I can't wait to see a copy of this rewrite, especially the chapters on
glaze calculation and glaze software. Robin is quite renowned for
believing the whole Seger formula method of analysing glazes is not only
not helpful, but counterproductive. During the Q&A session at the end
of a panel that Ron Roy, John Baymore and I did at NCECA in Columbus,
Robin told us at great length of his belief that the whole system did
not work, and we should be able to make perfectly good glazes by mixing
together things we found in the local drugstore and our local creek
bank. Robin is one of the great glaze experts around today, but he even
describes himself as "an alchemist, not a chemist". Should be
interesting.

Hopper's update is available at barnes & noble (www.bn.com) for 30.00 and
change. I get specials from them in emails and until the 18th if your order
totals 40.00 you can use a code - snowman - and receive a 10.00 discount.
You enter the code word - snowman - when you are checking out and the
discount comes off your final price. I just ordered something small for a
christmas gift to get my order over 40.00. Was like getting the gift for
free. Love that bargain shopping :-)

Hello,
I remember it being a concern; what a lively panel :) Is there any other
book out there that explains glaze calculation just as well as the last
edition Rhodes wrote?

You can actually come up with an "interesting" glaze using 1/2 kaopectate
and 1/2 pepto :D Interesting ingredients in there.
Cheers,
Fabienne hanging on tight to her older edition

Yes, I have learned from my mistakes...
I can reproduce them exactly.

The writings of Daniel Rhodes were as much about Philosophy as they were =
about Technique, Process and Product.
I will be interested in learning if the quintessence of the Rhodian =
Philosophy is preserved in these editions. Recent comments of Paul =
Lewing suggest that there may be conflicts which need to be resolved if =
this project is to be a success. His reported discussion throws up =
issues related to the widespread use of computer assisted glaze =
calculation program and the need for safe and stable glazes which cannot =
be achieve by Alchemic Process.
Does anyone know for a fact what the Editorial Brief was to which Robin =
Hopper responded.

Hi Paul:
I would say that in terms of "developing" glazes the seger formula is
sometimes, but not always, the slower way to go. If we adhere strictly to
limit formulas, we will miss some very exciting results. To say that the
seger formula is not helpful and counterproductive for glaze "analysis" is
nonsense. I wonder if Robin thinks percentage analysis is a bogus system as
well. Without these two tools, how can a person get quantitative
information in their fired glazes? How do you know what the silica and
alumina values are when compared to the flux molecules? The answer I come
up with is: "Dunno"!
I've used empirical methods of blending different raw materials to make
glazes and I've taken the promising tests and analyzed them with the seger
formula and made some adjustments for durability if that's an issue,
expansion, and sometimes adjusted the silica/alumina ratio. My feeling is
that if you use everything at your disposal in order to gain a greater
understanding, one's productivity and knowledge will both increase. If
Robin thinks that the Seger system doesn't work, he doesn't have a good
understanding of how to use it to his or anyone else's advantage. I
totally disagree with him on this one. I guess that you have to examine
his definition of what is a "perfectly good" glaze. Perhaps to Robin, if
it looks good, it's OK. I like to know what my glazes look like on the
molecular level and I can't do that without using the seger formula,
current analyses, etc.
I'm not saying that everyone should be required to use any sort of tool or
method to calculate molecular structures of glazes. If empirical methods
make more sense and are something others would rather do I think that's the
way to go. You can always have your glazes tested or have someone else do
the molecular math. But to totally reject a very workable system that
gives valuable insights into the makeup of glazes is ridiculous.

I should have posted this info before - Robin asked me to write a
description of how I use calculation software. We can assume - perhaps -
that Robin has changed his mind somewhat on this subject.
I asked for - and got - letters from Robin and the publisher saying they
would print my conribution as I wrote it.
Will Robin learn to use calculation software? Not likely - and he is not alone.
I like the idea of others having to eat crow - and I have developed a taste
for it.
