Bronze Casting?

Question

I need some straight forward information about the bronze casting process real fast. I have searched EVRYWHERE and just can't seem to find any relevant information. Thanks

Answer 1

The lost wax process is only usually used for small, detailed sculptures or works, not huge great monuments!!

The manufacture of bronzes is highly skilled work, and a number of distinct casting processes may be employed, including lost-wax casting (and its modern-day spin-off ceramic shell casting), sandcasting and centrifugal casting. In the lost-wax casting method, the artist starts with a full-sized model of the sculpture, most often a clay model. A mold is made from the clay pattern; a wax is then cast from the mold. The wax is then invested in another kind of mold or shell, which is heated in a kiln until the wax runs out. The investment is then filled with molten bronze. Students of bronze casting will usually work in direct wax, where the model is made in wax. Should the casting process fail, the artwork will also be lost.

Another form of sculptural metal art to use bronze is ormolou. Ormolou is a finely cast soft bronze that is then gilded (coated with gold) which results in a matt gold finish. Ormolou was popularised in the 18th century in France and is typically found in such forms as wall sconces (wall mounted candle holders), inkstands, clocks and garnitures. Ormolou wares can be identified by their matt gold finish and clear ring when tapped, this indicating the underlying bronze as opposed to a cheaper metal alloy such as spelter or pewter.

sure, I set up a foundry so i can help. make a silicon mould of your sculpture, or whatever you want to cast, then youmake a wax positive. you then add runners and risers(also wax) this is where the bronze will flow into your sculptore. then you use a foam cup onto the runner and riser. then there is the whole process of dipping the wax into slurry then sand, from very fine(for detail ) to coarse (strength) then the wax is melted out in a drop kiln. what you have now is placed in sand, with just the cup sticking out. you con now pour. wait to cool, then break off the sand mould. After that you can finish the piece useing all types of machinery. you can also use chemicals to get different petina. this is very brief. If you need more detail you can mail me [e-mail]. The whole process is called the lost wax method. it is baced on the egyptian, a few thousand years old

Answer 3

The sculpture approach is called "Lost Wax" You first sculpt or mold your work in microctystalline wax. Next, attach the plumbing for the bronze pour. Then make your investment mold by covering the wax in a sand/silica/ceramic slurry. Wait for that to dry and do a "burn out" in a kiln to fire the investment mold and lose the wax (Lost Wax). Pack your investment mold in a sand box and pour your brozne. Wait for it to cool, bust the mold and cut off your plumbing. Then finish with a patina. I suggest you have professional foundry do it for you until you can be properly taught how to do it (not read how to do it, then try). If you want more info then search for lost wax. There are many good books and great artist that would be happy to show you their process.
