Hi- I've been slow on this project, in the possibly of producing bronze-casted large bird feet, but I have gotten back at it now and have at least made up an armature. See pics.

Now that I have a foot made out of copper wire I am now trying to decide if I should add either a hard wax, or add a heat harden-able clay to it. I like the idea of dipping the foot repeatedly into liquid wax, to build up thickness, which I would then sculpt/add texture, or else add clay and do the same and then harden. I am trying to decide which would be better for sand casting. Would someone have a experience as to which would be preferred for sand casting?

Also, I am leaning towards sand casting this (actually two feet, as well as the leg portions) in bronze. I like the idea of a silicone mold, so I could more easily reproduce them (lost wax process), should I have difficulties casting, but I am stumped as to how to cut the silicone mold open to release the sculpture. This is a complex shape to me and even trying to make a sand cast to the irregular parting lines would be difficult but doable, I think.

If I decide to dip in wax is there a preferred type? I purchased some some time ago, blue wax sticks, which it says on the box are hard-wax. I may not have enough though to fully submerge the sculpture and would have to buy more if this is OK to use.

Anyway thanks for any comments/suggestions as to how to proceed to try and duplicate the birds feet shown in my earlier posts.

Thanks! Mario
