Mike's latest book, Oriental Glazes, has just been published. It is not
only an excellent book for its recipes and examples by numerous potters
working with reduction, but also because of Mike's approach to showing
how to understand the differences between recipes. His approach is to
analyse recipes into % weight analyses and to plot the Al2O3 and SiO2
figures so obtained. It becomes a lot more interesting when he also
includes the analyses of the different raw materials and also plots
these on the same graph. The graphs show the area where transparent
glazes will be found and how in a pictorial way the other raw materials
may affect a recipe if adjustment is being sort say, make it more shiny
or more matt.
This is a poor summary of this aspect of the book, but I think that it
is worth considering always giving the % weight analysis with a recipe,
rather than its unity formula. If you get a chance to read Mike's book I
would be interested to hear other views on this.

Dear David Hewitt,
Can you give more details please?
<>
Does it supersede books on the same topic by Nigel Wood?
Does it deal with glazes from the Indo-Chinese nations? This seems to
be an area which has not been explored or exploited.
Best regards,

No, it is quite different.

It is not an historical analysis of the glazes from the Indo-Chinese
nations. It is a book for those who wish to produce Celadon, Shino, Jun,
Tenmoku, Oil spot, Tea dust, hare's fur and the like.
It is full of recipes and examples (photographs) of pots made by many
well known potters working in theses areas.
To me, however, the great interest was in its approach to glaze
analysis, as I indicated in my earlier email. This emphasises the value
of looking at % weight analyses rather than unity form analyses. I think
that it would be interesting to see Limit Formulae developed on these
lines.

Dear David,
As much as anything I was hoping for the publication details;
Publisher. ISBN etc. Then I can order it up through the library.
I believe several people are using percentage representation of
molecular oxides as an addition to the unity formula. Surely some of
the Glaze calc programs do this.
Accepting what you say about the scope of Michael Bailey's book, it
would be a pleasure to read information about historic glazes from
Cambodia, Thailand, Myanmar and the other indochinese countries.
Thanks for responding.
Best regards,
Ivor Lewis.
