Abstract
Provided herein is a method for producing glass-ceramic sheets. The method includes texturing at least one surface of a first glass sheet, and stacking the first glass sheet and a second glass sheet. The first glass sheet and the second glass sheet are stacked so that the textured surface of the first glass sheet contacts a surface of the second glass sheet. The first and second glass sheets are cerammed. After cooling, the cerammed first and second glass sheets are separated. Also provided is a pre-form for producing glass-ceramic sheets. The pre-form includes a first glass sheet having a textured surface, and a second glass sheet contacting the first glass sheet. The textured surface of the first glass sheet is in contact with a surface of the second glass sheet.
