Visual art forms that include sculptures can be traced back eons of years ago. You can find sculptures out of concrete as bas relief on buildings, and miniatures made from ceramic or ivory. Marble is probably the most popular medium for sculpture, though other media can be used for it too, like bronze.
Bronze is amongst the sculpture media that remains in contemporary art. The mix of copper and tin, bronze is considered the strongest metal alloys which can be used in any application. Even when it corrodes, this shiny red-gold alloy becomes a stunning and even stronger blue-green material. Bronze may or may not be mixed in sculpture with different media like glass, plastic, or steel.
There are lots of sculptures that follow the norm of several art genres. Modern and postmodern sculptures are interesting in their impressive use of forms and color. Contemporary art may or may not be shaped; irregular figures are considered the most recognizable properties of several artworks completed in recent decades.
On the other hand, art aficionados could perhaps admire near-photographic images reminiscent of classical and renaissance sculptures. This is perhaps why a number of people are blown away by bronze sculpture. Catching exact interpretation of life through bronze is a feat for people with astute minds and creative hands.
Bronze sculptures are made with the lost wax casting technique. Which means that the sculptor needs to first produce a mould of the image; this takes exceptional care to make the image lifelike afterwards. After that, molten bronze is carefully poured in the mould, where it is left to cool. Whenever you go to a shop with bronze sculpture for sale, it is likely that the sculptures are forged this way.
Dark grey or blue-green discoloration on bronze is called patina; not like rust, patina functions as a protective covering over the bronze to prevent further corrosion. French bronze sculptures with patina are usually stronger than freshly made red-gold bronze. Several sculptures intentionally put patina on the sculpture by inducing an effect using ammonium sulphide, liver of sulphur, or ferric nitrate. A particular light green patina identified as verdigris is caused by chlorides, sulphides, and carbonates.
Some sculptures are finished with ormolu rather than corrosive substances. Ormolu is a mixture of ground gold and soft bronze to give the bronze sculpture a gold-like presence, leaving the bronze's strength intact. Ormolu finishing is featured in French sculptures; it is notably used in timepieces, fancy containers, and candlesticks. For additional information, see BronzeSculpture.com.
