I recently saw an article about a potter using the "silt casting"
technique...beautiful work. I'd like to try it, but the piece was very
general about what constitutes "silt." Only mentioned 70% fine sand, 30%
clay. No mention of how the two are mized--how moist clay should/ could
be, etc etc.
Has anyone on this wonderful list made "silt," and could you pass this
technique along?

Richard, you have raised an interesting question.
Being an old displaced Alaskan Sourdough, I collected up several
materials unique to Alaska before relocating south - two 5 gallon
buckets of Mount Redoubt volcanic ash, one 5 gallon bucket of chunks of
"Alaska Clay" dug from a local hillside, a 5 gallon bucket half full of
moose nuggets, and a couple of 5 gallon buckets of genuine Matanuska
Glacier silt.
I would like very much to know how to work with that glacial silt. I
think it has possibilities.
I too would like to know how to "silt cast"
Regards,
John Rodgers

Google terms you could try are "green sand" "mold sand" "mould sand" "silt
mould" "Silt mold" "sand cast" "silt cast" - there will be some overlap, and
some articles are written for metal cast procedures (still of interest) but
it will give you some idea of what there is out there. I found a couple of
sites that listed 85% sand and 15% clay as the "silt" proportions. Another
had about 5% coal powder and another had a small percentage of iron (oxide?)
Sincerely,

Please add a "me, too" for that request. Joe and I saw him in a show
on tv, and the article of his work has that was in one of the major
ceramic magazines recently. I'll try to find it and post the magazine
name.
Until then,
Us, also
Rita & Joe

Silt has also been used to great effect in glazes:
