just want to report that my `blue` celdon's are green.
and that firing down is marvelous.

now at the fourth firing in a row.
no loss.
all pots fired to perfection.

at 2000 i fired half on for three hours.
nice.

the surface of the celedon's were very nice.

i am using a very high iron bearing clay and i did
not expect the blue. the green is very interesting..
not that army green.
almost blue if you pretend.

thanks to craig martell and john britt..and of
course, my new hero, hank murrow.
(his article will appear this fall in ceramics monthly.)

i am going to try some more celedon experiments, and
look forward to it.

Dear Mel;

While you are at it, try getting the titanium (rutile, etc)
completely out of your clay, OR covered by a completely Ti-free engobe to
get the blue you are looking for. The slightest Ti will turn things green.

Cheers, Hank
