Interesting points on "casehardening" if the kiln is run for too long of=20
a straight stretch. That topic is also covered here, with diagrams:

Wow! Kilns don't usually live indoors, unless you are doing small boards?
This book (available in .pdf online)
<https://www.srs.fs.usda.gov/pubs/37440>
discusses kiln drying, chapter 13 should be informative.
Looks like you'd need to tend/readjust the gizmo twice a day
for a week.
The final step (highest temperature) kills off bugs and such... 180 Fahrenheit.
If you start with air-drying the kiln finishing might be quicker.

I've seen a pretty good explaination on the US FPL site, altho I don't
seem to have a bookmarked link; or, iirc, Hoadley's book has a section
as well...
