Very strange. Glass should be stored on edge so even leaking water should
not collect between sheets.
Quality glass should not have a formula that results in alkaline
breakdown.

hi, during storage of flat glasses they undergo some defects because of
producing some alkaline solutions. can somebody tell me how can I solve
this problem?
