Dear Brian,
That is what I was thinking, in making these tests.
I went out from 2 simple categories: flux or not flux. so as to avoid a
glassy pool. But we know that materials can behave as flux or not depending
on what they are mixed with. Now what? By mixing the material in such a
high precent as 50%,there is a good chance we can see the dominating
propery of a material. By adding it to a glaze base, simple ones, we can
see again the dominating feature of the material with a little influence of
other basic materials. The materials, as you say like Magnesium, is quite
a bullly, and seems to behave in the same way in all of the tests. I used
the green glaze, just to add some color, and I can see in the tests, that
the materials also of course, influenced the shades of green produced.
I think this is an excellent learning tool.

Alisa,
Last year Susan, a clayart lurker, from Canada wrote to me......
"I do obnoxious pieces that need an obnoxious glaze and I cant seem
to find one."
There is no doubt that a lot of materials that we use exhibit
extemely "obnoxious bullying" when used beyond what potters consider
"normal" volumes.
Zinc Oxide, bone Ash, and titanium oxide to mention only three.
This week Erik from Mudfire pottery centre in Atlanta
http://www.mudfire.com has invited me to teach my glaze texture
workshop there in June. It is quite a coincidence that this happened
during our discussion here and I look forward to visiting a new (for
me) part of the USA.

I am glad to hear that you are invited to do your workshop in Atlanta. I
wonder if it really is a coincidence, or maybe the Clayart discussions
perked Erik's interest as well? Good for you and happy should be the
participants of your workshop. I hope that could be me one day!
I will make some experiments with Bone Ash, Titanium Diox. and Zinc next
time and we can go from there.
Regards from Alisa
