The state that the clay will be in is call BONE DRY, pieces are very fragile and brittle in this state. Clay fired in a kiln fires at 2000 F + so your household oven will not produce the same result as a kiln.

We grabbed about 20 lbs of clay off a dune in Wellfleet Mass yesterday and plan to mold it into some fun things. Can they be dried in a conventional oven (we don't plan to glaze the objects) ?

That's not hot enough to melt a food safe glaze. It *is* hot enough to melt some glazes, but they'll generally contain a toxic metal or two. Also, if the glaze melts in your oven for the initial cure... it's likely to melt in later use. Not cool. Most cities have businesses that sell kiln time. If you poke around, you should be able to find one. They'll usually be quite helpful about things like selecting food safe glazes and paints, and you can often get studio time there as well.
