Images and details galore
New images and further detail of the iron casting process is on my flickr page. It's very brief. I hope to post up a more detailed explanation soon, as well as pics of the finished products!
Cast iron, rambling, sculpture and who knows what else which might come to mind
Here's the furnace before:
And here's the furnace after:
And here are my head models, made in modelling clay:
The middle guy was made in air-hardening clay which wasn't ideal, particularly if you've got what are called "undercuts". The gurning guy with the teeth above the middle dude is an example of a model with undercuts.
Effectively, these heads were put into resin-impregnated sand when it was still soft, so all the bits inside the mouths behind teeth and up the noses etc were captured in the softness. But once the resin sand hardens, about 30 mins to an hour later, you've got to get your models out. If they're made with something that's hard, like wood, for example, you'll wreck the resin sand mould by forcing it out. So I was able to pick out all of the bits of still-soft clay after the resin sand hardened, thus keeping the undercuts intact.
More info on how they became cast iron later!
Indeed, forthcoming posts include a How To for those inexperienced in the great art of iron casting.
My favourite part of the week? Breaking Agas with a sledgehammer. Now why didn't I get a shot of that?
