That information in Charan's report really puzzled me....but I am =
wondering:

I am assuming that the tests were part of a regular bisque ??

If true, then: slow low temp intial firing and moisture from greenware =
would contribute to more soda ash being deposited on the surface? =
Carbon effects from the regular bisque would be captured? This would =
also account for the wax resist doing it's usual on a shino glaze. =
Dependent on the clay content of the work the pieces would not =
re-oxidize because of the fireclay/ballclays, as the bisque firing =
continued/finished.

If any or part of these conclusions are true then why did the pieces not =
re-oxidize and lose carbon trapping in the beginning of the gas firing =
prior to usual reduction phase? Does this result indicate that the thin =
coating of fluxed soda is holding the carbon trapping and would not be =
affected by the assumed oxidation conditions ? Puzzled or did I just =
answer my question ? : MarjB =20

ps: to Wayne - a Eskimo/Iniut Roll is turning/rolling your kayak 360 , =
with you in it and in the water !! I would imagine that some people =
experiencing recent hurricanes would feel that they have been "rolled".
