Hi Betty,
Thanks for the info below.
I am in the throws of many projects right now, including first firing of OLD
kiln..very exciting.

The paper clay I made has only about 20 procent pulp in. Therefore I expect=
it not to be
as porous as your portions. It is so WET that it has been slaked out on a
plaster slab for a week
now with little signs of drying=21 I will get it wedged up hopefully soon =
give it a try on the wheel, as I mostly throw. Just the properties of this
clay make me want to try handbuilding with it, so I am thinking about some
simple hump moulds to begin. I will hopefully soon be able to post =
findings if
the weather warms up and helps dry out this paperclay I am waiting on.

Many thanks,
Alisa in Denmark (cold like in New York)


As I mentioned in my last response about paperclay, I am new to this
process also. But I have tried both toilet paper and cellulose insulation
for the paperpulp and liked the cellulose insulation much better. The
cellulose did not break down as much as the toilet paper did (in the
paperpulp-making process) and therefore made the paperclay more porous. If
you are trying to throw with the paperclay this would not be an advantage.
But for pressing into plaster molds, it was great. I was on a marathon
hand-making kick and could pop the clay out of the plaster hand molds
within 24 hours after pressing the paperclay into the molds. Also,
repairing broken fingers on the paperclay hands was much easier when the
clay was made with the cellulose. I also had more cracking (at stress
points) when I used the toilet paper paperclay, and both wet and dry
repairs were much more difficult with the toilet paper paperclay. I also
like the textured look of the cellulose paperclay. I used between 30 and
40=25 paper, by volume, in both paperclays.

So there you have it, my biased opinion.

Hope I was of some help.
