Woodblock printing had been known in China for centuries. It was innovations in type casting that made for Gutenberg's breakthrough of commercially printing. [1] Although using matrices was a technique known well before his time, Johannes Gutenberg adapted their use to a conveniently adjustable hand mould, enabling one to easily and accurately cast identical multiple instances of any character.
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots .
The Futurist movement was striving to portray speed and forceful dynamism in their art. Boccioni, though trained as a painter, began sculpting in 1912. He exclaimed that "these days I am obsessed by sculpture! I believe I have glimpsed a complete renovation of that mummified art." [2] The following year Boccioni completed the sculpture.
Continuous casting is used due to the lower costs associated with continuous production of a standard product, and also increased quality of the final product. Metals such as steel, copper, aluminum and lead are continuously cast, with steel being the metal with the greatest tonnages cast using this method.
The bronze Gloucester candlestick and the brass font of 1108–17 now in Liège are superb examples, very different in style, of metal casting, the former highly intricate and energetic, drawing on manuscript painting, while the font shows the Mosan style at its most classical and majestic.
Once the mold is reassembled, at its most simple the casting material is poured into the void and left to set. Traditionally, molten bronze is used as the casting material, but modern alternatives include resin. When the cast sculpture has cooled or cured, the mold is again separated to release it and reassembled ready to cast the next copy.
The Droste effect (Dutch pronunciation:), known in art as an example of mise en abyme, is the effect of a picture recursively appearing within itself, in a place where a similar picture would realistically be expected to appear. This produces a loop which in theory could go on forever, but in practice only continues as far as the image's ...
Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
