Matthew,
Make sure your pottery walls and bases are of even thickness (cut a few in
half after throwing). Dry slowly. (Cover with plastic if necessary.) If all
else fails, change your clay. Some clays are more crack resistant than
others.

Hi Matthew,
Try keeping things under plastic and out of drafts for a longer period of
time to dry things very slowly. If the cracks are at the bottom of a wheel
thrown bowl and in the shape of an s it is called an s crack and is due to
not compressing the clay good enough when throwing. Handbuilding cracks at
the seams come from not making the joins strong enghough.
Where are the cracks?

Matthew,
Cracking occurs most of the time due to rapid drying. Don't know what you
are making, but if one part of the piece is thicker than another, the thinner
area will dry faster and shrink at a faster rate causing a crack. Rule of
thumb: dry the piece up side down, dry slowly and pray over it.

Hello Matthew Zehr!
Where I live, one day can be cold and the other very hot, especially in this
season.works, that dry too fast suffer from the problem you write about.
To avoid it: 1)When your dry your work on a plywood, or anything like it,
put in between a piece of paper-This way the bottom is separated from the
wood and dries evenly.
2)Plastic bag cover slightly, gives it air but delays
drying.

Hi Mathhew,
I recommend the Potters Dictionary of Materials & Techniques by Frank and
Janet Hamer. A little pricey but - find the crack that looks like yours and
the explanation about how it happened will help a lot. The crack section is
8 pages long.
