I have a sink that is 5 layers thick of 96. It had one bad side
so I have broken it up and want to try and fire it back into
the circle. I am using a metal ring with fiber paper lining.
I have it in the ring but now have no idea what firing schedule to use.
Any ideas? I think it should be held at longer at the soak stage and also annealed
longer than usual....but not sure. Would appreciate any thoughts.

Thank you,
Vicki

See Graham Stones's book Firing Schedules for Glass http://www.warmglass.org/books/books/126-fsg from Warmglass.com for information about glass project structure and related issues (page 33) and suggested firing schedules. It's well worth the cost of the book to avoid (hopefully) spoiled projects and time spent dithering about developing a firing schedule.

Also make sure you've lined your stainless ring with fiber blanket or fiber material that's at least 1/8" thick, not just fiber paper, which makes me think you've lined it with a product like Thinfire. You'll need a little more room to allow for expansion.

Actually I do use fiber blanket material...... I use Patty Gray's firing schedule
to fuse the sink so was wondering if I could use the same schedule and just
add time to the soak and annealing times?
