We understand that it is generally known that glass is easily leached in an alkaline environment. However, we have never compared them wrapped in paper and we do not know of any links or books that can answer your question.

Hiroki Nagai Thank you for your answer. It is a pity that no resources are available. But I will continue to investigate this issue anyway.

My two cents is that the poorer adhesion you suspect is due to plate-like or film-like sodium/potassium (hydroxy-?)carbonates that can easily flake off, reducing adhesion. Try scraping the surface nice and flat with a razor blade and sonicate for a minute or two - I suspect this would alleviate adhesion issues.

Academic rabbit hole below: Glass surface leaching is incredibly complex because any ionic transfer to (K+, Na+) or from the surface into the glass (H+, notably) begins to move all of the ions about through the glass. Local thermodynamics (activity) and charge neutrality conditions confound the problem dramatically. The works by Y Liang and FM Richter in the late 90s (diffusion in silicate melts I, II, others) show how tough modeling or predicting even rudimentary interdiffusion behavior can be.

The best books I've seen on the topic of observed surface leaching and surface preservation are from Sandra Davison but I no longer have access to these books so I can't point out anything specific.

There are some recent studies using absolute cutting-edge technology to understand the weathering of glass of a potential spent nuclear fuel storage medium. In particular, I recommend the work of Dr. Stephanie Gin. The 2018 work in Corrosion Science 'The aqueous corrosion of nuclear waste glasses revisited' is the best up-to-date overview that I know of and is probably more accessible than her more technical 2017 work.
