Dear Janet Kaiser,

Interesting reflections on what is becoming a dilemma of increasing =
proportions as more people adopt lower temperature stoneware firing =
temperatures.

Depends on how you define the 24 Karat stuff?

I think there is a common idea that True Porcelain is light to white in =
colour, has a degree of translucency which can be seen and that it will =
ring with a clear musical tone when struck lightly.

Now potters can go through the rigours of concocting their own blends of =
clay, spar and quartz to make this happen or they can go to a clay =
supplier. If the supplier tells the potter it is a porcelain, said =
potter can ask to see a sample of the fired material. If one of the =
three criteria missing then you win.

Best to avoid using the term Porcelain altogether. Demi means half. =
Question, Which half? Could use Faux, but why bother? Best tell both the =
Potter and your own clients that it is a White Stoneware which has some =
of the properties of Fine Porcelain but is deficient because ......

Lets face reality. Firing Porcelain which has all of the qualities is =
not an undertaking for the faint hearted. I doubt if more than a =
moderate proportion of potters or ceramic artists who use the wheel have =
the ability to throw thin enough and turn with precision to achieve =
superior results. But I don't mind being proved wrong on that score.

May 'Porcelaineous Stoneware' suffice? - as an honest
appelation?

Dear Janet Kaiser,

I think there is a common idea that True Porcelain is light
to white in colour, has a degree of translucency which can
be seen and that it will ring with a clear musical tone when
struck lightly.

own blends of clay, spar and quartz to make this happen or
they can go to a clay supplier. If the supplier tells the
potter it is a porcelain, said potter can ask to see a
sample of the fired material. If one of the three criteria

doubt if more than a moderate proportion of potters or

Dear Phil,

You suggest <appellation? >>.

No! There is the inference that it has qualities associated with =
porcelain. Which one do you wish to identify, Whiteness? Translucency? =
Vitrification. To what degree is it white or light coloured, To what =
degree is it translucent, to what degree is it vitrified. where do you =
draw the lines. What about the people who stain their "Plastic Porcelain =
Clay Body" Black. How do you discriminate between those who concoct =
their own, those who pay $35 plus for an up market bag of soft clay and =
those who buy the $10 a bag stuff?. What if the items in question have =
not been fired to at least some degree of vitrification as in a raku =
firing?

As Janet says, this is all about concepts of Fair Trading, Liability and =
Common perceptions of what is what. Why not get an opinion from the =
Keepers of Ceramics at the Smithsonian or the Victoria and Albert. Or =
ask auctioneers at Southerbys or Christies for their views. What do F. =
Hamer, Margaret Medley (She gives us the "Purists" definitions) or Peter =
Lane have to say about it.

Think of the sacrifices of Herr Bottger made to achieve what we are now =
able to exploit!
