Iron Rings, Figure 1

Two iron closed rings waiting for the third to complete an iron Borromean rings sculpture
The techniques for casting iron are somewhat different from those for casting bronze. The form to be cast can be made in wax or clay (plastilene), and is embedded in a mold made of fine sand treated with a special hardening resin. An open-face mold was used to create a sculpture on one side of a piece of iron, and also a closed mold with two parts to create solid iron rings. Three rings were attempted in order to make the Borromean rings, but the third ring was made split for assembling the group. Problems with the casting of that split ring were solved by extensive welding.
