or and a question on castable/fir sawdust
Hi Folks,
I've been off list a while and this is a new e-mail. I was on for a while a
couple years back as ben@thecommonpot.com. Ben's a nickname my given name
is Robert.
Anyway I finally made it back to Oregon. Got a house in Cottage Grove last
month. Hi Hank. Unfortunately my clay equipment stayed in San Diego so
I'm currently trying to piece together a studio. I need a wheel, extruder
and gas kiln around 20 cu ft. If anyone in the area knows of any used let
me know. Also I'm finding some local clays that research indicates may have
some refractory qualities. I'd appreciate in anyone have space in C10
firings for some test tiles. Let me know
Thirdly, I'm considering using a homemade castable to build a multi fuel
kiln if I cant find a decent price gas around here. I've got a mountain 10
miles down the road out my front door that has 9 million cu ft of high
alumina (30%) flint fireclay on top of it. Question is I got some fir saw
dust from our local sawmiller to use in the mix. He warned me that some
folks a while back ( he's 70) tried using his fir sawdust for cementious
roof tiles and that it interfered with the bond reaction in the cement, or
caused them to break down early.
My first test casts seemed quite weak compared to my past experiences. I
might have mixed too dry though. For my tests I'm using portland cement but
will be buying calcium alumina for the kiln if I got this route. If
anyone has used fir sawdust in homemade castable successfully or otherwise I
would appreciate hearing your experiences.
Glad to be back,
TIA,
Robert

Bring them by, I will be firing in a couple of weeks. Call @ 342-8429.

Suggest you contact Tom Rohr at Pleasant Hill Pottery (he is the
faculty at LCC) as he may have useful ideas. Where is the fireclay?
What deposit? News to me. I do dig a rhyolitic porcelainstone near
Steamboat OR.
Cheers, Hank

Thanks for the reply Hank. I've been in Eugene for a few months but kind of
scrambling to get on my feet. Would've called sooner. My family is up now
and we have a house in Cottage Grove. Starting to mellow out a little. The
fire clay is on Hobart Butte in the southwest corner of Lane County near the
town of London. It was quite thoroughly prospected and documented in WWII
as a potential source of aluminum ore. Willamina Brick used it for a while
back in the day and the quarry face is still there and accessible albeit a
bit steep getting there. As near as I can tell it's BLM and no one seems to
care about small amounts. Kind of place the locals go to shoot skeet and
have a few beers. I can send you the docs if you like. I'm also pursuing
some references in Cottage Grove from the same time frame. I've narrowed
them down to two 80 acre properties, one of which I can access to prospect
and the other, which is owned by Werehauser, I'm stumped to gain access.
Again Hobart is flint... extremely non-plastic. The most detail on the
Taylor that I have is reported as a pink shale with 2 or 3% iron and 30%
alumina. Again not likely plastic but potentially could bring up a low temp
plastic clay. There are also plastic clays in both places which could be
derived from the refractory deposits but I haven't walked enough yet and
haven't had a kiln. Keep in touch.
