Garden sculptures "Rabbit Quartet", bronze

An alloy of copper with other metals (especially with tin) used since ancient times.

When casting bronze, the artist usually applies the lost-wax technique which is dating back more than 5000 years. It's the best, but also the most complex method of producing sculptures.

First, the artist forms a model of his sculpture. It is embedded in a liquid silicone rubber mass. Once the material has solidified, the model is cut out. The liquid wax is poured into the negative mould. After cooling down, the wax cast is removed from the mould, provided with sprues and dipped into ceramic mass. The ceramic mass is hardened in a kiln, whereby the wax flows out (lost mould).

Now we finally have the negative form, into which the 1400° C hot molten bronze is poured. After the bronze had cooled down, the ceramic shell is broken off and the sculpture is revealed.

Now the sprues are removed, the surfaces are polished, patinated and numbered by the artist himself or, to his specifications, by a specialist. Thus, each casting becomes an original work.

For lower-quality bronze castings, the sand casting method is often used which, however, does not achieve the results of a more complex lost-wax technique in terms of surface characteristics and quality.
