104 annealing

I have not worked with 104 coe glass in a while and need to on a certain project. If I remember correctly it anneals around 950. What temps do you anneal 104 at.

I go 950 to play it safe...

I think anywhere between 940 and 960 is safe. I "deep soak" my re-pull murrni nibs at 1150 for at least 1 hour to get a deep heat into them so when they get pulled outta the kiln to re-heat and re-pull, they're nice and toasty. I set them close to the door so they're easy to pull out, so maybe they're not quite 1150, but anything hotter than this and you'll be pushing them close to slumping...
