Beautiful Sculptures

A fine selection of cold cast bronze sculptures by Denise Murray currently at the gallery.   Cold Cast Bronze is another way to cast a bronze which doesn’t involve a foundry.  The pieces are first modelled in wax or clay. A plaster mould is taken from the finished sculpture.  From this plaster mould a “master” is cast in resin.   After the master is sanded and smoothed a silicon rubber mould is made.  Instead of the traditional bronze, cold cast bronze is in the form of a fine powder.  This is mixed with resin and painted into the silicon mould and allowed to catalyse.  The mould is then sealed and filled with resin. A sheet of lead is added to the final pour to add weight to the work. When the piece comes out of the mould it is sanded, the seams are filled with additional bronze resin and it is polished to bring the bronze to the surface.  It is then given a patina and a final polish. After a while, if the surface is dull it can be brought back by polishing with the finest steel wool (0000 grade).  An amazing process - but oh so worth it - this selection is just divine.
