Bronze Casting - Bronze Axe

[nghtmrofdarkness]

Do you fire the crucible in a kiln before you use it, or just use it right away?

So this is what actually takes place when you make a axe on a crafting table.

Cone 10 stoneware clay mixed with a little bit of sand to aid in filling cracks that might appear through vitrification.

What's your recipe for crucibles?

Fascinating video! I'm interested at trying my hand at this myself (after I've done the appropriate research). I'm wondering -- did you use gunmetal for the axe, or did you make your own alloy? Also, is the mold made from a silica based medium?

[macaulayman]

That is THE most primative setup I have ever seen. But it does show that casting can be done with very little. It does look like you know what you're doing. Great stuff.

[leeviajero]

I've been thinking about doing the same thing, actually. Are there any sources you found particularly helpful in learning how to do this?

Well, that proves that you are well skilled in this art:)

Looks simple enough. Used coal and blower for heat?

[kurakusername]

Nope, charcoal. Coal wouldn't work too well, it would melt and stick together, and the clinkers would mix with the bronze. Also, it's not simple, though it certainly looks that way! Getting the metals to 1100C with dung-doped clay and charcoal, in an oxygen reducing fire is pretty challenging at times. You also have about 10 seconds MAX once you stop pumping air into the fire to pour, otherwise the bronze is too viscous to pour.
