And many of you answered with the name(Macula Pomifera), and
suggestions on where to find them. I'm thinking the bobbies around Kew
Gardens would be on your case in a hurry Janet, if you show up at harvest
time with a burlap sack! Seriously (but with fun!), Ashes from fruit are
the highest in phosphorus content that I know of. Not just osage oranges,
but apples, pears, plums, etc: fruit concentrates phosphorus just as the
rice seed husk concentrates silica. Each plant form has its job and its own
'recipe'. So why do we want some phosphorus in our glazes or on our bisque
anyway? The same reason David Shaner used phosphorus in Shaner's Red: A
little or a lot of P2O5 will shift the iron color to the red spectrum,
especially when the reduction is followed by a slow or soaking cool in
oxidation. So it is wonderful, but not surprising that hedge apples and
regular apples and other fruits would yield these warm colors. look around
your own garden or street for free fruit to try. you can also get a lovely
"Chun" soft blue with small additions of phosphorus to a limestone glaze.
Just keep the iron down.
When I was studying pottery with Bob James and David Stannard at
the U of Oregon in the late 50s and early 60s, we collected apple pulp in
garbage cans from the cider producers around Eugene, and reduced it to ash
in large bowls in the muffle kiln. We got some pretty spectacular colors
from time to time; and the rotting apple pulp kept the Dean out of our
hair! While teaching at Anderson Ranch in the early 70s, my wife Bev was
given some 'osage orange' sawdust with which she made a beautiful dye
lot.......pumpkin/orange. When this yarn was dyed in the indigo vat, a
beautiful limey green developed. Thinking laterally and trying to open the
discussion a little here in Eugene, Hank

I think Jack Troy who fired McDonald fries on plates to get salt
flashing.

And there was a potter in Mendocino I vivited in '67 while travelling down
to Baja who put his plates in the kiln with the garbage and bones from
dinner on them. Sometimes they turned out great; and his kiln stunk to high
heaven. Hank

Do you have any photos of your hedge apple firings. I sure would like to
see the results.
