Gerald, I think the main conclusion was that reduction was the problem, however if you were to couple a long garage segment with your 5 hour anneal you would likely see enough COE shift to cause problems. There was a long article on chrome and sparkle colors in one either glassline or the flow that gave much more specific information based on experimental data but I can't find it now.

Larry: I'm pretty sure that boro manufacturers recommend 1 hour at annealing temperature for every 0.25 inches of piece thickness. I am also pretty sure this is overkill to cover against liability on "adult novelty items" and so forth, though that last is not based on any facts and is merely my opinion.
