Let me preempt a bunch of replies from the enamelist community: Just
refer to stuff like Ceramit as “resin inlay”, a lot of the vitreous
enamel purists take big exception to using “enamel” for referring to
the cold resins.
That said: Even with vitreous enamel, it’s not unheard of for a cell
to pop like that on a ring. The problem with wedding bands, is that
many people will keep them on even in the shower and the bath, and
it doesn’t take much of a thermal shift to get that cell pop effect
if there is the tiniest flaw in the resin or enamel adhesion.
I’d say examine the piece. If you don’t see any sign of voids or lack
of adhesion in the other cells, just clean out that specific cell and
re-do it. You might need to add a little undercut to the base of the
cell walls to give the resin a “key” to lock into.
