Just bought a grinding wheel composed of material designed for grinding
metals, and it works much better on fired ceramics than my ordinary one
did. Cost twice as much but well worth it. Maybe most of you already
knew about this, but for those who didn't..... Lesley.
ps I also bought a tiny diamond bit set for my dreml tool, to see if I
could get off a glazed-on lid. I could have, but it would be easier to
make another. I'd have to be madly in love with the piece to put in all
that time!

Hi les...I have a green wheel (actually green in color and name) on my
gringer, and also a flapper wheel for smoothing bottoms...VERY satisfactory
for ceramics... and a bit pricey; More than $60 as I remember for the
flapper wheel, but it works better than anything I have ever used. Lori

The best bet for a grinding wheel for fired clay would be a lapidary wheel.
The silicon carbide is a much finer grit, and compressed to a much higher
pressure, making the wheel harder. Adding a water drip to the grinder will
also speed up the process, as grinding ceramic materials will "glaze" over
the wheel quickly, otherwise. If you do a lot of crystal glazes, and grind
the bottoms of the pots a lot, then a diamond grinding wheel would be a must
have piece of equipment.

These links will give you a general idea what is out there...many lapidary
tools would find a nice home in a pottery studio!

Lori -
I am wondering why you paid so much for a abrasive flap wheel. You can get
nice 6" by 1" ones from Grainger Supply for about $18, and they last a long
time. We replace a couple of them every semester, but that is with all my
students using them.
