I'm doing and extreme Shiwoo mod, which I want to recast, as the super sculpey I like to sculpt with is not stable over time. My question is: I want to make a plaster mold and then use Flumo so it will be hollow, am I kidding myself? Aside from a four part plaster mold, I'm in undercut central right? And if I can't use a plaster mold and have to resort to PVC or Rubber, how the heck do you get the head hollow??? I'm still working on him, but here's the pics so far so you can see what I'm looking at. (Sorry I totally stink at taking pictures, didn't even realize there was that shadow that was hiding his right lower lip ) Any ideas?? Thanks!
Awesome sculpt- Look in the artist cutom BJD forum- there is a lot of mold info. I dont think though that plaster will give you the detail you want.
Plaster will slush out all of your details into a blurry mass. There's no way to cheap out on this one, sorry. : /
It wasn't the 'cheap' I was looking for, it was the 'hollow.' I realized I may have to use pvc or dragon skin, I'd use a polytek resin then, but if that is the only alternative, how do you do you get the resin head hollow molding like that???? Honestly, I've made porcelain dolls for years, and it is exactly like Flumo, it's hollow so no worries, resin doesn't do that.
Ah-ha! That is a three part mould. *nod* There's an excellent tutorial for that here, and several in the Artist Dolls subforum. :3 Basically, though, you make another mould bit that would be for the inside of his widdle headyhead.
^Indeed. You can even try with a two part mold I believe. With the doll I'm making, I put her head with the opening into the clay of the moldbox (after plugging her eyes and neckhole) and the idea is to put silicone over it, then flip the box over, pry out the clay, put in silicone that fills up the inside of the head, and you should have a two part mold. I believe Lolipop cast the head of her doll Coppelia in the same way. Picture: The box is wrapped in clingfilm to prevent the playdoh in it from drying out and cracking when I'm not doing anything with the box. Hope this helps you
yup, Shuri is right Here are some more pics, I hope they help you Put the head in the mold box, cover the eyes with clay so the silicone won't get in. The head lies on a clay ground, I used plasticine which doesn't dry. Then, put the silicone in and let it dry When it's dry, flip the mold over and take away the clay. You can leave the head in, build a new mold box and cast the second part. Because the head is still in, this is what makes it hollow! I didn't take a pic of the second part of the mold..now that you have both parts, just fill this part of the mold in the picture with resin and then put the other part on it(be sure it lines up okay! keys are handy for this, but I just drew a mark on the side and that also worked). If you see the resin coming out, then it's enough. Now, let it dry and take your part out, and cut out the eyes(do this when you take the head out, because when it gets hard, it's really hard to carve anything out). Same goes for the headcap Good luck!
You know what I never understood? The eyes. If you plug up the eyes with clay, don't they then cast covered over? Or am I just missing something that should be extraordinarily obvious?
@Idoru: the cast does have the eyes closed,but if you add the clay from the inside of the head, like I hope is somehwat visible in the pics I posted? It comes out exactly like that,so the part of the eyes that was filled up is slightly lower than the actual outside of the eye, so it's really easy to just cut that out and still have the eyeshape you sculpted I'm sorry if I'm not being very clear,it's hard to explain, really something you don't fully understand until you've done it..
ShuriTigerH and Raouken: Thank you so, so much!! the tutorial and the pictures really helped me understand! I greatly appreciate your advice! Thank you so much!! Petiteloli: Thank you! That's what he's suppose to look like, I love cats and Therians (cat people) I can't wait to cast his head (well when I'm done with it at least) and then make a whole bunch of different colored cat heads! Idoru: You have to put clay in the eyes or the rubber would go through them and then you wouldn't be able to get what you cast out of the mold cause it would hook on the open eyes like a lock, Like the letter 'H' if the eyes created the opening, the - part of the 'H', and you tried to pull out your side of the mold, the 'I' part of the 'H' the - would connect the rubber together like an 'H' with your head trapped in between, the whole 'H' being rubber. (don't know if that's even understandable, but I tried >___<)
sorry to be OT but i just have to ask because it's really bugging me.... I noticed a lot of dolls have these splotches on them after they've been sprayed with primer/gesso.......what is with that? does the spray not cover as neatly as i thought it would? please explain someone out there....
that's because after they've been sprayed you can see the imperfections (bubbless and gouges etc) those parts are then sanded. that's what the blotches are.
BubbleGumGoth: you're welcome^^ Love what you're doing with that head, BTW, though I'm not sure how you're gonna cure the super sculpey. Doesn't seem like such a good idea to stick a resin head in a 250 degrees Fahrenheit/130 degrees Celsius oven... I'm gonna try when casting my little one's head to remove the clay from the eyes after the first half is molded. Then put on mold release on the silicone that's in the eyewells and pour the other half of the mold. I'm hoping that will give me an open-eyed cast . And Maggot is right although in Raouken's pics the blotches are patches of epoxy she put on at the last minute to smooth out any imperfections. On my doll's head it's just the sculpey coming through the spray putty after sanding.
yea, in my case it's epoxy like Shuri said ^^ it worked really well for some final smoothing,expecially since it sands so well It did make him end up looking a bit like a dinosaur though, with the green stuff.. XD
@bubblegumgoth: yeah, I understand WHY you do it, I just mean, if you were to cast dolls in the volume a company does, it isn't practical to cut out the eyes of each one, is it? . _ .;;
ShuriTigerH: I was going to mold it soft, I know they do that when they make porcelain dolls, is there any reason it can't be done with super sculpey? Thanks for the compliment!! I couldn't put it in the oven, the resin would warp, you can warp a resin head with a hair dryer, and that's nowhere near 250 degrees. Joss_Amazing:Thank you so much!! I appreciate the compliment! I wasn't sure people would like what I was doing to him, thank you!
