Hi Ron,
Thank you for the invitation for further discussion. Very quickly I am =
realizing
the disadvantages of communicating complex issues in a few short sentences =
via
internet.
I taught glaze chemistry at college level and I have used the same arguments=
as
you did in your post, so you are preaching to the converted. I have used
Hyperglaze, Tony's program and now exclusively John Eden's glaze calculation
program. You and I are in agreement :
=22 I would be very surprised if you can make anything in clay worth a look,
without you having to follow some rules: be it clay preparation, firing
schedule, cooling and so on.
I am not quite sure what it is that you are trying to say. Perhaps you are
referring exclusively to unity formula limits ? They are guide lines not =
limits
as such. Kind of like learning perspective drawing (definite rules there) =
when
your interest is to free draw. It gives you a frame work to be able to =
visualize
a glaze before mixing (an educated guess at best).=22
So you and I are saying the same thing here.
You make a good point though, I should know better then to make a blanket
statement
about glazes being in or out of balance and their appearance without =
qualifying
that statement. This was based on my experience and it is only an opinion =
not a
fact. At low temp. and medium temp. if one excludes lead, barium, and zinc( =
zinc
is not toxic but because of its strong influence on most colours), what do =
you
have left for fluxes: Na2O K2O, LiO, for strong fluxes (with positive =

on colour) and Boron. You know the problem with Boron for glaze =
calculations.
My point is that one need not obsess over calculations which by the way =

eutectics, variations in materials (we use purely theoretical analyses for =
glaze
ingredients), glaze body interaction, atmosphere, rate of temperature
increase/decrease, colour development, to name a few.

Paul: Could you please tell us more about the John Eden's glaze calculation
program. Where ? Why? and What?....thank you MB

A couple of people have asked me off-list, whether we really call
those slow moving pieces "shelf huggers" in the UK. I have no
idea. It is just what _I_ call them. I only know they are called
"shop carers" in German.
Sincerely
Janet Kaiser - amused and annoyed by the antics of the public in
this hot weather... Being kept awake until 3 a.m. by carousing on
the beach and then woken up just before 6 a.m. by loud music, car
doors slamming, shouting at a dog, a dog barking... When I stuck
my head out of the window to protest, the woman of the happy
family told me, "We are on our holidays!" Oh, yes... And this is
so true it hurts....
The 10 Commandments of Email
1) Thou shalt include a clear and specific subject line.
2) Thou shalt edit any quoted text down to the minimum thou
needest.
3) Thou shalt read thine own message thrice before thou sendest
it.
4) Thou shalt ponder how thy recipient might react to thy
message.
5) Thou shalt check thy spelling and thy grammar.
6) Thou shalt not curse, flame, spam or USE ALL CAPS.
7) Thou shalt not forward any chain letter.
8) Thou shalt not use e-mail for any illegal or unethical
purpose.
9) Thou shalt not rely on the privacy of e-mail, especially from
work.
10) When in doubt, save thy message overnight and reread it in
the light of
the dawn.
But in case you thought that was all, please peruse the following
as well:
STUFF TO REMEMBER WHEN E-MAILING:
1. Big companies don't do business via chain letters. Bill
Gates is not
giving you $1000, and Disney is not giving you a free vacation.
There is no
baby-food company issuing class-action checks. Proctor and
Gamble is not
part of a satanic cult or scheme, and its logo is not satanic.
MTV will not
give you backstage passes if you forward something to the most
people. The
Gap is not giving away free clothes. You can relax; there is no
need to
pass it on "just in case it's true."
2. There is no kidney-theft ring in New Orleans. No one is
waking up in a
bathtub full of ice, even if a friend of a friend swears it
happened to
their cousin. If you are hell-bent on believing the kidney-theft
ring
stories, see
www.urbanlegends.com/medical/organ.theft/organ_theft_unos.html.
And I quote: "The National Kidney Foundation has repeatedly
issued requests
for actual victims of organ thieves to come forward and tell
their
stories." None have. That's "none" as in "zero." Not even your
friend's
cousin.
3. Neiman Marcus doesn't really sell a $200 cookie recipe. And
even if
they do, we all have it. And even if you don't, you can get a
copy at
www.bl.net/forwards/cookie.html. Then, if you make the recipe,
decide the
cookies are that awesome, feel free to pass the recipe on.
4. If the latest NASA rocket disaster(s) DID contain plutonium
that went to
particulate over the eastern seaboard, do you REALLY think this
information
would reach the public via an AOL chain letter?
5. There is no "Good Times" virus. In fact, you should never,
ever, ever
forward any email containing any virus warning unless you first
confirm that
an actual site of an actual company that actually deals with
viruses. Try
www.norton.com. And even then, don't forward it. We don't care.
And you
cannot get a virus from a flashing IM or email, you have to
download it ....
ya know, like, a FILE!
6. There is no gang initiation plot to murder any motorist who
flashes
headlights at another car driving at night without lights.
7. If you're using Outlook, IE, or Netscape to write email, turn
off the
"HTML encoding." Those of us on Unix shells can't read it,
anddon't care
enough to save the attachment and then view it with a web browser
since
you're probably forwarding us a copy of the Neiman Marcus Cookie
Recipe anyway.
8. If you still absolutely MUST forward that 10th-generation
message from a
friend, at least have the decency to trim the eight miles of
headers showing
everyone else who's received it over the last 6 months. It sure
wouldn't
hurt to get rid of all the "" that begin each line either.
Besides, if
it has gone around that many times we've probably already seen
it.
9. Craig Shergold (or Sherwood, or Sherman, etc) in England is
not dying of
cancer or anything else at this time and would like everyone to
stop sending
him their business cards. He apparently is no longer a "little
boy" either.
10. The "Make a Wish" foundation is a real organization doing
fine work,
but they have had to establish a special toll free hot line in
response to
the large number of Internet hoaxes using their good name and
reputation.
It is distracting them from the important work they do.
11. If you are one of those insufferable idiots who forwards
anything that
"promises" something bad will happen if you "don't" -- then
something bad
will happen to you if I ever meet you in a dark alley.
12. Women really are suffering in Afghanistan, but forwarding an
e-mail won't help their cause in the least. If you want to help,
contact your local legislative representative, join Amnesty
International or get in touch with the Red Cross.
13. As a general rule, e-mail "signatures" are easily faked and
mean
nothing to anyone with any power to do anything about whatever
the
competition is complaining about.
14. KFC really does use real Chickens with feathers and beaks
and feet.
No, they really do. Why did they change their name? In this
health
conscious world, what was KFC's name? Kentucky FRIED Chicken.
FRIED is not
healthy. So with the help of a focus group, they changed the
name to KFC.
It's short, doesn't offend dieters and it's easy to remember.
15. Another thing, just because someone said in a message, four
generations
back, that "we checked it out and it's legit," does not actually
make it true.
PS: There is no bill pending before Congress that will allow long
distance
companies to charge you for using the Internet. Bottom Line...
composing
e-mail or posting something on the Net is as easy as writing on
the walls of
a public toilet. Don't automatically believe it until it's
proven false...
ASSUME it's false, unless there is proof that it's true.
Now forward this to everyone you know or the program I just put
on your hard
drive while you read this E-mail, will open up your CD-ROM and
reach out and
slap your face!
