Quite a bit more porous according to our testing data. So much so that it
will become contaminated easily during use and could very well become a
health hazard.
Also it will be a problem in the microwave - filling with water over time
and the result will be hot handles for instance.
I don't think paper clay is the right thing for dinnerware at all - if you
want to do some testing I can help with that.

With the exception of a slightly more porous nature, it is almost as dense
as regular caly, and retains all of its original strength. The sound is as
legitimate as regularly made stoneware.
The greenware state is stronger because o the fiber in the clay. Cutting it
or arving in it requires really sharp tools, though. Plain metal edges wont
do.
Also, the fact that the fibers wake up and swell into the clay added to the
dry ware is what makes it all stick together so well. You can repair chacks
on bisqued ware with fresh p-clay and re-fire it. I was amazed at its
flexibility.
Further, it is made in several types of clay, and can be custom ordered in
large batches if you have a specific clay you want in the p-clay formula.
Axner is the one who carried it with the originator of the product. In fact,
they work with her in formulating anything in p-clay.
The dry sheets can be assembledAfter they have completely dried, and can be
cut with a hacksaw, like wood.
Sort of interesting techniques, I think, for something we are not used to
working like that.
Please let me know what you think about it! I would be interested in
knkowing how it changes your approach to building.

You offered me ron to change the glaze a bit yet I like it the way it is kind of yellowish
When I want totally clear liner I use yours gloss liner.
I made a paperclay, I tested for "collapsing", it passed fine
I made a bar according to your explanations;
Hot from the kiln was156.5 grams. After cooking for two hours was166 gram. And I
wander who I can remember these numbers and forget the number of my mobile
phone!
Well, it was not clear: Do I multiply 166 X 156.5 divide to 100? or plus or minus?
I made some cups, I test the glaze

That I know it is good to see how behaves on this claybody.
I have a story i shall send it in a different mail
I think , about microwave that this is ( like pornography a matter of geography: When I
sold some mugs lately I said they were tested for dishwasher freeze heat and so on,
yet I said were not tested for microwave: The costumers said surprised ? Microwave
who put ceramic dish in a microwave?
In a separate letter I will write about this too might help Israeli clayarters.