I know this! You plug up the eyes for casting the first part, like in the pictures. But after that you take out the clay, so when you pour in the second silicone part, you'll get the eyewell and hole. The resin won't fill the eyes and it'll be like the original piece. Also, it's good to put keyholes so the two silicone pieces lock together. And since silicone bonds to itself, you need to put vaseline(or something) on the first part before you pour the second. Hope that's helpful^^ Hmm...really cool sculpt, but why not sculpt a new head altogether? Then you get that cool head and you get to keep your Shiwoo...
Great sculpt Just a couple of days ago I had great results boiling a resin head (incidentally, it was also a feline modification) with some pretty thick sculpey parts added to it for 30 min. in the microwave (I used a glass bowl with enough water to cover the head completely). The resin got a tiny bit soft, but not nearly bad enough to warp or damage it. The scupey is now firmly attached and easy to sand. I was really worried about it warping, but am very happy with the results and plan to use this method again in the future Hope this helps, ~Sarah~
Well, it’s not quite finished yet, but since you requested it, here’s a sneak preview I sculpted the cat features onto a resin head that I cast from another of my sculpts and I am still working on sanding, details, and sculpting the ears. My favorite thing about her so far are the tips of her little fangs barely showing You can see more of what I am working on here: http://www.denofangels.com/forums/showthread.php?t=105088&highlight=unique
Oh she's beautiful!! I love your sculpts!! I'm going to be doing things like that too, (sure when I get around to it) Thanks for sharing!! She is beautiful and looks very graceful. I'll be putting little fangs on mine as well, but that will be awhile away yet. What was the resin type you used to case the head you molded on?
Thanks I used Alumilite's White Resin. It works very well. Here's a link to the product: http://www.alumilite.com/checkout/index.php?cPath=22_30&osCsid=f757e5e7d91083f528aa366ada7617b9
OOOOH! So that's how you do it! I was wondering! I was like, "I know you plug it up so it doesn't make a horrible mess, but then how do you not have resin in the eyeholes?" And now I know! Thanks! X3 Very nice head. I think the boiling method sounds like a great idea! O:
I love that mod you're doing. He reminds me very strongly of Stalking Cat (who I've had the pleasure of meeting)!
How do you plan on baking it? the resin cannot go in the oven...or did you want to cast it while it is soft?
Thanks for the compliments guys!! Licorice-embryo: I'm going to try it soft first so I can save the Shiwoo head.
OMG you put sculpey in the microwave?! *horror* *seizure* I seriously would not reccomend this... XD It says so right on the package.... .... Boiling sculpey in water is a valid way to set it (as is a heatgun) but I would not reccomend boiling it in a microwave. Next time, boil it in a pot of water on the stove.
and you can try boiling the water in a bowl in the microwave ,take the bowl out when done and then put the clay/part in!
Hi It doesn’t say anything about using the boiling method as a way to cure it either, but it works wonderfully. I think the microwave warning is for the Sculpey alone without water. I would never dare doing that for sure It might blow up or something *blink* The nice thing about the water is that it gets rid of most of the fumes. I have had terrific results every time (this is how I cure most of my doll parts). Boiling on the stove works too, but it takes much, much longer and is much easier to burn or boil the water away if not watched really closely (I sometimes use the stove if there are any metal parts in the clay such a tin foil or wire armature). In the microwave I just set the time and let it boil
Well, if you say so and want to risk weird reactions I just still would not reccomend it. Sculpey only really creates toxic fumes if you burn it, also breathing in the dust from sanding is like the WORST, they forget to tell you that on the package, it's like UBER toxic to breathe in XDD . I'm just a safety nut I guess, sorry to be the voice of motherly doom *laugh*
If you go with a silicone cast in the end the uncured silicone may eat through the uncured SS. I think someone else said that they tried to cast an uncured SS head and the silicone destroyed it. I know it'll destroy unsealed paper clay or plaster. You should be able to boil the resin without it getting too soft... and so long as you aren't tossing it across the room or anything it hardens back up extremely fast without warping. :3 I don't think a plaster mold with a flumo cast will give you the detail you'd like... you'd probably have to go back in and re-cut things to add detail before the flumo completely dried. A pint of silicone from smoothon.com costs about $20 plus shipping. two pints should be enough to make a mold of his head. A pint of resin costs the same and out of a pint you should have enough for several castings so that you're sure you get as good a cast as you like. :3 I use the smoothcast 300 and the oomoo silicone. both are measured by volume so it's pretty easy.
