I have found only a few people that do cloisonne repair and they are backed up for a year and get $300 for each piece. Has anyone been able to use other methods / materials at home and get decent results? I have one with a brass finish and one with a chrome finish. Could I chrome and brass plate the parts then use some type of translucent paint? These are not very intricate.
I'm sure you've researched this but if not Mr. Google provided this link: https://homesteady.com/12460334/how-to-restore-chinese-cloisonne Not sure if it even applies but it might be helpful, or not.
You need a oven capable of 1200 degrees. A jewelry "burn out" oven would work. You can get the colors from a wholesale jewelry supplier. They are like little crystals that melt into the area you want
I have no idea if it would work or not, but candy paints are basically translucent coloured and would work in the same way as glass, or?
I learned how to bake enamel in middle school. Depending on your materials might be able to do it translucent. No reason why candy paint wouldnt work, do some experimenting and youre still a long ways from 300 per piece. Start with a good chromed surface or polished surface.
What about a tinted resin (2 part?) to pour into the areas you want, then sand / buff that down level with the metal's surface?
As Gnichols said, the epoxy with a drop of paint in it works. I have used this method, and it works well. If the piece or section you are working on is reasonably flat, & if you use the epoxy which takes 24 hours to set, it will flow flat, and end up with a gloss finish. You fill up the indents with a small screwdriver, dipped in the wet goop, a drop at a time. A warm room or shed helps it flow. The enamel they use for painting plastic models is good, and available in a million colours. Experiment first on some scrap stuff, sometimes you only need a pinhead of paint in a few drops of epoxy. The only drawback I see is that epoxy goes soft at around 90 degrees C . (you can do the conversion to F)
I wouldn't hesitate to go with candy paint(s) or the tinted epoxy. I've done that to fill in missing chips of color in emblems. They look okay standing next to the car. I recently had a couple of chrome pieces that I wanted to have a brass look. I shot a light amount of candy brown, wiped the high relief areas with a semi-dry solvent rag, and then overcoated it all with candy yellow. This gets a clear gloss or clear flat topcoat depending on the effect I'm going for. It's not exactly the same as the cloisonne work but it's all related.
I just did a repair to an enamel sink using epoxy and adding a touch of the tint used to change or modify paint colours. I got the tint from the local paint store. The epoxy I used for this repair, was 5 minute, quick setting epoxy, and the repair worked better than I expected. If a person was going to actually bake enamel for a true cloisonné project, I have used an oven used for baking pottery. If you live in a populated area, you might be able to find a hobby store that will have the equipment, or will give you a lead to a hobbiest that does have an oven. Bob
Product available from jewellery suppliers called Ceramit, works like 2 part epoxy but harder, bake in a regular oven at 350 if I remember correctly. Lots of colours
