Jewelry Kiln

This kiln is working, but has no active users, so we are in the process of learning its idiosyncrasies and making a proper doc.

T value = time until next step

Step	Set Temp (˚F)	T value	Check time	Check temp	Notes
1	80	15	10:33	75
2	300	15	10:48	295	213˚/15min = ~14˚/min
3	0	-121	11:03	265	it definitely works

Asked the kiln to try to ramp to 2k˚ in 15 minutes. The alarm relays are firing, but no alarm light or buzzer sounds, so we need to get one (or two).
