Lost wax casting bronze, Lost wax casting technique
What's lost wax casting?
Lost wax casting technique is an ancient process, dating back at least 5000 years, used to obtain bronze objects.
All process steps of lost wax casting reflect this ancient method even if lost wax casting technique and raw stuff keep on changing.
Advantages of lost wax method
Although many artistic foundries use lost wax casting technique because highly accurate in faithfully reproducing sculptures details, this not means this technique does not require special skill and knowledge in this area. As a matter of fact lost wax casting is very sophisticated and it's a time-consuming process; this is the reason why many sculptors cooperate with BMN ARTE to realize their works relying on qualified staff.
Calc: first step of lost wax casting
First step of lost wax casting is the calc, a sort of imprint of the original model which will be produced by casting process of either metal or alloy chosen.
BMN ARTE produce the calc using either silicone or plaster. Producing moulds for statues is very important for the work success. Our artistic foundry has an excellent experience in this field.
WAX: the second step of lost wax casting
Second step consists in reproducing into wax the original model using previously produced calc and after various procedeures wax work is obtained.
During this same step we move on to wax retouching.
Wax retouching:: the third step of lost wax casting
Accurate retouching and finishing are needed to get a wax model closest to the original one with the purpose of obtaining an impeccable result. This is the step coming before lost wax casting.
Casting: fourth step of lost wax casting
During this phase casting prameters are set up once alloy or metal are ready to start casting , using moulding box. This phase has to be under careful supervision of an experienced master.
Once casting is over, moulds have to rest where they are for some days in order to avoid either sharp shrinkage or dangerous internal strain could compromise good result of casting and long bronze durability.
Chiseling: fifth step of lost wax casting
Using specific tools chiseler retouches work, removing possible chemical residues, highlighting details and refining contours to obtain a perfect work of art.
Bronze statues and all bronze artworks (as well as those produced with all alloys/metals) are then coated.
Coating: sixth step of lost wax casting
Out of casting bronze sculpture has eterogeneous look; as this stage a specialist applies patina produced with chemicals, giving to work the required colour and showing the unique features of the work iteself.
As to bronze objects, for instance, they usually are coated by a patina in various colours from a green tone to a brown slightly reddish shade; customers almost never choose bronze classic yellow gold colour.
