Answer 2

Hey !!

When amorphous solid (glass) are heated and cooled slowly, they acquire crystallinity at same temperature. Glass objects of ancient monuments, over a period of years, are exposed to sunlight and cooled during night times, which has resulted in the crystallization of the glass object which imparts milky colour to the ancient monuments.
