I wonder if contamination can cause the pyrometer to mis-read temps, like maybe it got coated with iron and doesn't work right.

I adjusted my kiln temperatures 50 degrees to compensate for this, but still had the same problems.

She said 50 degrees. So when she says she used 820 degrees is that really 820 or 870? Either way, reduction shouldn't really burn off at either of those temps so now I'm at a loss if you say her temp is really a known factor. I'm at 900 for reduction glass and any striking glass that can kiln strike and I think my kiln is running a tad lower. Nothing burns off for me now. At 960 I did have a problem with round beads and any raised stringer work, especially with Aurae. Before I figured out the problem I had done a whole set of non silver glass rounds with Aurae scroll work on them and when I took them out of the kiln the next day all the reduction was burned off the stringer work.
