Dear Larry Nakanishi,=20
This is interesting......<workshop in Australia and was wondering why since he learned more than I =
taught". He mention that he saw the porcelain potters using tungsten =
carbide tools to trim their pots after firing to something like cone =
020. They would turn the pots (much like a lathe) to obtain much thinner =
walls than normally possible. I was wondering if you know of this and if =
similar tools are available.....>>
I have had little contact with the Studio pottery industry for some =
years so do not know who is doing this or where they are located. =
Johanna De Maine, who is a member of this group, lives in Queensland. =
She designs and makes highly decorated Porcelain pots and may be able to =
give you more information. You could also contact the Ceramics Workshop =
at the Jam Factory in Adelaide. They will have a web site
I recall seeing a film a couple of decades ago where they were using a =
modified metal lathe to refine porcelain. Teacup blanks were jollied to =
constant internal dimensions and turned with their axis of rotation =
horizontal on the outside and foot. If the lathe is set up correctly, =
standard forms of tungsten carbide tipped tool would perform the task.

You make an important point. With these kinds of tools, you
are not so much trimming as you are machining the pot. Of course,
if that is what you want, it is the tool you use. But I don't want
my pots to look "machined" or lathed.

Ivor,
What was done to deal with the silica dust? I would
imagine trimming bisque would not be good for the
lungs.

Dear Charlie Hightower,
<bisque would not be good for the lungs.>>
No idea ! ! I just saw a film which illustrated the production =
processes in an English factory. Yes, it would be health hazard. But not =
a process I would engage in.

machine industrial bisque parts with a water stream. that works as a lubricant, and to keep dust near zero. also keeps the parts cool during the machining.

I would think it would be fine if one could hang a 5
gallon bucket over the wheel with a hose slowly
running water onto the pot as you trimmed the bisque.
I often will sand out small defects that make it to
bisque. I do this underwater with a wet/dry sanding
sponge. No mask needed. I just fill up my sink half
way and have at it.
