Paul’s chart is for annealing only. You aren’t going to be fusing or firepolishing at the annealing temperatures. I think Paul misunderstood the information you were looking for.

Go to the bullseye site and find the chart named “Basic Firing Schedules for Bullseye Glass 2020”. If you look there you will see the tac-fuse/fire-polish is around 1400*f (760c).
