1445°F, you look at theglassthrough a peephole andrealize
that the glass will need at least another 50° to fuse fully.
Change the target temperature to 1560° without having to
turn off the kiln to reprogram it.

etc. (Rate) (page 8) This appears in
Ramp-Hold programming for each segment. 1, 2, etc. are
segment numbers. Enter the rate of temperature change
for that segment. Rate is figured in degrees of temperature
change per hour. Example:
A temperature rise of 100° in two hours = 50° rate.
A temperature drop of 200° in one hour = 200° rate.
