[ATM] Fusing Glass to Ceramic mirrors

[vorblesnak@peak.org]

This is a followup to the Fusing Glass to Ceramic thread I started a few
weeks ago.

It is noon on the 23rd and we just started the kiln. I sat and argued with
Susan about ramping speeds holds etc. and we finally compromised on some
settings. The concerns were ramping up slow enough to cushion the ceramic
base, and ramping down slow enough to cushion the Pyrex.

The program looks like this, all temps in degrees F ..

1. up at 200F/hr to 210
2. up at 100/hr to 800
3. up at 200/hr to 1800 hold 20 minutes
4. down at 100/hr to 1040 hold for 1 hour
5. down at 100/hr to 900 hold for 1 hour
6. down at 45 to 100 then off

Total program time should be around 34 to 36 hours. I don't know how fast
the kiln loses heat so that is an unknown. I will check it on Friday and
let you know.
