Please do not think that I am questioning your expertise. I am only trying to help. I take it seriously when a customer is unhappy with our products.

Here are my stress test results using 1) Bullseye polarizing filters, 2) polarizing sunglasses alone, and 3) a combination of a Bullseye polarizing filter and sunglasses:

Have you contacted the glass manufacturer about testing their glass for stress?

Are you sure your pyrometer and its thermocouple are accurate? The analog pyrometers I've used have an adjustment screw that moves the needle in either direction. This can throw off the reading.

The temperature is lower in the collar than in the heated section of the Caldera. Compensate for that difference by programming the controller with a slightly higher temperature.

I wrote the "Annealing Glass Beads" instruction sheet that you posted above. My schedule was meant to be altered if necessary.

I'm sorry our customer service department was slow in responding to you.

Sincerely,
