7: Chasing the Bronze

After the ceramic shell has been removed from the casting the gates and pour cup are cut off with a grinder or arc - cutter. If the piece has several components they are now welded back together usually with TIG welder and on larger pieces with a MIG welder.
The sculpture is now ready to be chased. The Chasing process consists of several steps that progressively refine the sculpture until the desired surface texture and shape has been achieved.
First the welds are grounded down with an angle grinder or die grinder. Then the hand work begins. Hammers and chisels put back texture, like hair, over welded and ground down areas. Progressively finer and finer files are then used to refine the surface form and then the piece is finally sanded with abrasives to the desired finish.
