I was please to see that the temperature lags very slowly in the acrylic compared to the other temperature sensor. I'm confident that I can follow the annealing chart very closely. I also wanted to arrange the two hold times ( for the normalizing run) so that they occur in the early morning so I can sleep ! I need to be actively monitoring the cool down periods.</DIV><DIV> </DIV><DIV>Brian</DIV><DIV> </DIV><DIV><BR>---
