<< If you squeeze out as much of the water as possible, put the pulp in a
plastic bag, and freeze it. (I have kept it up to a year.) It dose take
up space in the freezer. When you want to use it again, defrost and
add water. My paper pulp has been made out of recycled paper and paper
with fibrous plants and cuttings. >>
Or, because I do not have an ounce of extra space in my freezer, you can dry
the pulp out. Just like Sue suggests, squeeze out as much water as you can
forming it in the shape of a baseball. Set the ball of pulp in a sunny
window for a day or two turning it every once in a while. Make sure it is
totally dried out before storing them in a paper bag or it will mold.
Here is an interesting story about saving the pulp this way: Last year, after
finishing up a series of classes, I just shoved all my papermaking making
supplies in my garage meaning to clean everything up the next morning. Well,
of course a week or so goes by--time for another class and I still haven't
cleaned it all up. So I hurry and pack everything together for the class
figuring I will sort it all out before the students get there. Much to my
surprise as I unpacked my pulp "baseballs" i noticed a small forest growing.
The previous class had added all sorts of seeds to the slurries. Some of the
plants growing out of the pulp were a good 5" long. It was quite remarkable!
(This could make a pretty cool tangent lesson off of papermaking!)
