Bending/Slumping direction of Bullseye Glass

Postby koerner » Thu Feb 28, 2019 2:20 pm

Hi-

From what I understand from a webinar, glass has a "north south" meaning is will always bend/slump 1 direction first. I believe Bullseye bends parallel to the ripple edge of the sheet, so if a sheet is supported in the center, the ripple edges will fall first then the perpendicular cut edge. Is that correct?

If we are working with 6mm testa, is the ripple edge the long 48" side of the sheet?

Thanks.

I have never heard that before. I think that the longer dimension might slump before the shorter dimension, but glass does not have a grain like wood or paper.

The Tekta does not have a rolled edge, it is cut straight all around. I agree with Mary Kay, the glass will slump 1st where it is heaviest and or at the largest area, because of gravity.
