However its beauty might be part of this story.

down to the 12th line of slides.
I use these pedestals and catchers for crystal glazes as well as runny
glazes. Of course you can make your own catcher on the wheel - you can
see it in any of the crystalline glazes books.
Some of the ^6 glazes I make are runny on purpose therefore I tell you
do not "fix" the glaze.
About calcining the clay- It will make things worse - you will have to
add CMC, besides using 20% calcined clay means about 22 raw clay- you
higher the alumina it will be less runny and probably less beautiful.

Readers:
I have been using this glaze for some time. I forget its source or the
name
but tends to run.
I believe someone earlier told me to use calcined Kaolin so I might give
that a try and see if it will stabilize better? For my cone
(9-10)reduc. Goes to subtle purples and cremes. Especially nice for
porcelain. any hints as to how to stop a nice glaze from the runs :-(

Fir those of you who might use this glaze on functional war - it is very
short of silica and will be affected by acidic foods - the expansion is
very high so I think it will craze - as do most glazes that are short of
silica.
Best not to use it where food will touch it.
