cone bending

Frederich, Tim on tue 10 jul 01


Hello,
The question was asked about the cone bending after the kiln is shut off. A
cone may bend a few more angular degrees after the kiln is shut off. This
will depend on the type of kiln, the amount of insulation and how fast the
kiln starts to cool. A few angular degrees may only equal 1 or 2 degrees in
actual temperature change. For most applications this change is
insignificant and will not have any bearing on the amount of heatwork that
is achieved. Most kilns start to cool fast enough so that deformation of
the cone stops almost at once. I hope this answers most of the questions.

Best regards,

One of the problems with fast firing is the cones go down real fast - like
some times all at the same time.

I watch the cone drop as the kiln is soaking - more even firing and I can
stop the cone anywhere I want.
