Greetings all, I am looking for a source of course feldspar to make a
crawly shino glaze.
I was lucky enough to attend a workshop by Ken Matsuzaki; an accomplished
potter in his own right who worked with Shimaoka for many years. Ken
described the process of shino firing that has captured my thoughts ever
since. He spoke of where he gets his local clay and that he processes the
feldspar for his shino glazes himself with a huge wooden mortar and pestle.
Well, actually his apprentices do, but anyway... He stated that the way
that he gets this amazing effect where the shino crawls in a way that I can
only describe as plate tactonics is to mix up a very thick batch of a
felspar and swoop it on with a cupped hand onto the pot that already has a
layer of lower melting point feldspar. See the teapot at the bottom of the
page
http://www.e-yakimono.net/html/matsuzaki-ken-er.html
and also
http://www.trocadero.com/japanesepottery/items/52316/item52316store.html
for an example of this effect. This second link is not by Matsuzaki Ken
but is a good example of what I am looking for.
I tried this by mixing up a batch of Custer Feldspar and glooping it onto a
vase with a shino already on it. It turned out very unique but looked more
like frosting than the rich varied effect that I am looking for.
So I am wondering if anyone knows of any source of a coarse grade feldspar.
It seems that every pottery supply that I am aware of carries only 200 mesh
or finer. Apparently Feldspar Inc. Sells a mixed coarseness feldspar but
in 2000 pound increments! I am looking for about 5-50 pounds for my
purposes.
Thanks in advance for any help anyone can provide.
Cheers
Lloyd
