Lost wax hood and cast
Lost wax hood and cast
We continue to describe the wonderful technique of lost wax, a technique that creates wonderful bronze sculptures.
The third step to make a wonderful bronze statue is to arm with brick and iron the soutane, creating the so-called hood that will make the structure more resistant when cast bronze cast.
This step will represent, in fact, the penultimate step in the realization of our work in bronze.
The brick hood is armed through a tie made from iron plates that make the hood even more elastic.
In fact, when the molten bronze will collapse into the space left behind by the lost wax, it will cause a considerable thermal shock that could damage or even crack the hood itself.
Our foundry studies and applies from over a century, the best methods to otter an elastic and resistant hood that can allow a safety flow to give birth to a bronze sculpture already very close to the desired result.
Hood, robe and soul are placed at the lowest point of the furnace, where it will run off the bronze.
Then We proceed with the most important operation: bronze casting.
If casting is not performed with surgical precision, the risk is to vanish all the work done so far.
A single air bubble, a crack in the tannery or the soul can cause the slip of the bronze out of the tuna, giving rise, at best, protruding or unexpected holes in the statue we are sculpting.
Therefore casting must take place in a sufficiently long time.
The foundry masters of our foundry control casting instant by instant, controlling the bronze flow with unique mastery. This allows us to be leader in wasted cast fusion, so that some artists, such as Paladino, prefer our foundry to make their sculptures.
Slowly, slowly, slowly; The bronze flows, touching the clay of the soul and tonaca, cools.
Bronze should do not break but forge slowly without leaving.
Another disadvantage, however, that can occur during casting may be the early cooling of bronze which may rise lumps in the bronze sculpture itself. Our bakery masters are skillfully able to avoid this problem by adjusting the flow of molten bronze by beginning to speed up casting when molten bronze begins to penetrate more in the hobs slightly cooling. Increase the flow of cast also heats the farthest liquid bronze, avoiding the formation of these bronze lumps.Too slow, too fast, casting is an art in the art, something that only experience can made perfect.
Thus the last but two and the penultimate stages of bronze sculpture end:
