  • - All right, the first step is over.

  • You know, we've cut her ears off.

  • This is a witch without ears.

  • Now I wanna lay her down, and obviously her big shoulders

  • are in the way, but I wanna lay her down

  • 'cause I'm gonna take a little alginate snap mold

  • of this area that we just did.

  • So I was thinking you could lay her down on anything.

  • I was thinking a bag of white clay, but that is too tall

  • to get a nice horizontal angle for her.

  • So I happened to figure out just a minute ago

  • that this nice pillow of Accu-Cast, which is our alginate,

  • is just about the right height.

  • So I'm gonna put that there, I'm gonna put a little form pad

  • on it to protect our sculpture,

  • and I'm gonna stick her like that.

  • So that's pretty good.

  • What I have ready at the table

  • is everything you're gonna need.

  • I have plaster bandages, buckets.

  • I have water sources ready.

  • I have alginate ready, white clay.

  • I have my famous clay cutter that I believe you saw

  • in the last episode.

  • And we're gonna get to work here.

  • So the first thing I want to do, I'm gonna cut a nice

  • thick slab of white clay.

  • I wanna get my mold knife out

  • which is here.

  • So there's a fettling knife, this is actually called.

  • With a fettling knife, we fettle,

  • and here's our slab of clay.

  • I'm just gonna cut it in half and all I'm using this clay

  • for is to prop her up so that she's not

  • going all over the place while we're trying to do that.

  • Now we can take our adjustable clay cutter,

  • which you just saw me use,

  • and we're gonna change to roughly about 1/2 an inch.

  • I'm gonna take another slice off my clay,

  • and move that aside.

  • And all I'm gonna do is, I've got a straight edge,

  • I'm gonna cut a wall, cut some strips,

  • about an inch and a 1/2, what have you, it's not critical.

  • I'm gonna make a little bit of a wall around here

  • so I don't have to make a gigantic mold.

  • I don't have to get alginate all over my sculpture.

  • This is a very crude wall.

  • I'm not gonna get too carried away with it.

  • I am thinking about what my final piece is gonna be

  • and how big it's gonna be.

  • And I'm also going to look at the ear

  • and make sure for the final buck,

  • the positive that this ear will be

  • permanently sat on and completed,

  • that there's enough plaster around the ear.

  • So what we're doing is we're taking a mold here.

  • We're gonna make a plaster piece that this ear will

  • then sit on and be finished

  • and then a mold will be made on top of that.

  • So we're making a plaster piece that has

  • all the witchy textures that I'm gonna match this down to.

  • So I'm just making sure as I'm making my little mold here,

  • nothing has to be perfect,

  • but we'll work as cleanly as possible.

  • I'm just making sure there's enough plaster

  • and witch texture represented

  • around the ear.

  • And we can make a cut here, 'cause that's all we need.

  • Put that together.

  • Again this is crude, but it's fine.

  • We can clean it all up later.

  • I'm gonna add a tiny bit here because,

  • as I pour my alginate, that's the dip

  • where it's all gonna run out.

  • So I'm just gonna add a little bit there.

  • So I mean that looks like a healthy amount of detail

  • and plaster and clay around the ear.

  • When you're working mold walls like this,

  • try not to do what I'm doing right now.

  • Try not to get in there with your fingers

  • and make all kinds of finger printy stuff.

  • Try to just use your clay as a wall, you stick it,

  • you leave it alone.

  • All right, you butt the next one up.

  • You maybe smoosh a little bit together.

  • But try to work cleanly.

  • If that's your wall and you stick it there, you're done.

  • Don't get in there, and I see all kinds

  • of beginning mold makers get in there

  • and they're doing this and trying to make it all perfect

  • and they end up with that.

  • They end up with this horrible lumpy mess.

  • So here we have Accu-Cast alginate,

  • prosthetic grade alginate.

  • You can use any brand of alginate.

  • My recommendation, honestly, for this work

  • is buy a nice cheap alginate

  • because basically we're making a lot waste molds.

  • We call them waste molds because you're gonna pour

  • one thing out of it and throw it away, okay.

  • So don't buy prosthetic grade cream,

  • you know the very expensive stuff.

  • This is perfectly fine.

  • There might even be cheaper solutions, I'm not sure.

