Most foundries would cast the figures seperately and weld them back together after casting. This presents quite a few problems, not least the actual correct stance that the artist had in mind. For this reason the decision was made to mould and cast the figures in the exact stance the artist had set up in the wax models of the dancers. Both figures require casting as hollow bronzes, so a solid core investment has to be put into each figure, another tricky process. The calculation with all casting is to place the minimum amount of feeds or sprues to the wax patterns so as not to disturb too much surface detail. It’s a fine balance, not enough feeding to the right places and incomplete castings are the result.
