marshall brown from smith sharpe has sent a
note to clayart explaining `glaze eraser`.
marshall is a fine fellow, and is a friend of many
potters. he can be trusted.

this is not an advert, he talked to me about
some misconceptions in the product.
here is his reply:

A few comments regarding the recent thread of discussions about GlazeEraser=
=3D
=3DAE

The comment that simply attaching a broken kiln shelf to a bat will work is=
=3D
a little too simplistic. There are many types of Silicon Carbide plates=
=3D
manufactured in the US =3D96 at least 30 or more. The particular type of =
SiC=3D
used to produce GlazeEraser is a specialized form with an multi-faceted,=
=3D
open grain crystal grain structure that is particularly effective in=3D
grinding and cutting under pressure. The firing process required to=3D
produce this product is very lengthy and at a very high temperature. =3D
Traditional SiC material used for kiln shelves would be too smooth and thu=
s=3D
relatively ineffective as a grinding surface.

GlazeEraser is a solid disk of extremely hard SiC material (the 3rd hardest=
=3D
material on the planet). There will not be silicon carbide dust coming of=
f=3D
into a splash pan, but there will be ground glaze glass and clay body, so=
=3D
it is important not to get this debris into your clay slop buckets as=3D
pointed out in our literature and video. Dust creation of any sort is=3D
minimal since you are grinding at a relatively slow speed compared to a=3D
high speed grinder. Most users end up wet grinding which further minimize=
s=3D
airborne dust. The slower speed makes it much safer for classroom or=3D
studio settings. Make no mistake however; with the right combination spee=
d=3D
and pressure, GlazeEraser will grind right through porcelain and stoneware=
=3D
clay bodies and even hard metals!

Finally while it is considerably more expensive than adhesive disks with=3D
grit glued to a paper surface, GlazeEraser will outlast these disks many=
=3D
times over and there are no loose grit particles that will ultimately shed=
=3D
off of the surface and into the air or splash pan.

I always tell prospective customers that if you need to grind glaze off of =
a=3D
lot pots after every firing, you will be better off buying high speed=3D
grinding equipment for the time savings factor alone. But if you only nee=
d=3D
to clean up random glaze runs and other kiln debris typical of most studio=
s=3D
or classrooms in a safe and controlled manner, GlazeEraser may be the righ=
t=3D
tool for you. We only want happy customers and so we offer a money back,=
=3D
satisfaction guarantee.