  • And we're not gonna need a ton of this.

  • That's probably more than plenty.

  • This is alcohol.

  • I'm smoothing some clay, and cleaning a little clay dust.

  • You could use water if you were in love with your sculpture

  • and didn't want to smooth it, but I'm also smoothing

  • some sculpture in here as we go.

  • Okay, so there's that.

  • We have our alginate, we have our water source.

  • We need another bucket for plaster bandages.

  • So we'll just put a little water in there.

  • Hot water will make your bandages go faster.

  • This is not hot water.

  • So always alginate, always add

  • water into the powder, never the opposite way around.

  • It's completely different than stone.

  • Stone you add powder into the water.

  • This is the opposite.

  • So you just mix that up.

  • Thick is fine for this.

  • You're just capturing not a lot of detail.

  • You're just getting a form basically.

  • You want what detail is there,

  • but that's not even finished detail yet.

  • That is the rough approximation of finished detail.

  • You're gonna see as we go through this process,

  • you're gonna finish all the finished, finished,

  • finished detail on the separate little molds.

  • So you're not done sculpting.

  • There's still sculpting to be done.

  • So there we are, nice and creamy.

  • It could have been thicker, it's fine like this.

  • I'm just gonna put it in there,

  • and really kinda mush it down,

  • make sure I am getting whatever detail there is.

  • You could put it in with a brush if you'd like.

  • Again, you're more worried about basic form.

  • So this getting thicker already.

  • And the next thing we're gonna do once this thickens up

  • is just put a little plaster bandage shell around it

  • to hold it in place.

  • What we're gonna be doing in this process

  • is a lot of little mini lifecasts like this.

  • Once we cut this apart and put it in the water,

  • we're gonna take all the clay pieces off except,

  • well, you'll see.

  • The head part will be the first part we finish, the cowl,

  • because that'll be the first part we put on the actress

  • will be the overall headpiece.

  • All the other pieces are gonna key onto that.

  • So we will finish off the headpiece first

  • and then we'll slowly start adding back the other pieces

  • and taking little molds so that they all

  • fit together with their wrinkles.

  • It'll all come clear as we do it.

  • I know right now that might seem a little mysterious.

  • You could use gloves for this if you wanted to.

  • I find that this is such a gummy material

  • that I find it hard to work in gloves with this.

  • But this is perfectly safe, inert.

  • You could put this in your mouth

  • although it doesn't taste good.

  • They have separate dental alginate for mouth castings

  • that has a minty taste.

  • This tastes like chalk.

  • And I'm just waiting for it to set up.

  • Now we're gonna do the same thing to the other side.

  • They actually give ratios on this for how you mix it.

  • I just mixed it by eyeball

  • 'cause I've been doing it for years.

  • But on this particular brand, they say

  • a good average consistency is approximately four to one.

  • That would be two ounces of powder

  • to eight fluid ounces of water,

  • four ounces of powder to 16 fluid ounces of water,

  • eight ounces of powder to 32 fluid ounces of water,

  • and so on.

  • So they actually give you ratios on this one.

  • That's news to me.

  • You'd have to do a test and see what their ratio gives you.

  • Obviously this could have been thicker

  • than what I made it but it's fine.

  • You wouldn't want it any runnier than this,

  • so you'd have to try out their ratios in a little cup

  • or a little test batch to make sure that their idea

  • of what's good is not too runny.

  • It's definitely gotten to be like jelly or jam

  • on the top here.

  • It's not running anymore.

  • It's not gonna go anywhere, but it's not quite setup

  • enough for us to do our thing yet.

  • While I'm waiting for that to completely harden,

  • I'll rip up a few plaster bandages.

  • We're not gonna use many.

  • We won't use more than a roll.

  • I like to make them two ply thick.

  • Some people go three, some people go four.

  • By two ply I mean I fold it over once,

  • so it's two bandages instead of one.

  • I think we went through some of this on the lifecasting

  • when we did Cynthia's hands.

  • It's kind of whatever you like.

  • I do at least two play.

  • I haven't used a single layer plaster bandage

  • in years and years and years,

  • probably not since I was first starting out.

  • But you could fold this over once,

  • you could fold it over twice,

  • you could fold it over four times,

  • whatever gets you through.

