Early steps to Resculpt "Grace"

I lost molds in a foundry fire. A Physicist in Virginia bought this casting of "Grace". I must make a mold of it, then repatinate before she goes to her new home. I will cast a positive in the mold and then begin resculpting. There is shrinkage throughout the lost wax bronze casting process, so I will use the positive as an armature and resculpt it bigger than the bronze in order to allow for the shrinkage.
