We’ve moved on to the next stage in making the large (2.2m) Speak to us of Freedom sculpture. This sculpture is one in the Gibran Series.
The mould that was made of the enlarged model has been delivered to the TALOS ART FOUNDRY near Andover in Hampshire and the long and complex process of taking a mould to a finished bronze begins.
The mould has arrived at the foundry and here it is being taken apart to be ready for the next stage.
The mould is in sections and the first stage is painting wax into each of the sections. In the pictures, you can see the thickness of the wax and that will be the thickness of the final bronze. Runners and risers are added to each section of the pattern. These make sure that the molten metal runs into every nook and cranny of the mould by making sure that the metal runs down to the bottom of every bit and runs up to the top of every bit. Without them, air will get trapped while the metal is still molten and would be very visible in the finished casting.
Here is one section of the mould being painted with molten wax. The wax is exactly where the bronze will end up!
So here is the end of the first step. The bottom 600mm section of the casting has been formed out of wax. The circular rods are braces to hold the wax sections in place.
We’ll show you the various steps as we go along, so follow the blog and you can follow the process!
