1. As explained often before, by me and others, there ARE no c anything =
glazes. There ARE glazes that on X body, fired to Y temp/cone, in Z =3D
atmospeheric conditions produce a glaze that makes a particular potter =3D
happy AND meets the requirements=3D20
demanded of a proper glaze: no leaching, crazing, etc.
2. A glaze is a mixture of materials. These materials provide =3D
ingredients. The proportion of ingredients is what forms the final =3D
glaze. As most of our materials are mined, and mine runs vary, and some =
materials come from different mines altogether, even frits (according to =
teh late, great Mr Isaacs of Hammill and Gillespie) will, can, may vary =3D
from batch to batch.
I do not understand why people who actually can tell a Merlot from a =3D
Rioja and understand red wine is not necessarily a generic thing cannot =3D
appeciate this. NOr can I see why people who understand that a Pippin =3D
is not a Macintosh apply, and you need to adjust your apple-piec filling =
cannot grasp this.
3. Ingredients can be supplied by different materials. =3D20

Hi, John, Lili, and you all,
Very punny about "...how can you master them!!!??", John.
In my reading of the MC6G book, its main purpose is pithily printed
on the front cover:
"Improving Durability, Fit, and Aesthetics"
Perhaps Lili (note spelling) was being a bit too strict or nitpicky
(and there are many reasons to be so, and I wouldn't presume to
challenge its usefulness or her right to do so).
My interpretation (uh-oh) of Lili's message was that a potter,
especially a neophyte, would save time, money, energy, and
frustration by NOT using any glaze that's called "cone 6" and expect
it to work (with their clay body in their kiln fired as they wish)
I know very well your expertise, familiarity, and facility with
glazes and their use. You are the man to me and many others who love
your book. But in your quest to free the world of oppressive recipe
hoarders, you may have missed something here.
A good part of MC6G deals with making sure that a glaze formulation
works with the body one is using, how to identify when it is or isn't
working, and how to correct it.
It also goes into very welcome detail about assuring that pots which
may be used for food or drink don't leach harmful chemicals.
Perhaps this is why so many of us recommended it to Linda Mccaleb
(who, as you may recall, started this by saying "I'm looking for a
book on cone 6 glazes. One that will fit my cone 5-6 Porcelain and
A couple of days ago you wrote:

So in case you missed it, after the kerfuffle about whether she
wanted access to thousands of recipes, including some of those in
MC6G, or "... a book on cone 6 glazes." she wrote "Yes you are right,
I do need to know what to do if there is crazing, or crawling...I do
need and will get the books."
ps John, how do you know that the Zen teacher exists?
pps Lili, it would be helpful to those who were/are( or will be in
years to come) following this thread, and to those who have decided
to ignore this thread, if you would NOT change the subject header.
Maintaining the subject header keeps threads in tact and allows
people to read (or ignore) the entire conversation. Surely someone
who writes as carefully and considerately as you can copy and paste
the subject header into your message.

Zen Masters are abstract concepts to most. I decided to become a
potter while I was an attendant at my Zen Master's funeral. I wanted
to make urns.
Last year was my "year of the tea bowl."
This year is "the year of the covered jar and urn."
