Rainbow Dash Sculpt Day 4 by bigponymac Rainbow Dash Sculpt Day 4 by bigponymac
Day 4 - The Hollowing

I explained some of the steps in the pics. But here's some things that weren't explained.

That white thing in the background in the first pic is a piece of foam. Basically after I wired Dash off the clouds and the base off the plate, I put the piece of foam on top of the clouds and carefully flipped it over so I could hollow it out from the bottom. The foam gives something soft for the sculpture to sit on. After I got so deep, I carefully flipped it back over and hollowed it out from the top.

I hollowed out the torso and the head and began the process of putting her back together which involved a lot of scoring and slipping and caulking with soft clay.

It's still not perfect but it'll be easier to blend it when the clay dries out a little bit more.

Tomorrow I add the front legs and ears, detail her eyes, and maybe add her mane.

It is finished. Well, with the sculpting portion of it at least. [link]

Why hollow out the sculpture? Does the prevent cracking in the kiln? I'm not familiar with kiln work, but I'd love to try it. Would a wire mesh armature work instead? Would that be easier? I can sculpt with earth clay, but I've never had access to a kiln.

You're exactly right. We hollow out our sculptures because anything thicker than a half and inch has the tendency to crack or explode in the kiln. If there's places that can't be hollowed out (like the cloud loops) we take a needle tool and poke a bunch of holes in it and then smooth them out. The more air that can circulate in the piece the better.

I haven't worked with mesh armatures (or heck, any armatures for that matter) so I don't know how easier/harder that would be. I think it also depends on what clay your using. I think you would use the meshes for lower fire clays, polymer clays, or air dry clays. I honestly think the metal would melt or do something bad at the temps at which our sculptures fire. (They fire anywhere from 2200-2500 degrees F)

If you don't have access to a kiln you can use polymer clays (which can be fired in a conventional oven) or air dry clays. I also believe you can rent out kiln space if there's a local pottery/ceramics place around your location.

Thanks for the comment. I love answering questions. ^^

All I can say is GO FOR IT!

Sculpting to me is fun and relaxing. You should grab yourself some modeling clay and play around with it. You might be surprised at what you come up with! :)

And thanks! I'm glad I could inspire you!

Funny, but the instant I read wired I knew exactly what you meant. I must have seen some bad horror movie lately with something like that. (I've been doing a lot of RiffTrax lately.) It's too bad you have to cut a piece apart, but I suppose there's no other good way to sculpt it unless you treat it like a clothing pattern — and that's not amenable to the design process itself.

Do you score the edges of the cuts before reassembling the pieces or is it better just to use a little water and attach it smoothly? It must take extraordinary patience there.

By the way, what do you plan to make out of the scooped-out clay? (And you already know what the wrong answer is. :D)

There's no way around it when it comes to a piece like this. I probably could have used coils. That's where I roll out the clay into long cylinders and stack them on top of each other to make a form then blend and smooth it together.

I scored the edges of the cuts with a wet comb before I reassembled the pieces. If I wouldn't have there would have been no way the sculpture would have stayed together. The reason I used a wet comb is because as I scratch the clay, the water mixes with it and creates slip, which gives the clay something to hold on to when I put the pieces together.

The clay that I scooped out is a little to hard to do anything with. It will be put with the rest of my scrap clay, will eventually be recycled, and will be used for more sculptures.

The score-and-wet is what little I remember from 5th grade art class, but that was Cheap Ass™ clay so I wondered that worked with Orangestone. "Healing" the cuts must take some special care. Lately I've been fiddling with my blocks of clay while watching movies and such. Actually, the figure-drawing book I borrowed sucks when it comes to teaching drawing but has been very useful on getting Clayton's facial proportion's looking good. 's fun.

Long as the scrap clay doesn't end up as cupcakes I'll sleep easier. ;)

Actually it doesn't take much to heal the cuts. After I stuck them back together I took soft clay, caulked the cuts, and smoothed and blended until the cuts disappeared.

That's awesome that your playing with your clay. It's very relaxing. I get into such a zone when I'm working on my sculptures.

I could make the scraps into cupcakes for the hell of it. I think it'd be hilarious. lol
