Creation of a big silver ring for women
Big silver rings are an ideal gift idea if your spouse loves to wear imposing and fancy jewelry. Silver is easily patterned for a reasonable cost and a single large ring can easily replace multiple fine rings worn on multiple fingers.
The realization of this ring was made to measure on behalf of a client. Given the 3D shape of the wide top plate of the ring, it took us a lot of exchanges to properly define the design and dimensions desired by the latter. The ring consists of a rather large curved part, since it's about 3 cm long and almost 3 mm thick and has an adjustable ring that offers more convenience for its wearing.
The ring design imposed on us a manufacture by the lost wax process technique which we propose you to discover here in pictures.
It should be noted that most bulky rings that we offer in our shop are made by this process
Wax modeling for silver manufacture
The technique of the lost wax was obvious for this ring because of the large volume and shape of the top plate, making it difficult to shape by the conventional work of a silver-plated plate. I will present the different steps of modeling and then casting the ring image.
The first step is to cut a wax plate in which we will carve manually the upper shape of the ring following the photos and sketches of the design. We do the same for the ring of the carved ring from a piece of wax already having the shape of a ring.
View of the two wax pieces cut manually in the mass and assembled below.
When these two pieces are finished, they are assembled on the same base to make a master that will be used to make the mold in refractory plaster in which the molten silver will be poured.
We then cast refractory plaster in a container containing our master, solidifying, the plaster takes the shape of carved wax.
Once the plaster dry and solidified, the base of the master is removed from the mold, the wax pieces remaining trapped in the plaster. The conical shape obtained will help pour the liquid plaster into the mold. Wax pieces are evacuated by heating the mold to convert the wax into liquid, which then flows out of the mold by gravity.
We can then sink the silver into the mold. To do this, the mold is placed in a centrifuge and then silver 925 is melted in a compartment connected to the inlet of the mold. The startup of the centrifuge then allows the cash to flow into all the free spaces of the plaster mold.
We then recover our silver coins by destroying the mold. It remains to deburr and polish and solder the tray on the ring. Finishing and polishing are then carried out.
Here is the final result :
