Abstract:
A method includes heating a glass preform having a plurality of glass layers and drawing the glass preform in a distal direction to form a drawn glass sheet extending distally from the glass preform and having the plurality of glass layers. The drawn glass sheet is thinner than the glass preform. The drawn glass sheet can be rolled onto a collection spool. At least a portion of a glass layer can be removed from the drawn glass sheet. An exemplary glass sheet includes a first glass layer, a second glass layer adjacent to the first glass layer, and a thickness of at most about 0.1 mm. An exemplary ion exchanged glass sheet includes a thickness of at most about 0.1 mm and a surface layer that is under a compressive stress and extends into an interior of the glass sheet to a depth of layer.
