Is anyone else out there working on a substitute for this?
We have a material that is very similar but less plastic,
a little less iron and a coarser grain size. That means I
have to add some ball clay, we have to grind it as fine
as possible and I have to add a little iron.
I am calling it Red Firelclay, there is a link to it at
www.ceramicmaterials.info on the Newman record.
Anyone have any comments on Newman, what properties
about it are most important to you?

One thing about Newman Red is a very high
cone equivelent, so the clay is good for an
addition to a high fire body where color is needed
or wanted. I've used as much as 10% to give color
to a stoneware body, but the clay has very low
plasticity, as does Redart. But because Redart
melts at a much lower temperature, Newman Red
is a much better choice for an addition to a high
fire body,

Hello Tony, and all Claymakers,
I've never used Newman, but have used other clays from the vicinity.
Looking at your page on Newman Red Fireclay, I notice that the producer
is/was Gladding McBean in Lincoln, California. There is a supplier in
Sacramento where I get Fireclay, Industrial Minerals (IMCO). I use the
IMCO 400 fireclay, which is "the same as" Lincoln #60 (extinct?), only
milled finer, to 200 mesh. I think is has around 2% Iron.
They also sell IMCO 800 fireclay, containing more Iron (6% ?). It is
probably finely milled also, but might be close to the Newman Red you
want to replace, it's orange in the raw state. They have a website,
http://www.clayimco.com/ though I couldn't find the raw clay analysis.
Laguna carries both in their catalog.
Thanks for all the good information on your website, it's been fun to
look at!
best wishes,

Thanks.
I checked my records and I have tested both Lincoln and Imco
400 in our lab. Neither is a fireclay, they are both zero porosity
by cone 8. The Imco is more vitreous. They are both very fine
but the Imco lacks the scattered impurity particles in the 35,
48, 65 mesh range. The Imco material is a very nice base for
middle temperature bodies. Lincoln is not extinct, at least I
do not think so, we stock it at Plainsman and we have lots
here. I cannot find the website for Lincoln Clay Products,
does anyone know if they have one?
I will check into the Imco 800, it appears to have less iron
but the Newman is also orange. Gladding McBean has a clay called
Jasper that is higher in iron, I wonder if they still sell that?

Tony,
I believe Lincoln Clay Products has been swallowed up by Gladding
McBean.
Good Mixing,
