In our last blog, we talked about handcrafting our Powder Coated and Colorized Rings. You can read that blog post here: https://coincrafters.net/blogs/news/how-we-make-our-colorized-coin-rings-part-1-of-2-hand-crafting-the-ring. Today, we're going to continue the process with adding color to the rings. Read on! We are going to make colorized coin rings!
They are available for sale here:
Powder coating is a coloring agent that is applied electrostatically as a dry powder over metals. It is then cured via heat until it flows and forms a hard layer. This coating is very resistant to damage.
Once I've created the ring (see part 1 of this blog), I place it onto a silicon plug with a copper conductor attached to it. The conductor also must touch the ring because I use an electrical charge to attract the powder coating to the metal of the ring.
I tape off any section that I don't want to powder coat with a high temperature tape. Although I'll be removing small portions of the coating later, its easier to begin by masking off larger areas.
Since I'll be using a an electrostatic gun attached to an air compressor, now is the perfect time to get everything set up and ready to go. I attach my gun and get my stand set up with the ring. I also preheat my oven. My powder coating flows at 450 degrees Fahrenheit.
Remember that conductor I attached to the silicon plug? It is going to touch the stand and ground the ring. As a result, when I spray the powder, it goes right to that ring. It doesn't take much to get a good and even covering.
Since the powder isn't adhered to the ring at this point, I need to gently transfer it to the oven and watch closely until the powder flows.
If I were to let it cure for the full 20 minutes here, it would be difficult to clean the coating off the raised surfaces of the silver that I carefully retained when I created the ring. As a result, I'm going to watch the powder flow, wait just one minute, and then take the ring out and let it cool.
At this point, the powder still isn't really hardened, but I use traditional jewelry filing techniques that I discussed in the last blog post to bring the raised areas of my silver coin through. The coating and color remains in the recessed areas.
I then continue curing the ring in the oven. This will make that coating really durable which is particularly important for jewelry items like rings that get a lot of abuse.
Finally, I cool the ring and finish polishing it using steel wool and a polishing cloth. Perfect!
