barnard earth vs. barnard clay

I have just had a very interesting experience.

At the college, on a regular basis, I mix Barnard earth with water, and
use it as a wash on the faces of some mugs I am making. It is quite
dark -- a deep brown -- almost black. I wash it off to accent the lines
and curvatures of the sculpted faces. It highlights them quite nicely,
and leaves a very dark brown hue -- where it is thickly applied.

At my studio at home, I have Barnard clay, which I assumed was just a
different name than Barnard earth. I used it for the first time today.
To my surprise, I found the powder lighter in color than the Barnard
earth at school, and when I added water, it mixed to a lighter hue, with
more yellow tawny hues. As I painted it on, it went on much smoother
than Barnard earth. It definitely had a more watery clay feel when
painting it on with a Chinese brush. Barnard earth pulls and has a
resistant "dry" feel when it is painted on thick. On the other hand,
the Barnard clay mixture never pulled on the brush like that. It went
on very smoothly. And, quite unlike the Barnard Earth at college, when
washed off, the remaining color was much more tawny.

So, who has experience with both Barnard earth and Barnard clay? I'm
guessing Barnard earth is the pure oxide and Barnard clay definitely has
some clay mixed in -- the color is definitely different.

I googled Barnard Earth vs. Barnard clay and did not find anything
definitive. I will go back and google some more.

But I thought I'd throw this question out: What is the difference
between the two -- and has anyone else besides me used both?

much thanks
