Playing with Mermaids

Inspiration comes in strange places.  With the excitement of Austin Wizard Con looming, I have been playing with all kinds of ideas for the table display and the idea of little knick-knacks to show.  And since I follow a ton of very talented artists on Instagram, I was inspired by them to try something completely new for me:  molding and casting.

So I watched a few videos on YouTube, and now I’m an expert.

I won’t do a full DIY step by step, since I don’t really know what I’m doing and this is all new to me anyway (trust me, this is one of those situations where you have to just jump in and try it).  But I’ll give a rough rundown of the basic steps, just to show you what was involved…

Step 1: Sculpt something.

I used Super Sculpey, and tried to come up with a little sculpted version of the mermaid girl Myla & I made.  (I realize she looks very little like the original, but Myla said she was cute, so I think it’s okay…)  Since kids have a natural magnetic attraction towards clay, I sacrificed a handful of Sculpey and let Myla make her own mermaid.  (She modeled her after a character on Doc McStuffins, who is not, in fact, topless–but she couldn’t remember what her top looked like, so she just gave her breasts.  I’m not sure if I should put a censored black bar over kid-sculpted breasts?  I just go with it)…

Step 2: Make a mold.

I got my kits from a company called Smooth-On (who have TONS of great videos on their site).  I won’t give you every little detail on this, since the directions are really easy (and on the box)…but the basic idea is mix This with That and pour.  (Plus, if I told you everything, I’d ruin all the messy fun for you.)  The main thing I learned during this step:  make sure you mix it REALLY well.  If you don’t, it doesn’t set right.  I made mine from silicone rubber in a plastic cup.  I nearly didn’t mix enough for the tail, but it turned out alright.

Step 3: Cut your sculpture out

You know that bit of instructions that you think, “Ah, that’s not a big deal, I’ll just sort of wing it”?  Well, turns out sometimes they tell you those little tips for a good reason.  When I put my sculpture in the cup to mold it, I forgot to mark on the cup where the back side of her was.  So when it was time to open her, and I “guessed,” I guessed wrong, and sort of sliced up her face.  The stubby arms were apparently a little too weak for the whole process and broke off.  And the body crumbled because I hadn’t fully cooked her.  But the mold itself turned out fairly good.  And Sculpey can be touched up a bit, so I patched her up and fully cooked her, and she was just fine.

Step 4: Pour plastic/resin into the mold.

The first go-round, I tried a liquid plastic kit from Smooth-On.  And along with my repeated advice of making sure you mix everything the right way, I’ll add a couple of pointers I learned:  First thing is that it’s probably a good idea to wear gloves.  Initially, I gave that bit of advice a big ol’ “Pshhhht, whatever.”  But plastic nearly ALWAYS gets on your hands, and it feels super creepy, like when you get superglue on your fingers.  Blecch.  And later, when I tried pouring resin, I had a bit of a leak in the silicone mold (it was a different mold, and I had two “air holes”), and it leaked hot resin ALLLLLLLLLLL over my work table.  Trust me, that’s not fun at ALL.  So my bit of advice there?  make sure you don’t have a spot in the mold that might leak.  And lastly, GIVE IT TIME TO CURE.  I’m very impatient.  But hot plastic hurts.

Step 5: Plastic mermaids!

So I messed up quite a few mermaids, but after some trial and error, I was able to get a few decent-looking plastic mermaids!  Fun!  I couldn’t figure out why their faces were bubbly, though, until I looked closely at the mold, and realized that the mold itself had bubbles set into it.  Whoops.  Later I made a better mold, and made it smaller and on its back, so I wouldn’t waste so much silicone rubber.  That helped clear up any bubble issues, and gave me a much clearer mold.  Apparently, having her on her back, and pouring the silicone in the corner and letting it sort of “seep” into the face on its own is the big trick with that. (I HAD done that the first time, but she was positioned upside down, and all the details of the face were on the bottom, leaving lots of chances for air to get trapped in there.  Whoops.)

Step 6: Paint that junk

So with a handful of funky mermaids, I decided we should go ahead and paint’em up.  Why not?  And since they came out wonky, I let Myla have a go at them, too.  7 myla painting

I had a little trouble painting on the actual plastic with acrylic paint.  (Myla had no complaints.)  I even tried a basecoat of brown primer for plastic, but it just didn’t look so great.

photoApparently, again–the trick is very careful mixing.  In my very limited experience, I’ve learned that if your mixture is off, it can do all sorts of wonky things to your cast.  I haven’t tried painting these resin casts yet (I’ll try that later), but I’ll be sure to post the outcome!

With new projects, there’s always a level of intimidation for me.  That casting kit sat in my art room for about 5 months before I actually got the courage to try it.  But you know–when you do, it feels awesome to have finally figured it out!  Even if you end up with an school of mutated fish-women, you can’t really consider it a failure if you’ve learned something.

So jump in and try something new!  I promise, it’s worth it.  Wonky mermaids and all.
