Complete failure? It probably won't but it will continue to look worse and worse. The "artifact" or the fern is the result of inadequate exposure to the UV source. The ring may well indicate how flat the two surfaces were at the time of joining them. Newton rings sugggest very close fits.
During the period when I was trying to use UV before abandoning it was that the light source needs to be warmed up. We finallly kept our light under a cardboard box running all day. If you don't warm them up, the filament develops a coating that interfers with the bonding.

I've taken them apart using Methyl Chloride ( Toxic) but it's a lot faster to bite the bullet and saw them, resurfacing everything and this time doing it in Hxtal.
Where are we going and why am I in this basket?
