Well, I do much the same with my scrap, and when I get enough slaking in a 30 gallon tub, I add some vinegar and blunge it until smooth and creamy, and put it in heavy Dacron bags made of
Filter cloth and hang them from the rafters in my studio, where they hang for the two to four days it takes to firm up enough for wedging. I get about 300#s of superb throwing clay from this recycling.
Double bagged, they rest until I need the clay for my next round of making. Best clay ever!
