Quick and dirty:
Garage between 950 and 1000, no higher.
Anneal at 1050, size of piece determines soak time.
1 to 1.5 hours per 1/2 inch of glass is my rule.
After your soak just shut it down and let it cool with
no ramp down.
If you are worried about strain point, which I am not
with borosilicate, ramp down to 950 and and hold for
10-15 minutes then shut it down and let it cool.
This works for me, good luck.
