gave up.

That's an awesome process. A way to guarantee you have enough silicone is to measure the volume of your empty mold boxes and use that number so you will end up with and extra amount equal to what you are molding you could also measure the volume of what you are moulding via displacement to get a more accurate number by subtracting your two numbers

@vantikistudio 2 года назад

Yes! I sometimes use plastic bean bag pellets to fill the molds before the silicone to accurately give me volumes - but mostly I just eyeball it and live dangerously 😂

You can use urethane for molds. It is less expensive, but it behaves very differently than silicone. You need to be extremely careful about proper release, moisture contamination, and proper mixing

@willallen9409 3 года назад

Awesome job as always! Only VanTiki can make it look so easy. Question, after pouring mold sections I am always nervous to leave my plaster walls in contact with each other (even with mold soap) as I feel like it won't come apart. With enough mold soap can the plaster stay in contact with each other for days? Just making sure I didn't see that incorrectly.

@vantikistudio 3 года назад

Good question! I really don’t know if the plaster walls grab more if you leave them together longer. I usually spend at release two days making multiple piece molds, so I’ll open a mold two or three days after pouring the first piece

Hi, great video! Very informative and detailed! I was wondering whether the original model you sculpted was just dried clay or some other material? I have a sculpture that I have been making out of clay originally intended as a one off piece but I have since thought I'd like to make a slip cast mould of it so I can make more. But I am wondering if building a wet clay wall onto a dry clay sculpture for the 2 part mould would even work. Thank you if you are able to help.

@vantikistudio Год назад

Thank you for watching! My master model is sculpted out of a wax based modeling clay called Monster Clay. Since your model is a dry water based clay, you can seal it with a clear acrylic spray, and build up the mold walls with a soft modeling clay (like clean clay) - this way you won’t get too much moisture re-introduced into your master model.

It really depends on the size of the price you are casting, the orientation of the part in the mold, and if you have a “jacket” or rigid form around the silicone to keep it from distorting (this is the purpose of the plywood box).

@flynryan3053 10 месяцев назад

me agian, If the silicone level was a little too low, or to economize could you drop in some inert material(other than old silicone), say marbles, or cured silicone calk cut up, to bring the level up?

@vantikistudio 10 месяцев назад

You definitely can - but keep in mind how that object will behave when the silicone is curing and when you’re casting with the mold. Marbles would most likely sink, and if they are near the casting surface they may cause issues with casting.

@zielijo1 3 года назад

Could you warm up the silicone to decrease the viscosity?

@vantikistudio 3 года назад

Maybe? It sets so quickly I wouldn’t want to risk it. The viscosity isn’t really an issue for me - as long as I have a beefy stir stick! They have other less viscous silicones - but they are not as firm.

@StoneAndersonStudio 3 года назад

Hello Mr. VanTiki! Thank you so much for this fantastic video. This video series is a wealth of knowledge! I wanted to ask if it’s a bad idea to make thin jacket brush-on-style mother molds instead of thicker box molds like these? Most of the ceramics people I know make mother molds similar to the way you do in this video. Seeing as silicone is very expensive and I want to make quite a few silicone mother molds, would it be a smart idea to try the jacket mold method, or do you find this mold making method to be more convenient/reliable for reasons I don’t know? I’d really appreciate your thoughts/advice about this. Thank you so much!

@vantikistudio 3 года назад

You can definitely go the jacket route. I find in my practice that they may not use as much material, but they do take me more hours to make. Also, you need to make the jacket out of a rigid material (like plaster) and the molds can get heavy fast.

I’ve done everything you’ve said and made my first plaster mold, with the intention of making a silicone master and then plaster production molds!

I’m very excited and can’t thank you enough!

@vantikistudio 2 года назад

You totally can test your original plaster if you want to make extra sure. I usually don’t as I have to wait an extra week or so for the plaster to completely dry so it can properly slipcast and I’m usually in a hurry 😂

@badinstructor6806 2 года назад

This was a really fascinating process to watch, although slightly confusing since I'm not native English speaker and in my language, there's more (or different) names for clays. Like at first, I thought you were using something like pottery clay to make a "master" mug and clay walls, and was confused on how it didn't just dry, but then realised you're perhaps using something more like a modeling clay? Something that in Finnish is NOT called a clay, but a "modeling wax"

@vantikistudio 2 года назад

You are correct! I am indeed using a modeling wax to sculpt the original master mug. I use it because it does not dry out, and it holds fine detail very well.

@GlitchCityPromo Год назад

$500+ worth of silicone later... Woof. I do silicone mold making on a much smaller scale and end up using a gallon kit about every few months. Can't imagine the feeling of pouring 2 gallon kits in a day or two. I've seen a technique of brushing on a silicone mold until the piece has no undercuts, then using plaster to fill in the rest. That's probably the technique I'm going to try since it's cheaper and the plaster will act as a mother mold so no need to keep wooden mold boxes.

@vantikistudio Год назад

Yes - it can definitely be stressful to use such expensive materials! The silicone I use is actually designed for brush up molds. I weigh the cost of the time I'd spend in making the plaster jackets and doing the brush up. In the end, I like the form factory of the wood jacket box molds, and they are easy to store.

Can you please tell me what kind of clay you use! Thank you in advance

@vantikistudio 3 года назад

Which clay do you mean?

@regularguy8592 Год назад

can I use Murphy soap for mold release, which I already have? where does one buy this Georgies soap you speak of?

