I have a repair project for setting a small [10 x 7 mm] cloisonne
piece into a 14K cast ring. The enamel is set flush with the surface
of the ring and the sides of the ring [bezel?] are 2-3mm thick. All of
this is, I’m sure, is to protect the enamel. It came to me with the
damaged enamel piece set in what looked like epoxy. It had a
transparent honey color and softened with acetone.
I remade and replaced the enamel using Devcon 5 min epoxy. I have
been told that the enamel has since released from the ring. The ring
is worn daily. I believe that I thoroughly cleaned the cavity with
acetone before “setting” the enamel with epoxy. The sides of the
cavity were basically straight. I could grind in a little groove that
would act like a holding ridge.
I am reluctant to work the sides of the ring over the enamel for a
few reasons: 1] I don’t want to cause ANY stress in the enamel by
possible pressure of the metal. 2] I don’t want to trap the enamel so
that it would have to be sacrificed if any future repairs were
I have gone through the archives for adhesives and bonding agents. I
understand that the super glues are not that super because they react
with moisture and release over time. I have not found much specific
info on epoxy.
I believe the answer lies with the setting agent. What help can you
offer? Oh yes, If you have a wonderful, can’t live without it product,
will you also tell me where it was purchased?
I will be meeting with my customer on Feb. 13
Thank you in advance
