Hi All: Back to British Columbia from NCECA, Spring here is almost as
advanced as Charlotte, hard to compare, different plants.

I wanted to compliment John H. on his presentation at NCECA on glaze
stability. It was one of the most effective presentations that I saw.
Being a Clayart person, I already knew quite a bit about the subject,
for non Clayart people, it seemed to be a big eye opener. Almost all
the way home I heard people talking about it, saying they were going
home to put lemon slices on their pots! The BOOK that is to come next
year should also be a hit, I am looking forward to reading it Ron and
John.

June from B.C.

Thanks June and thanks to everyone on Clayart who has supported me in this
work over the last 3 years or so. I would never have embarked on this work
without your help and support. The response to my talk exceeded my wildest
expectations; the room was packed with over 500 people and nearly all of
them stayed for the enire presentation. Thursday afternoon through the end
of the conference I couldn't walk 20 feet without someone stopping me to ask
a question or thank me. Wow, what a high!

Although Louis introduced me with an attention-getting statement, I focused
entirely on the need to make functional pots that are durable-in-use and not
get embarrassed by one of our pots walking back into our studio in the hands
of an angry customer. I don't know the answers to the heath-related
questions Fabienne raises in her post. No one does. Except for lead and
cadmium, there are essentially no data that are relevant to that discussion.
On the other hand, if health problems are ever identified with leaching of
other glaze components we will have moved in the right direction by focusing
on craftsmanship and durability.

I only want to learn how to make glazes as durable as possible within the
framework of good aesthetic choice. I think I have learned how to do that
and have also figured out a way to present it without too much
"techno-speak". I also realize I upset a few people because I am taking
away their excuse for making shoddy glazes in the name of attractive
aesthetics. Too bad. I think I have demonstrated you can have attractive
AND durable glazes. I guess, said another way, I want our "Evolving Legacy"
(the conference theme) as functional potters to be one of making pots that
people treasure and pass from generation to generation instead of being one
of a generation of potters whose pots were relegated to the landfill because
we were sloppy, ill-informed craftsmen and craftswomen who made pots that
disappointed.

I also made one offer to the audience that I would like Clayart members to
be aware of. I want people to teach this subject to their students, but
there is a virtual dearth of information collected in any one spot to assist
with that task. I have decided to make available a fully scripted set (60+)
of 35mm slides that could be presented in about 3 classroom sessions. These
are exactly the slides I used plus another dozen or so that I didn't have
time to present. They will be accompanied by a full set of notes/words for
each slide. If you are interested in learning more about that, visit my web
site at

One last note. We had a long discussion on Clayart recently on the
desireability of giving recipes AND Seger unity formulas when we talk about
a glaze. I also want ceramics publications to do this and made a pitch for
that at the end of my talk. Your Letters to the Editor of both Ceramics
Monthly and Clay Times (or whatever journals are read in your country) could
be a big help in making this happen. They read and listen to the letters
they get. How about it??

Thanks again to everyone, John

Hi John,
I also attended your presentation (most of--missed the beginning), and was
so glad that I did. I tried to get the handout, but it seemed to have
disappeared. How -- web site, fax, snail mail, etc. can I get a copy? I
put this out on our list because there may be a few others who came up
short, also. Thanks in advance..

Hi Gail,

I'm afraid more than a few missed getting a handout. I said in my last note
that over 500 people attended my presentation. I brought 750 handouts.
Unfortunately, some were apparently taking them by the handful. At any
rate, I would be happy to send you and anyone else a copy. Send me your
snail mail address or fax number.

I have tried to write the charts into an acrobat file but, for some reason I
don't understand, Acrobat doesn't like the graphs. For those who did not
attend the lecture, unfortunately the handout is not self-explanatory. It
is in brief outline form and was just intended to jog peoples' memory and be
a place to put notes. The book, of course, will have all of this information
and much more.

Regards, John

Johns lecture was one of the best I have ever seen. He deseves a lot of
credit for the time, effort and expence he is spending to illuminate this
aspect of our craft.

I am proud to be associated with him.
