Can you add clay to bone dry clay?
Also, the bone dry clay sucks all the moisture out of the slip very rapidly. As such slip won’t stay liquid and doesn’t create the liquid soup for clay particles to move about in. So, generally slip is not used to join pieces of bone dry clay.
What happens if you wet dry clay?
Wet clay contains a large amount of water, a minimum of 25%, actually. When clay starts to dry, water evaporates from it. As this happens, the particles of clay are drawn closer together resulting in shrinkage. Porcelain clay has very fine particle sizes which makes it very plastic and also shrinks the most.
Can you add onto dry clay?

Can you add wet clay to bone dry?
Unknowing, forgetful or pig-headed beginners may be able to join a wet piece of clay to a near bone-dry piece (typically something they have been working on for days and have let dry out too much), but in the end, no matter what they do, the wet clay will shrink more than the drier clay and all their effort will.
What does it take to smooth out regular clay?
No matter how much you try to smooth out the clay when it’s wet, sanding is inevitable. I start with medium sandpaper (60-120 grit) to polish rougher areas and remove larger bumps in the clay, then I move on to fine (160-240 grit) and super fine (400-800 grit) sanding papers to polish the clay.

How do you seal air dry clay pots?

Do you paint air dry clay before or after it dries?
Air drying clay does not react with water in the same was as kiln firing clay and once it has hardened it cannot be returned to a workable state. Clay needs to be left to dry completely before painting, the length of time it takes will depend on the size and thickness of your project, usually between 24-72 hours.
