Thanks in advance! Norm! 8^o

The two have similar chemistries but are somewhat different
physically. Pioneer Kaolin is not as white burning as EPK, it is
not as consistent from batch to batch, and it tends to flash with
a greyish coloration. EPK is better in glazes because it tends
to gel (flocculate) the slurry. Pioneer is a little more plastic
in clay bodies. These clays come from two different companies,
one is a lot more consciencious toward the ceramic community
than the other, I won't say which.

Hi Tony,
The reason I was asking was because of your cone 6 matte glaze. I have
about 100 pounds of EPK that I would like to be able to use. Will EPK be
good to use??
Thanks for all your help and especially the time you put in on your Glaze
web pages. I love them!
Norm! 8^o

EPK is the only kaolin I use in glazes. It gels the glaze better
than anything I have seen. If you can get 20% or better EPK into
a glaze it often glides on with no drips into an even layer that will
stick and stay even on the densed bisque ware.
