I did a glaze test for a 5-6 glaze test useing common brick clay. I wanted
to know if any one has a Chemical brakedown of common surface brick clay. I
have one for fire brick clay but I can't use it. I want to have the mocular
weight so I can play around with it. I know clays are not alll the same but I
wanted to find the general Idea. Thanks From Al
The glaze I have that uses Brick clay works in the cone 5-6 range I wanted to
raise the melting point.

I worked in a brickyard in central Pa. They actually
made chimney flues.The clay they used was brought
straight out of the mountain , crushed, screened and
worked.The clay was pretty much vitrified at 1900F.
I guess my point is that it would be hard to pin down
what common brick clay is.Most i've heard of are low
fire.
If you could explain a little further what you are
trying to accomplish,i'm sure somebody out there will
be able to help.
