Several weeks ago there was a discussion on Clayart about
reusing underfired cones. It is an interesting topic, so I
test-fired 015 self-supporting cones to find out if
underfired cones would still be accurate. I discovered that
they bend just a little sooner than fresh cones. I posted a
picture comparing refired cones with fresh cones in
Paragon's Kiln Pointers newsletter:
