Howdy claybuds,
I have several bags of chemicals from an old potters barn in Ohio. =
Wondered if anybody knew what they were....
Ferro Frit 3247 50#
Ocmulgie 5#
#92 Black Reusche 50# (looks like a stain or maybe glaze)
2:61 clay 50# bag. from Ky/Tenn Clay Co. in Mayfield =
Ky. Looks to be a ball clay but not =
sure.
All these chemical were sealed in plastic bags and from the 60's. Any =
help would be greatly appreciated. These were all going to the =
landfill!!

Frit 3247, according to Bill Hunt's in valuable list, CM, May 1978, is a
BARIUM frit. BaO 1.00, Al203 .150, SiO2 2, mol wt 288.8 fusion temp 1850F
i think Ocmulgie was/is a clay. I expect the Kentucky/Tennessee clay is a
ball clay, and I would suggest you test in in a glaze that has a fair amount
of clay--I mean just replace the ball clay you now are using, with it. If
it goes back to the '60s (may I say, don't we all?) it probably is different
enough from what is mined unde the same name now as to make no never mind.

Ocmulgee is very nice clay from the Ocmulgee river in Georgia.
Don't know the others.

Information on Ocmulgee Clay from the Net,
Natural earthenware clays are those clays which contain fairly high amounts
of iron oxide in combination with fluxing agents like calcium oxide and
sodium oxide. These clays are plastic and fire to the warm earthy colors of
tan, orange, red, brown, etc., although their unfired colors may range from
red to grey to green to blue to black. Their normal firing range is
approximately C/06 to C/1 or 2. Some clays of this type can withstand
firings of up to C/4.5.6 without bloating or melting or showing other signs
of being over-fired. We use three clays of this type at Alfred and they are
easily available throughout the East. They are Redart, Ocmulgee and Calvert.
These clays make ideal body ingredients for C/4.5.6 bodies. They are fine
grained, plastic, richly colored, and very dense when fired to C/4.5.6. One
can find these "common" red iron bearing clays all over the U.S.A.

Hi again Sandy!
There is still a Reusche company (or two?) involved, in a way, with=20
ceramics - it provides paints for china and glass painting. Whether the=20
company is the same one that produced the Reusche clay is something you=20
would have to ask them, and of course the present owners may not know or=20
have retained records from 40 years ago. Here are the addresses and=20
other contact information I found:
Erik Wagg
Chair, Reusche & Company,
1299 H Street, Greeley, CO. 80631,
970-346-8577,
ReuscheCo@aol.com
(Enamel painting and screening supplies)
As late as 2002, Mr. Wagg was an officer of the Rocky Mountain Section=20
of ACERS.
From the ACERS (American Ceramic Society) site:
http://www.acers.org/membership/sdc_pages/sdcdisplay.asp?ItemID=3D40
Another version of this, with a different contact name is:
Reusche & Co. of TWS Inc.
Jon Rarick
1299 H Street
Greeley, CO 80631
970.346.8577
970.346.8575 fax
From the Stained Glass Association of America:
http://www.stainedglass.org/main_pages/association_pages/sgaa_accredited_=
members.htm
Here's another, listed on a glass decorator discussion list:
Reusche & Co.
2 - 6 Lister Avenue
Newark, NJ, US
07105
Telephone: (201) 589-2040
Facsimile: (201) 589-0478
I found several references to this New Jersey address.
Here's a link for the Kentucky-Tennessee Clay Company:
http://www.k-tclay.com/
Ball Clay / Kaolin / Feldspar
"Kentucky-Tennessee Clay Company's corporate roots run deep in the rich
mining territories of Western Kentucky, Tennessee and Mississippi. Back
in 1890, the small Mandle Clay Company, which a quarter century later
became K-T Clay, unearthed the original Old Mine #4 Ball Clay, a raw
material which has become the standard by which all Ball Clays are
measured to this day."
One of the companies mining clay in the Ocmulgee River area of Georgia=20
is the Cherokee Brick and Tile Company.
It has a Yellow Pages ad at this url:
http://www.yellowpages-ads.com/00706288
I know you were already sent this next information via Clayart, but I=20
include it for the sake of completenes:
