I have 2 cups of betonite slurry that I have made by blending 1 pint
of boiling water with 3 tablespoons of betonite powder in a blender
for 3 mintues (as per the directions that arrived with the betonite).
The slurry is now hydrating.

But, I only have 5 gallons of wine I need to fine, and at 2 Tbsps per
gallon, that's only 10 Tbsps out of 2 cups of slurry produced. I was
reluctant to "half" the amounts, as I wasn't sure 1 cup of water would
cover the blades of the blender.

My question is, can I save and resuse the betonite after it has been
hydrated? And if I can, is there any sort of preparation I should
give the betonite slurry when I go to use it again?

Thank you for your help!
