Amazing things can be done to polish, grind, cut and carve glass and usually with great success. Paperweights are a good example. However, to draw an absurd parallel, if you have a cup full of water and merely stick a pin into it, it breaks the surface tension and spills over a bit. By reducing the outer surface in grinding or polishing heavily, you conceivably may be removing the strengthening layer rendering the piece vulnerable to the underlying strain which results in the glass relieving itself by cracking.

Perhaps you can get a scientist to properly convey this..it’s real and worthwhile. There is a violinist in Indiana…was with philharmonic…. collects weights and is an expert polisher….he did one of mine… amazing job… months later I walk into room and see it broken. He repaired and it’s now fine… glass is mysterious.
