What news!
A geologist exploring in our area (Helmer-Bovill, Idaho) has me testing =3D
a new Potash Feldspar find his company is thinking of putting into =3D
production.
Chemical Analysis 18.36 Al2O3....64.17 SiO2....12.75 K2O....0.53 =3D
Na2O....0.03 CaO....trace MgO....0.04 Fe2O3....0.41 TiO2....0.74 =3D
BaO....0.03 P2O5....0.07 SrO....trace MnO....trace Cr2O3.
In firing tests as a body addition with Helmer, it produced a =3D
translucent porcelain at cone 10 and is very clean and white. They plan =3D
to magnetically separate the rest of the iron. At last, a local Kspar!
Let's keep our fingers crossed that this one gets off the ground, as =3D
there are millions of tons of this in the deposit and it is all this =3D
pure.

Hi Michael & All,
I talked to the geologist at the Renaissance Fair this
weekend & he showed me some of the stuff you fired for
him. An amazing hunk of fired feldspar, looked like
milky glass.
He said some things that have me shaking my head in
amazement, including the tonnage of clay they were
talking about mining. I hesitate to repeat the number
here, it sounded so vast I must have heard wrong!
He said there was a high quality blue ball clay too,
which fires out white.

Who got a good dose of sun, wind, snow flecks, cold
temperatures, more sun, and rain at the fair today.

What news indeed! My imagination immediately constructed a
body from this for wood and/or salt firing. Keep us posted.

How long before this comes to market? This sounds great. Sounds like just
the ticket for a blue celadon over the porcelain, too.
