Whether the starting point is a hand-made drawing or a computer modeling, our tailor-made service is capable to materialize any project, any request of the client.
In certain cases, a nice pencil drawing enables to better appreciate the proportions and details.
To create the “chef modèle”, the traditional way is a wooden sculpture, but it is not the only option today. It is possible to obtain, depending on the forms and delays, a 3D impression in resin, or a model directly milled in metal in our workshop.
Settled in Touraine, the foundry still uses a ladle.
As such, it is possible to work on small series without an intensive implementation.
The usage of resin sand is essential and offers a great quality starting point to the entire production, as its subtlety enables to closely reproduce details.
It is the art of bringing back to life every detail of the pattern.
By ingeniously using small light or mat chasing scissors (typical of each era), the chiseller redefines the edges and asserts the patterns.
The quality of this work is essential for the aspect and accuracy of the bronze to be consistent with the model.
It is the process of assembling with heat (weld, braze..) or cold (rivet, threading, inserting…) different subcomponents of an item.
Indeed, the complexity of each model requires to melt distinctively all the parts of a same set for the casting to be done.
The bronze assembler will come once the items are carved, and will adjust them together giving the spectator the impression of a unified and consolidated whole.
Operation whose importance is unknown, it is however crucial.
The polisher prepares each surface of each piece according to the desired final finish.
He usually begins with the abrasive belt, then continues with braided cotton wheels or boiled wool to complete his work. All the subtlety is to erase the traces of tools without overwriting the finesse of the patterns, the carving work and the correctness of the adjustments.
Completion and burnishing
The passage in the treatment baths is the last phase but not the least. Several meticulous and delicate stages are necessary to deposit silver, nickel, chrome … or gold on the parts.
M.E. Dupont has developed a rare skill of mercury nitrate gilding, commonly named “façon Ormolu”. This process enables to obtain a color equivalent to the usage of amalgam, without any risk to the environment or one’s health.
The part is plunged in a bath of gold, then in a mercury nitrate solution to create a shaded mercury-aspect layer.
The usage of flames allows the mercury to evaporate, creating golden nitrate with a mat aspect. Then comes the work of the agate stone, also called burnishing, which consists in hand-hardening all the prominent parts. We then obtain the true mat and bright of these antique parts.
Two sets of services are proposed: conservation and restoration.
Conservation consists in cleaning and making the item safe for usage, without touching the completion of the metal, or its integrity. Dealing with ancient heritage, objects belonging to private owners or museums, and giving it a new life without changing its essence is the exact goal of conservation.
We are also able to replenish an incomplete item, to repair a damaged one, to redo a decor: this is restoration work.
