happy new year to all the clayarters.
i bought a bag 50lbs. of plaster and want to do some small molds. what is the correct way to store the remaining plaster. will it be ok to put the remainder in a plastic storage box the kind one uses for sweaters, etc, or should i put it in plastic gallon jars with covers. i think that i won't be using the rest for several months and would prefer to keep it in good condition.
thanks for your help.

I put a 100 pound bag of plaster in a big garbage bag and stored it
for years in Montana. I was fine every time I used it. But Montana's
humidity is usually single digits. I made big molds and small ones
for several years.

Eleanor, the key to keeping your plaster fresh is keeping it
moisture free. This includes atmospheric moisture if you live in an area
with much humidity. If the plaster is exposed to atmoshperic moisture
for a prolonged period of weeks and/or months it will react with the
water in the air and become "seeded." This is the condition where there
are little seeds of plaster rather than a fine powder. If this condition
occurs just save yourself a load of trouble and toss the plaster. For as
moisture free storage as you can get double bag you plaster in large
plastic bags and seal the whole thing with tape. Then try and keep the
plaster in an area where you won't get a lot of temperature swings that
could lead to condensation.
Alternatively, you could use a good five gallon bucket, or two, with
nice tight fitting lids. After you have filled the bucket and applied
the lid, a round of duct tape at the lids lip sealing it to the side of
the bucket will keeps things nice and fresh. If you decide to go this
route make sure that the lids fit correctly.
Hope this helps

Store it in air tight containers.
Plaster does have a shelf life and will absorb moisture.

Unless you only have little, gallon jars
seem a bit inefficient. I like the plastic
storage bins or buckets, but use a sturdy
trash bag for a liner and close it tightly.

Hydroscopic....plaster absorbs moisture from the air and humidity. Plaster=
will not last forever...after 6 months forget it. buy some new stock. N=

tables. Keep it as dry as you can for 6 months...then if not used...toss it=

There has been a lot of talk about old plaster and throwing it out. Does
anyone know of any uses for "old plaster" other than sending it to the
landfill? For example, can it be used as a calcium addition to garden
soil?

A handful at time in a two gallon bucket of water, mixed well so that it =
is not allowed to set, is great for a garden with sticky clay earth. =
Helps to flocculate the clay.

I also successfully store my bags of plaster by carefully sealing them in
those heavy black plastic bags and taping up. I do this as soon as I bring
them home, not just after I open one.

I HOPE plaster lasts for awhile. I have a 50lb bag here that's been
here at least 3 years, and never opened....and now, of course, I have
some plans for it, dadgum that Paul Wandless anyway for writing his book
and giving me YET ANOTHER thing to experiment with!!! I will
never live long enough to try all the ideas I've ever had or seen
...
