I have read that once a crack appears that it can never be
repaired. Can you elaborate on your efforts/successes with
I often found that on the back side of the plate, the counter enamel
was thinner and the crack formed on the front in that same area.
This was especially true of when I used liquid counter enamel, more
difficult to get it all brushed on evenly. I would put more counter
enamel in that area and then refire. It usually healed the crack and
it didn’t come back. I’ve had students drop enameled pieces and
crack them, did the same proceedure and it worked. I have had some
cloisonne crack (truth is I dropped it on cement) and chipped off a
corner. Sometimes with all transparents, it’s more difficult to get
the crack to go away but usually with more counter enamel in that
area the problem is cured.
