I'm seeking information on Lincoln Fire clay.
Can anyone West of the Mississippi please share information on a fire
clay called
( Lincoln 60 Fire clay )?
I'm testing and looking for a clay body with (Lincoln 60 fire clay) as
the main
clay in the stoneware body. I hope to develop this clay body to fire in
the
^9-11 reduction range, and work in salt/soda/wood too.
Here is the clay body that I'm now testing.
Any ideas greatly appreciated.