  • Personally in this instance, because we're only really

  • trying to capture a form here,

  • you could have made six layer plastic bandages

  • and just done one layer on here and been done.

  • I like just the two layers to capture all the detail

  • and get around all the nooks and crannies and all that.

  • But then you could start backing it up with four layers,

  • six layers, whatever, just to get through it.

  • So this is a holdover of lifecasting

  • which is what we're basically doing here.

  • Okay, our alginate is setup here and we're gonna get

  • to the plaster bandage part.

  • But because we're at Legacy Effects today,

  • I thought I could show you a different way

  • to go about this tool.

  • This is my famous adjustable clay cutter

  • that we love so much.

  • If you don't have one of these or don't have access

  • to one of these, lots of times you see the

  • two dowels with a wire between them, a garrote, if you will,

  • or even if you won't, that is a clay cutter.

  • How you get a nice controlled thickness like this,

  • if you just take that and go across a block of clay

  • this gives you a nice, smooth, even slab.

  • There's another way to go about it and I just happened

  • to find these here at Legacy today

  • because they have all the fancy stuff,

  • this is another thing you can do.

  • This is a board with, they have machined aluminum on here,

  • that's 1/2 inch, you can see that, it says 1/2 inch.

  • They also have ones that are 1/4 inch,

  • and you can make it whatever you want.

  • Now if you don't have access to nice machined aluminum,

  • and who does, you can just glue some paint sticks here.

  • You could take some paint sticks,

  • pretend this is just a board,

  • you can just glue paints sticks, hot glue them down,

  • until they are the desired height.

  • Right, so three, maybe four paints stick makes 1/2 an inch.

  • So take that away, and put that there instead

  • on each side and you've got 1/2 inch clay cutting board.

  • So this is the garrote that I'm talking about

  • or the gar-rot.

  • It's a wire and two pulls, okay.

  • Cheap and easy, you can find these

  • at any sculpture house, any art store.

  • If you make a board with paint sticks

  • or nice machined aluminum,

  • you can put your clay on there like that,

  • you put the wire down tight,

  • and you just slice through

  • always keeping the wire tight onto there.

  • Then when you pull this off, upend it,

  • you have a nice, clean slab of clay.

  • I just wanted to show that for all you mold makers

  • out there, so you don't think I have something fancy

  • that you don't have.

  • 'Cause you can make this really, really easily

  • with a paint stick and a board.

  • Okay, back to this.

  • We are now ready to take this clay wall off, this is setup.

  • You can see it's nice hard, it's not hard,

  • the material never gets hard, it's always kinda squishy.

  • And you take your clay wall off.

  • Okay, and you can take some of this

  • little delicate stuff away.

  • That's not gonna buy you anything.

  • You can take a nice, sharp tool.

  • This is really jellylike alginate.

  • I'm not sure I'm in love with it, but it'll work.

  • It'll work just fine.

  • There we go.

  • Now we are going to put some plaster bandage around that

  • to make sure it holds its shape.

  • So we have our water, I have warm water this time.

  • Because I have seen the error of my ways

  • and instead of using these two ply,

  • I'm gonna put two together and have four ply.

  • Put it in the water, squeeze it out real good,

  • and I'm just gonna put it around the edge to start with.

  • Now all this is for is to make this jiggly jello here

  • of alginate just keep its shape.

  • Again two, two plys together makes a four ply.

  • Squeeze it out real good, you don't want it all runny.

  • I'm folding it over again so I literally have

  • an eight ply around the edge.

  • Make sure the plaster bandage is all meshed together

  • really, really well when you put it on there.

  • Make sure there's not a lot of air under it,

  • that it's all laying down nicely.

  • Now we're gonna cap that.

  • Now because I used so many ply together, that's probably

  • all the plaster bandage that I need on there.

  • I'm just using this extra piece 'cause this end

  • didn't get as much love as that end got.

  • You gotta make sure the children are all treated equally.

  • And we're just gonna let that set up now.

  • Now normally I would use extra fast set.

  • Today we're dealing with fast set which is not extra fast,

  • so we're gonna have a moment here.

  • Once this is set, we're gonna pull it off,

  • flip it upside down.

  • We're gonna put Hydrocal into it and make a stone positive.

- All right, the first step is over.
