Did anyone else get a picture of a bicycle race instead of a pot when going to this link?

I have been experimenting with a very simple beading glaze, and getting fun
and funky pieces with reticulated crackles when I put it over a dark cobalt
glaze. Last firing I did a few test pieces with temmoku and the beading
glaze over. Totally different results! The temmy looks like what I believe
is called tea dusting. You can take a look at:

Is this tea dust?
I was disappointed when I unloaded them, thinking I must have messed up the
application of the beading glaze, but on second look, I really like it a lot
:-)

Add jpg to the link thusly,=20

http://cresswells.com/pots/teadust.jpg

if you want to take a look.

From my understanding, teadust and tammoku glazes are very closely
related. The teadust look of your piece is similar to what I have seen.
I have seen the light color floating in a dark background. Daly
mentions teadust tests in his glaze book if I remember rightly. I often
do not.

Well, I get the digest form of the list, so did not see my post, and that I
had fubar'd the URL that I sent, but a kind soul sent me a note off list,
and I sent a corrected url almost immediately to the list, but not soon
enough, or it got lost or what ever... my apologies,
here is the correct url:

Yes the glaze has the teadust effect though I wouldn't see it as a
traditional teadust.

Essentially teadusts come about from the development of ferro mangnesium
silicate crystals in the base glaze ie on a black backgound. These crystals
are yellow/green. In the traditional case the magnesium was probably present
in a basic rock that was ground to make the glaze. In my own case adding 10%
of talc to a good tenmoku would get a similar result. Of course you need
reduction and the slower the cooling the better they crystal development.

I was talking about traditional teadusts but I am very happy that you are
able to get a similar glaze and effect in oxidation.

I haven't looked at the chemistry of this in ages but I did think that the
green in the crystals required the iron to be reduced before the crystals
formed. Quite willing to admit this is pure memory at this stage and happy
to be corrected

----- The original under glaze was a black and it gave the beading glaze a
blue tinge- it had to come from the under glaze. Perhaps the iron(usually
8-11%) in the tenmoku underglaze acted as a flux and instead of beading, it
behaved more fluidly and was more like the tenmoku.

What do you think?
