Clear and transparent resin filling, beginning
of or advanced yellowing. The plated glass
compound still has a dark, shining aspect.
The whitish “micro-bubbling” is becoming denser.
Due to the yellowing of the material, the bubbles
can have a brown-ochre colour; under reflected
light the areas can also look “milky”. The adhesion
is beginning to weaken in these parts, but it remains
very strong on the whole.
