Tips:
1. The soft clay will actually harden on the underside faster than the top, because the plaster is soaking up the moisture.
2. Keep an eye on what sorts of clay are going into the mix, as this will influence the firing temperature.
3. This is also a good time to make paperclay!
1. Dry out all your old clay and keep it in a bag for recycling until you are ready.
2. Tip all the dried clay into a bucket and fill up to the top level with water. (Wear a dust mask).
3. Let soak for a few hours (best overnight).
4. The clay should have a soft consistency - slushy that is! Add more water if necessary.
5. If available, mix the soft clay with a drill mixer attachment. (Sometimes available in hardware stores).
6. Tip out the soft clay onto a large plaster bat for drying out.
7. When the bottom half has dried a bit, turn over.
8. When the clay has the right overall consistency, cut up into small chunks and wedge.
9. To homogenize the clay more, cut up and intermix different chunks and wedge again.

It's not totally dry, but too stiff to work with. Use the end of a
broomstick, a wooden spoon, or even a large screwdriver to poke holes in the clay, almost all the way through (leave about an inch at the bottom.) Fill the holes with water. Come back in a day or two and wedge the clay up. It will have absorbed the water and be nice and moist! An alternative method is to cut the clay into slices, soak them in water, then wedge. Or, take a soaking wet towel and wrap the clay with it. Place the whole thing inside the plastic bag. A couple days later, voila! Remember it is important to wedge clay especially when it has been rehydrated, to even out the moist and dry spots. Otherwise you will have difficult throwing, and pieces might warp as they dry.
Stoneware is a mixture of clays used in a manner similar to how they are found in nature, without the addition of stabilizing ingredients.
Place wet, and or dry clay into a bucket and cover with water. Freeze over night. Thaw, pour off water, and wedge when sufficiently dry by using a plaster wedging table or just air dry it.
