Dear Melinda;

there are many deposits of both Andesite and Basalt in western
Oregon. I mine several deposits of weathered Andesite along the
Middle Fork of the Santiam River. I have used them when ball milled
as bodies in electric kilns at C6...... beautiful, ringingly tight
bodies.

I also use the material with the addition of 6% Madrone ash as a
glaze at C10_12. Here's a pic:

The Adirondack Mountains in northern New York, especially in the
Sanford Lake district, have been known for basaltic hornblende and
garnet =3D96 black sands were mined there some years black. Different
terms are used for these rocks =3D96 the black sands are most likely
gabbro, the intrusive (plutonic) equivalent of basalt. The chemistry
is the same.

I got some black aquarium sand to try in a glaze last year and tracked
it to this area of NY. Once fired, it lost all its great black! I
called the company selling the aquarium sand and it was just plain
sand colored synthetically with an organic polymer that burned out
when fired. They have done a great job with this black coating -- it
fooled me. It was strange to expect black but get clear-white out of
the kiln.

Here is a nice reference that gives locations for some readily
accessible (real) black US sands:

Does anyone know where, in the United States, is there a source of black
volcanic basalt sand, such as you would find on a river bank or river's
edge. NOT for purchase from a ceramic supply, but some waiting on the
ground to be hauled off and sifted......I know there are black pre-made
bodies....but that are not what I am talking about. Can anyone help me
out?

Hi Melinda,

Some shows up on the western bank of the Delaware bay from time to time. =
=3D
It is usually in a very thin layer (1/4-1/2 and inch) and doesn't stay =3D
around very long. Of course in the last 2 or 3 years they have been =3D
doing a lot of beach replenishment in the area I found it and it will =3D
probably take a few years for the natural forces of nature to =3D
reestablish those layers. If you want a sample I have more than I need.

Regards,

John

I used to live near black sand beaches on the Isle of
Hawaii. An unmanned lighthouse stands at the eastern point
of the island. The black sand there glitters with green. The
Hawaiians believe that ghosts called the night marchers walk
along that beach during the full moon. According to local
custom, it is taboo to remove the sand or rocks from the
island.

HI Melinda and all
There are black veins of hardend sand at the clay hole here .
East of Austin twenty miles.
If you are in the area you can gather some for free.
There are also deposits of purple and brown and some red sands.
The clays are red black gray or brown.
Wear heavy shoes and pants as chiggers are out and yesterday I found a
rattlesnake.
Offer extends to anyone on clayart.