@vantikistudio Год назад

You can totally use Murphy soap - it’s basically the same. Georgies is a ceramic supplier- www.georgies.com

What kind of clay do use to make the parting lines? Is it ceramic clay.? I used clean clay for the first mold 1/3 that I believe is wax base and on my second half to create blocking/ more parting lines and pour more plaster on it . the clean/modeling clay ( plasticine? ) resists and won’t stick to the plaster so I can’t make parting lines for my 2nd / third half. I’m sure it’s water based but ??? And have access to ceramic clay.. so in short 🙄what clay will stick to the plaster to create my paring lines and still resist the poured plaster so I can make 2-3-4 part plaster molds Thank you.

@vantikistudio Год назад

Aloha! I just use an inexpensive white ceramic clay. This is Wonder White from Georgies. In the FX industry we used a white clay body from Laguna, and my friends also often use clean clay as well (but they are not making plaster molds with it - mostly silicone and epoxy)

@zielijo1 3 года назад

Why was the last piece not filled. How did you know when to stop filling?

@vantikistudio 3 года назад

if you mean when I poured the last piece of plaster - I know it only needed to be about 1.25" thick - I measured and marked the side of the boards with a pencil, and poured the plaster up to that mark.

@robslaphead Год назад

Hi I'm no expert but if you are making the boxes try not leaving so much areas free then when it comes to using silicone it won't be wasted. Ie try making the box really close to the main piece, try adding more bits of wood to bulk it out. Hope this make sense

@vantikistudio Год назад

Good point! I have to balance several factors when making the mold. I do find having at least a half inch between the wood and the model produces better castings than having extremely thin silicone bits. Also, my time is the most expensive part of the process, and that combined with using chopped up old molds to supplement/recycle the silicone used for the molds I don’t worry too much about larger sections of rubber in the molds.

@JamesErrLJones 2 года назад

Hi Vantiki. Could you tell us what clay you are using to build up your walls for the mold? Is it the same monster clay that you used for the sculpture?

@vantikistudio 2 года назад

Hey! For mold walls I use the cheapest ceramic water based clay I can get - in this case it’s wonder white from Georgie’s Ceramics

@tealkerberus748 3 месяца назад

Looking at all the bits you're trimming off once the silicone is set, do you put those scraps aside as filler for the next casting, the same as you added chopped up pieces of old set silicone to some of these? It's funny, I'm watching this three years after it was posted, but I'm feeling second-hand anxiety over the pour. You're a very good communicator! How many plaster moulds can you make from a silicone mould before it starts to wear out?

@vantikistudio 3 месяца назад

Great questions! Good gravy I can’t believe this was 3 years ago! I dont usually keep the little trimmed pieces from the silicone - but you totally could. I have a HUGE bucket of reclaimed silicone from old molds so I’m not that diligent about capturing every little trimmed bit. You can get a lot of casts out of a mold - how many? I really don’t know 😄. If you’re looking to cast hundreds of parts, I’d talk to smooth on about silicones specifically made for casting cement. They are made to handle the heat and abrasion, and should last longer than the rubber I use.

@vantiki why did you build the chair for the model? I have always just used 4 cottles. I'm curious to other advantages.

@vantikistudio 3 года назад

Good question - like you see in the video, the mold chair helps me to keep the cottles perfectly square with my model. and perfectly spaced from the edges of my model. It also holds the model perfectly parallel when I tip the chair on its side. In my experience when I just press the model into clay- build up the walls, then wrap cottles around it I end up with uneven wall thicknesses and the model itself sometimes is at a weird off angle.

@nathanielhunter1280 3 года назад

Oh i see what you talking about now. Nice! I'm sure this model was diferent to others you have made because it lays flat. Thanks for the reply! I'm loving your videos!

@mcallister167 2 года назад

Where did you get the silicone for making molds? What type/brand of silicone did you use? What brand of plaster did you use?

@vantikistudio 2 года назад

I'm using a silicone from Smooth-On - but as I say in the video, you should reach out to smooth on and request samples to find a material that best fits your project and budget. The plaster used in this video is USG Number one Pottery Plaster. Silicone I get from our nearest distributor: www.reynoldsam.com Plaster I get from my local Ceramics Shop: www.georgies.com

I'm going to make a silicon mold for the first time! Your video is really helpful. Thanks to your kind and detailed explanation, I always take notes and watch videos! I had a question while watching the video, and the mold soap I'm using is gel, but it looks like liquid in the video. Which company's mold soap is it? I'd like to prepare the same ingredients if possible.

@vantikistudio 3 года назад

Thanks for watching! I’m using mold soap from Georgies Ceramics, an Oregon based ceramic supplier.

@jacobfree2846 3 года назад

Is there a minimum amount of space you leave between the plaster molds and the mold boxes? I'm guessing too thin of space would make it easier for the silicone master molds to tear.

@vantikistudio 3 года назад

I try to never go thinner than a half inch.

@JamesErrLJones 2 года назад

Aloha Vantiki! Have you ever tried to make a 3-piece mold into a 4-piece mold by cutting a section with a thin saw after the mold is dried? I noticed a 45 degree angle after the mold was made and have been considering cutting it in half to start using it. Mahalo and I hope you have a lovely week!

@vantikistudio 2 года назад

You can totally do that! Anything is game if it makes a mold work 😄 Just be sure that the mold can still fit together tightly after the cut. If the keys on the intact part of the mold don’t let you squeeze together the two parts you cut, slip will flow out of the space left by the kerf of your saw. Good luck!
