Some people seem to take umbrage with John and Ron's proprietary and
somewhat protective approach to their book. The key here is that it was
self published. Their worry and financial buy-in are different than if
one of the bigger publishers had printed the book. When you self
publish, the whole job is yours to do, print, promote, distribute, etc.
I submit that this would tend to make your perspective different.
When it comes to copyrighted material though, it shouldn't be treated
different by us. Even if a publisher is doing a big part of it, the
financial risk is still there for someone.

Hey!
There have been some "peculiar" expressions of praise and denial
over the issuance this year by John Hesselberth and Ron Roy of their
book
"Mastering Cone 6 Glaze". The odd comment hinted these gentlemen were
seeking sales to line their pockets.
Let me make clear one thing: if J&R manage to recover the costs
of
producing this publication, as independent publishers, they will have
achieved something that very very seldom happens.

Hey!
There have been some "peculiar" expressions of praise and denial
over the issuance this year by John Hesselberth and Ron Roy of their book
"Mastering Cone 6 Glaze". The odd comment hinted these gentlemen were
seeking sales to line their pockets.
Let me make clear one thing: if J&R manage to recover the costs of
producing this publication, as independent publishers, they will have
achieved something that very very seldom happens. and I know whereof I
speak ... I was, years ago, in publishing as editor/manager of an
engineering publication issued monthly. In an excellent year, we made 10%
profit (before tax) on a budget of $2.5 million. There were lean years
when that ROI was close to zero. Book publishing is even more risky.
Should you be a ceramics engineer in industry you will have surely
been fed on Parmelee/Harman and Kingbery, and hence be fully aware of
"old-hat stuff" (as one Clayarter said) covered in the J&R book. Yet, in
five years of attending NCECA conferences, the only such persons I met
were in the exhibitor booths, not those attending as potters and teachers.
There is a real need for younger potters of today to become glaze
literate. Who, for example, can complete this request for me:
Please design for me a gloss base glaze for Cone 3. I give you a
hint: start with the Watts Formula: 0.4 KNaO; 0.3 CaO; 0.3 ZnO; 0.5/0.6
Al2O3; 3.5-3.55 AiO2. If you hand-calculate, it will take awhile; if you
do it via a glzcalc program, it will still take sometime if you do it via
interpolation, and perhaps the fastest way is a computer program that
allows you work directly from a Seger Formula to a Batch Recipe.
In the J&R book are examples of Seger Formulas, alongside Batch
Recipes. In my view, this will encourage many potters to explore further
these relationships, and lead to more potters becoming glaze literate.
It helps, too, that the examples of good glazes cited in the book
actually do produce excellent interesting glazes for functional ware.
I await my new C3 base glaze. TIA. Peace. Tom B.

Here you are Tom. It took one minute using Matrix - direct Seger formula =
to Batch Recipe.

Check this one Tom,
From Dr. Chris Hogg's program:
Flint 20
Kaolin 5
Nepheline 60
Whitimg 8
Zinc oxide 7
Now a statement from Richard Zakin's program:
"If glazes in this category contain reasonably strong melters
they will be vitreous. Their high silica content encourages
durability and transparency. Their normal alumina content
discourages glaze flow even if strong melters are present.
This is an excellent category for tranparent glazes."
