Casting class: my giant heart shaped ring

I love it! I had been searching for a ring just like this on Etsy but to no avail…so I made it myself!

Ta-da! My lovely new heart ring.

This was my final project for the jewelry casting class I’ve been taking at Jewel Envy here in Toronto. I posted previously about carving the wax model and the casting process. Here’s what happened in the last two classes.

Below are the ring pieces after dissolving the plaster mold in water. It’s nerve-wracking fishing the casting out of the murky water because you are just praying that the casting process worked ok, otherwise it would be back to square one and hours of carving another wax model. You can see that both the ring band and the heart piece were done in the same mold. They’re attached by “sprues”, which are tubes that allow the molten silver to flow into the mold.

Next, the casting gets tossed into warm “pickle” (an acidic bath) to clean it off, and then I sawed off the sprues:

Next it’s hours of grinding away the bumps and polishing the surface, starting with a metal file or grinder and then using emery paper, starting with the coarsest grit and repeating with ever-finer grits.

Next I soldered the ring band to the heart piece.

So then it’s more hours of sanding the surface to remove all the dirt and discolouration with emery paper, until finally it’s ready for a buffing with grey stone polishing compound and lastly rouge polishing compound.

I just love my one-of-a-kind ring!
