Here are some of the questions I get asked regularly at shows.
Q: What is bronze?
A: Bronze is an alloy of approximately 80% Copper and 20% tin
Q: How do you create a bronze from a clay sculpture?
A: The foundry create a rubber two part mold from your original piece. From this mold they create a wax replica which is then invested in a heat proof ceramic plaster. The wax is then melted out of the ceramic shell (hence the tern lost wax casting). Then the molten bronze is poured into the ceramic shell to create the bronze casting. For a large bird in flight, the original piece will be cut into several pieces and mold created from each piece. Later, all the pieces will be assembled back together, fettled and chased util no join is visible.
Q: Where did you get your cool hat?
A: The wonderful Mackenzie and George!
Q: How long does it take to make a piece.
A: On average it takes me around 3months to sculpt a new piece and it will be in the foundry being cast for around 6weeks.
Q: What is patination?
A: This is the tricky process of adding various chemical oxides to the surface of the bronze to create colouring effects. This is achieved by heating the surface of the bronze to approximately 600 degrees C and carefully adding diluted chemicals to the surface. This is an artform in itself.
Q: Do you know where we can get a coffee?
A: Up the hill and first right. Have a lovely day!
Q: Do you make these?
