Default A Simple, Practical Control System for Ceramic Kilns

Free booklet tells how combining "obsolete" controls provides equally good
results at a fraction of the cost of "high tech" solutions.

Happiness and success in kiln firing means consistently achieving good
results from low cost, easy to use equipment that operates reliably and
efficiently. Too good to be true? Not at all! The key to that kind of
happiness has been commonly available for years.

The KilnSitter® was invented in the 1950’s by Wilfred P Dawson, a theater
film projectionist whose wife was a ceramics artist. Thousands of these
units have been used over the past half-century, in all sorts of settings
and with consistently good results. The KilnSitter uses a special
pyrometric cone to regulate firings, much as a person would mind their kiln
manually. When the cone bends, the firing is considered complete and the
control trips the kiln off. Nothing could be simpler. Over the years this
ingenious little device has saved people millions of hours of kiln-sitting.

The KilnSitter does not regulate the early stages of kiln firing however.
That was a problem since in order to get to very high temperatures,
electric kilns have lots of heating capacity, and are capable of drastic
temperature rises when beginning from room temperature. FireRight provided
a solution for this problem many years ago with simple controllers designed
to regulate the turn-up process. Today’s implementation is called the
“AutoMate II Automatic Kiln Switch.” Used in combination, the KilnSitter
and the AutoMate II provide a completely automated solution, proven through
years of experience, and at a fraction of the cost of programmable digital
controls being offered today.

Warner Instruments has manufactured controls for ceramics and pottery kilns
since 1976, under the KilnTroller and FireRight brand names. The booklet is
