1. A method of processing glass, the method comprising: forming a flexible gel layer on a flexible glass sheet to create a glass-gel sheet, wherein the flexible glass sheet is not partially or fully inside the flexible gel layer but rather is located entirely alongside the flexible gel layer; rolling-up the glass-gel sheet such that the glass-gel sheet is in the form of a roll; and placing the roll in a dryer, and drying the flexible gel layer so as to convert it into a flexible aerogel layer and thereby change the glass-gel sheet into a glass-aerogel sheet, such that the glass-aerogel sheet is characterized by a minimum bending radius of less than 200 mm.
