At the last century the ceramists firing porcelain did not have cones to
check the state of cooking=2E They used small objects called " fusible watch=
es
" ("montre fusible" in French) similar to the products to fire=2E They place=
d
these small objects laid out by groups in the kiln opposite the control
sight=2E When the ceramist wanted to know the state of firing, he took one o=
f
these objects with fire tongs through the small window of the control sight=
=2E
Thus he could control the state of transformation (body, glaze,
decoration=2E=2E=2E) and decide to continue or stop firing=2E

Subject: Cones: Why not =2E =2E =2E?
Thinking about the many discussions we have had about the fact that cones
serve to show energy absorption, whereas pyrometers show spot temperature
readings a (rare, I know!) thought occurred=2E
In firing to vitrification, we basically use cones that bend over when our
clay body (depending on thickness) should have vitrified=2E To me, this say=
s
that the cone has gone up to or just beyond its own vitrification point=2E =
If
this is indeed the case, why not make our own cones from the clay we are
firing?

A similar technique is used in salt firing with draw rings,
small rings of clay that can be fished out of the kiln
during the salting process to judge the thickness of the
application.
