Hi All,
Hoping somebody with more techinical expertize can give me a clue here.
This is a very spcific problem but significant and serious. With only
one of all the underglazes I use I am having isolated cases of delayed
shivering only on the handle. So a pot sits on the store shelf and one
day it's good and the next it's not. So I definitely have a problem.
This is Duncan's Bright Green cover-coat. The reason I love it is that
it has a variagated coloring and this is truly a delight in the underglaze
world where flat uniformity gets to be a real drag. I have assumed that there
is an extra high clay content in this recipe that is giving me the more
interesting color job.
I am also assuming that it is the high claycontent that is causing the
fit problem on the handle where a tendency to this problem would, I am
also assuming, be greater because of the shape.
My questions:
Can I add something to the underglaze that might help?
What would I add to other underglazes in hopes that the more clay-y
recipe might give me a more interesting result?
Eleanora...big on assumptions here and low on information, I sure hope
somebody has some insight here to help me. I am basing lots of work on
this lovely stuff and not using it is out of the question.

Eleanora,
Try adding 5% (by weight of dry materials) of your glaze to the underglaze
colour and, if you are able to work this way, apply the green to your work
before bisque firing.
Regards
Denis

>Hi Eleanor,
I have problems with this color and brand of underglaze. The only thing
that has improved this is adding 2% of bentonite and stirring well to mix.
I am still having problems with this when my students use this color so I am
doing glaze tests on some Axner underglazes. So far I've found them to be
richer in color with more depth. The red has a strong red-iron color to it,
even at cone 10. Good luck,
