Description
Thanks to , whose Vurmling head i used for this tutorial and thanks to hubby who assisted me by playing the hand model!
You can't make your own mold/cast or don't want to waste money and material? I offer you my help! Like for i can make molds and casts from YOUR object for the fraction of the price you would spend on materials! Send me a note!
Have you seen my other tutorials?

Why cant it be an air hardening clay? will something happen?
π: 0 β©: 1
It is easier to remove soft clay (like plasticine) and you wont waste material since you'll most likely have to throw out the air drying clay after molding - but you could use it if you want. As long as it is sulfur freeΒ Β I didn't make a good experience with ad-clay and thought to point it out to use something different.

This is very helpful! But what do I do if my object is hollow, can I still use this method?Β

Oh! I didn't know you could cut silicone molds in half, I thought they were too flexible, I figured it would leak! Very cool that it doesn't! Thank you for sharing this. Β

You can! Secure it with a rubber band to keep it closed. Or, depending on material and thickness you might consider giving it a shell for support, so it doesn't wobble around and keeps its shape! Also, if you are using drinking cups as mold box, you can later get a new cup, coat the outside of your finished mold with talcum powder and slide it back into the cup for added support.

Oooo! Good to know! c: I'm still not sure if I want to involve any molds in my art dolls, I really like unique faces. But! I would totally use molds for accessories for the dolls. Your little guide here is PERFECT for casting little findings for jewelry. Β

I just wanted to pop in and say that I found this tutorial extremely helpful! I just made my first mold for an art doll of my own, and it turned out great, probably because of this tutorial! XD

I freaking love you for all of your tutorials!Β Β
Most people that make cool dolls like yours like to keep it all hush hush but you do all these lovely tutorials and even sell diy kits. I'm so wanting to buy one for a good practice of assembling a doll before I sculpt my own. I just need to decide which one I want and save up. >w<
But also I've been looking for stuff on resin casting for a while because I've been wanting to make my own garage kit figure. So thanks again!Β Β

Thanks so much!
I'd suggest you get our DIY-Wolf for practice. It is the latest addition to the DIY-Kits we offer and the best designed doll, very "user friendly" regarding sewing, painting and assembling.

This might be a derpy question but does the clay need to be baked or does it matter?
π: 0 β©: 1
Not derpy at all
π: 0 β©: 1
Hehe. Thank you for the reply! so for a one part mold it doesn't matter? I know I got a quote from you but I then thought how many I actually wanted to make and of different things so thought I would give it a shot first before I slammed you with orders lol.Β

Cheezez I was just about to fix my reply - I mistakenly thought I am answering to the new submission from today. Freak. I'm so sorry. My bad!
For a 1p-mold you don't have to necessarily bake it - if you are sure your mold will turn out just as you planned. But to be on the safe side, i'd suggest to bake your original - just in case your mold turns out bad.

Oh there's no need to apologize hun least now I know if I ever need to make a two part mold

I am about to start making some monster/creepy dolls....would it be better to make the claws/paws a solid resin for durability? Or doing a couple coats of this would suffice?
π: 0 β©: 1
I suggest to cast all doll parts in resin for maximum durability!

This is so helpful! Thank you for sharing, but I do have 1 question... Can the molding components used in this tutorial be used with polymer clay like Sculpey? I want to make molds for future use (because I'm too lazy to sculpt a similar object from scratch lol) but I wanted to know if Mold Star was safe to use when making a mold for polymer clay. Thank you again! Β

Yes, you can use Mold Star on Super Sculpey. All clay is fine, as long as it does not contain any sulfur! Mold Star (and most other molds) does not cure in any way on contact with materials containing sulfur!

Awesome! Thanks a ton!

Great tutorial, I would ask you what silicon do you use to make your molds ?
and what release agent do you paint on your sculpture?
π: 0 β©: 1
I use "Mold Star 15 Slow" from smooth-on. Check out their homepage, they have many different molds for any purposes. www.smooth-on.com
My release agent is called "Ease Release 200" from Mann Release Technologies. Also here, check out their homepage to find the right release agent for your project! www.moldreleases.com

Ah, such a lovely tutorial! I love how you always try and help out other artists. <3 You're amazing.
Β
(Psst! Just a small fix for your tutorial- any clay that has sulfur will impede the mold making process. Sulfur disturbs the chemical reaction in silicone, and will make the mold cure improperly. So any clay but sulfites. XD Learnedthatthehardway,oi.)

Thank you for the hint! I finally found the file to fix it!

forgot to ask 2 more things..
1. Β what clay and resin do you use
2 in the first picture, why do you have a blue and yellow bucket of mold?
thanks for taking the time to answer my questions!
π: 0 β©: 1
In the tutorial i used sulfur free clay. If you are molding, both original object AND any unbaked clay that you might use during the molding process MUST be sulfur free!! Otherwise the mold material doesn't cure and stays sticky!
I use polyurethane resin.
The mold material consists of two components. Only mixed together, the chemical reaction starts to set in and makes it cure!
π: 0 β©: 1
what 2 components do you mix together to create the mold though, if you don't mind me asking? if only 2 things needed, why were there 3 cups of stuff in the tutorial though?
π: 0 β©: 1
The mold material is consisted of two components and need to be mixed together to make the chemical reaction work! (To make it harden.) A and B Cup contain the two compounds, the C cup is used to mix both together!
π: 0 β©: 1
ok thanks, but whats the name of the two compounds and the stuff to mix it together???( i didnt see it on the tutorial) OwO
π: 0 β©: 1
Mold Star 15 Slow
π: 0 β©: 1
so if " Mold Star 15 Slow" is used in 1st cup, whats used in the second cup?
π: 0 β©: 1
The second cup contains part 2 of the mold, like it says in the tutorial.
π: 0 β©: 1
oh! so you buy the mold it comes with 2 parts?
π: 0 β©: 1
yes, exactly. every mold and resin comes as a two part compound. only through mixing the compounds together, they start to work.
π: 0 β©: 1
oh ok. thats what i misunderstood! thanks !

Very welcome

great tutorial. if you don't mind be asking a few questions... what mold do you use? also, is the head hollow ( to make the head hollow i usually just form the head than get a knife and make a hole in the back, i know that's a bad way, how do you do it?) and is the head baked or not baked when doing this... finally.... in paragraph 1 of your tutorial, what is the " demolding process" and how do you do it.Β
also, the second row of pictures, and the picture in the middle looks like a giant marshmallow... Β
π: 0 β©: 1
The mold is use is called "Mold Star 15 Slow".
The original head wasn't hollow, but the copies where!
To create a hollow head, i use to sculpt the head over a solid base, covered with tin foil. After baking the sculpey head, i can easily lift it up from the base! Check my tutorial out, to learn this technique!Β
Demolding is simply the removing of the original object out of the mold. This happens by cutting a one-part mold open (shown above, last row, middle picture), or - if you use a two-part mold - by separating the two pieces!
π: 0 β©: 0
I have been sculpting the pieces to a future doll for a while now, and all I have left are minor details.Β
I see that you are using Mold Star. If you don't mind sharing, which one are you using?Β
