storing terra sig

I have terra sig that is years old and doing fine. A few things:

One: I learned to make sig at the Church of Vince Pitelka. I never make
a big enough batch to make the hydrometer process simple, but I pounded
a big cork into the bottom of a narrow piece of pvc pipe and duct taped
it into place -- so I pour my batch in there to measure specific
gravity. When it's just right it looks cool -- does this oil-in-a-puddle
thing on the surface.

Two: I keep a funnel handy, and pour my siphoned, reduced and finished
sig into empty two liter seltzer bottles with the labels peeled off. In
permanent marker I write what kind of clay (I have 3 different locally
dug kinds, plus foundry hill cream and redart) -- the specific gravity,
and a date. I stack them in a cupboard and they don't leak.

Three: I never dip a brush directly into the bottle. I pour small
amounts into a waxed paper cup. The pot (esp. greenware) you are
painting the sig on will offer particles to the brush, and you don't
want to contaminate the big batch. if I have some left over, I add it to
my bottle of decorating slip.

Works for me. I have a bottle I made 5 years ago and it still works
fine. You can see if there is settling because the bottle is clear. Just
give it a good shake.

While I am doing tips: I have small batches of paperclay in the
different clay bodies I use. I put them in those drinkable yogurt
containers, labels peeled off and info written on -- and store them in
the freezer so they don't make the scary toxic mold. They thaw in
minutes in cup of warm water or set next to the wood stove.
