I misprogrammed my kiln this morning so it will get to the observation stage when I have a meeting I can't miss. My back of the napkin estimate is that it should be around 1000F on the way up by the time I can get there to reprogram it. Should it be safe to hold there a few hours then continue up when I'll be able to look or should I anneal it down and then restart later?

I'm using System 96 and am draping 7 inch disks over SS mixing bowls. They're one layer with frit contour fused on them. I haven't draped like this before so I know I have a too long hold time programmed at temp. My intent was to look and skip the excess time once the drape was done.

Many thanks!

1000 is above the strain point. Once you are above the strain point, there is no harm in holding. Devit tends to happen quite a bit hotter.

Thanks Bert.

I ended up holding a few hours and then was able to watch the drape. Good thing too: it slumped much faster than my before-added-time expectation. Next time I'll drop the temp some.

Now to get through the impatient time before I can get a real look at the results.
