Do you mean the thickness of glass used to make dry plates?

Depending on the era I see "fifteen to an inch," "about 1/16 of an
inch," and 1.6mm. I think 1/16" and 1.6mm are more common later than
earlier ones but am not sure. There is about 1mm discrepancy between
1/15" and 1/16". Oh, I'm talking about 6.5x8.5 or smaller. Some larger
plates used thicker glass.
