Yes, I have been thinking about this but pieces 4 mm + 4 mm both were guardian cut from the same sheet of glass and still, they are not completly flat (but definitly better than 4 mm gluardian + 6 mm pilkington).

Yes, we fuse 2 pieces:

900 x 300 x 4 + 900 x 300 x 6 (6 mm thick piece lays on 4 mm thick piece). Total is 10 mm. Both are float, 4mm - guardian, 6mm - pilkington.

Hello Brad,

After tests as per your recommendation, result is still the same - only 900x300x4 + 900x300x4 is better (almost flat). All pieces where we melt 6 mm thick glass plus 4 mm are bent.
Do you have any other idea whats wrong?

Thank you very much.

Will conduct tests and till the end of coming week let you know about the progress.
