The best plasticity is created when the clay is hydrated the most,
so if you dry out trimmings and slake them as a slurry, then dry the slurry to useable
consistency, you've created about as much plasticity as you can get. I remember
Pete Pinnell saying, " 99% of aging is getting the clay completely wet to begin with."
This is particularly important with porcelain, where the clays used, kaolins, aren't
particularly plastic in comparison to stoneware and ball clays, and even fire clays,
used in stoneware bodies.

I recently found an old bag of dry porcelain, hydrated it and made it
usable. I fell in love with it and went to buy more, and realized how
important plasticity is! Does anyone know how to age porcelain, and in my
lifetime? Any suggestions are greatly appreciated.
Thanks

Hi Claudia,
Aging is no secret process. Just put the wedged clay away somewhere,
well wrapped in plastic bags, and wait. A few weeks makes a big
improvement. A slightly warm place helps speed it up. I usually make it
up a little soft, then it firms up over the weeks or months of aging.
Was your old dry Porcelain bone dry, or only too stiff? It sounds like
you made up a slop and then dried it down to a workable state. That's
the way to get maximum plasticity out of clay. Slop mixing gets every
particle thoroughly wet, then you dewater it somehow.
Happy mixing,
