Alright Friends!
Let's talk about silicone and mold making.
We are using two different kinds of silicone today.
That is rebound 25 and this is moldstar 20 T
and really the difference between them is that this takes 30 minutes to cure.
This takes six hours.
If you don't have a quickener
So for the purposes of this tutorial we are going to cast
mine in the fast curing silicone since we don't have enough to do all of them in that and
set these ones up for later. So we are going to build a box around the
sculptures that we made using cardboard because I just have a ton of cardboard on hand.
This the poor man's way of doing it which means you'll be able to do it.
Yay! yeah, using cardboard and hot glue really there's no way to be classy about this.
Let's do it!
Hi friends, so quick thing about cutting
Just a little tip.
What you want to do is lightly go over your cut first.
Then make a deeper cut the second time
that gives you more control because otherwise you're just going to be putting a
lot of pressure and it's hard to control yourself when you're doing all that so
that's how you cut shit.
(Cheyenne) So what we're doing here is we're just literally hot
gluing cardboard strips around the flashing directly to the glass.
The hot glue makes a nice watertight seal
It will come off the glass later if you have your faithful scrapey tool.
like I do
or determination. make sure that all of your edges are really feel
tight with hot glue. Or you're gonna have silicone everywhere and it's gonna be terrible.
All that space in there that's wasted silicone. That is a crime my friends.
Do not commit it. When possible. (Madison) pay attention to where you are putting your stuff.
That is the moral of that story.
Hey guys, Hot glue is hot!
(Cheyenne)The first thing we are going to do after we finish filling our boxes is to spray mold release.
It is smooth-on's ease release 205.
it's a universal mold release and it's just to make sure that your silicone doesn't stick.
(Madison) Make sure to generously spray it.
Yes!
To make sure the silicone mold is easier to identify when mixed properly
We're going to be tinting parts A and Part B different colors.
So when they make purple, because we're using red and blue.
That's how you know you mixed it properly.
That is only in the silicone that I am using because it is naturally clear
The silicone she is using, the rebound actually comes in pink and white and just makes a lighter pink.
Follow the instructions on the bottle
because this one says stir A part thoroughly before mixing part B.
This one is Stir Part B thoroughly before mixing part A.
So just stir all of your silicone before mixing it together and then stir it some more.
Also gloves, please wear gloves. It will get messy.
Also please make sure to get the right sized gloves.
Yeah make sure you get the right sized gloves because you wanna you want to be sure that
the gloves fit on your giant man hands
Have a lot of tongue depressors handy always. I stole mine from my doctor.
(Madison)And that is for you, for the blue.
(Cheyenne) oh great!
(Madison) If you don't have a gram scale you can get tiny cups this size and just
fill them both up equally and you should be fine.
Then pour them into a slightly bigger cup
Also if you're using the entire bottle...
Then just pour the entire bottle in. It's what we did last time.
So the pigments that we're using are the Silc Pig.
They're the Smooth-On brand of pigments for silicone. It's just like the tube of sample coloring
But this teeny bit of coloring goes a long way. It's lasted me I've had it two
years. (Madison) and you still have like an entire thing (Cheyenne) I still have an entire other one.
Have rags handy.
I find the best way to get silicone off of things is a dry paper towel.
(Madison) Pay attention to the pot life of your silicone because that will tell you how much time you have.
The pot life is how much time you have before the silicone becomes unpourable.
So I am pouring it from one center point and letting it spread out from there.
This makes it harder for air bubbles to form on your mold.
Rather than just drizzling it on everywhere. Just pick one spot and poor, and let it spread.
We are just repeating the process for the different molds.
I have had nightmares before about silicone not curing.
It's true, I'm pretty sure if you scanned my brain it it would have liked a whole section just dedicated
thinking about silicone
Let me put it this way. I love it, but it doesn't love me.
So mine will be ready in about half an hour. Madison's will be ready at my bedtime.
So here we have the molds.
Curing up Nicely.
So it's been a little while
and we are coming back to my molds because they are done.
They are very done.
Hers are not.
(Madison) And I made the mistake of touching them.
I just wanted to poke it!
You just rip em apart.
All that glueing that you did. You just destroy it now.
If you released it properly it should slide right off.
*Triumphant Noise*
(Madison) oooouu, that came out good girl.
(Cheyenne) Came out pretty good.
There is always going to be some kind of cleanup that you're gonna have to do.
But as long as you get all of the pieces out of the mold.
You will have a clean prosthetic.
Look how clean this one came out.
*Triumphant Noise*
It's wonderful!
Ok, Great!
That came out really good.
It's really good.
and now (Madison) Pokey thing? I will clean them out while you clean up.
Poke thing and brush.
You use a pokey thing and a brush to clean out your molds.
Then get your trusty scrapey, to clean your glass plate.
You want to make sure you get the molds as clean as you can.
That will mean you will have a better prosthetic with no detail loss.
As much as it may hurt you. To scrape away the scultpure that you obsessed over for a couple of hours.
You're going to have to...
You're going to have to do it
(Madison) You now have a permanent replacement that you can make a backup from.
True
(Madison) Before you make any prosthetics with it and that way the perfect copy is
ready to go if you want to keep it.
So yeah, Onto the next step!
what we are doing here is we are preparing the mold for the material
We're using Johnson paste wax and you just brush it in really well .
(Madison) and the trick is make sure you brush it in well.
But don't put so much that it obscures all the details that you've worked so hard on
(Cheyenne) Yes!, Less is more
with with the paste wax that's for sure, but you wanna get it everywhere.
