[ATM] Annealing Schedules

[Richard]

I assure you that glass annealed according to schedules I have posted will
show no strain when examined between crossed polaroids.   However, since
this is off topic, I will not post further on the subject to the ATM list.

 Ther is a difference between what glass artist require in annealing -as in
Bullseye's charts- and a more optical anneal which is what telescope
mirrors demand.

For those who wish to get an approximation of the 
time needed, I invite  you to go to Bullseye glass's 
website where an annealing chart for their glass is 
posted as a downloadable PDF. That chart is only a 
departure point. "Your mileage may vary." 

Here are several sites to consider:
