Can you harden natural clay?
Clay that is fired fast must be TOTALLY dry before it hits the steam forming temperature. When firing without a kiln, it may help to pre-dry you clay pieces in a kitchen oven set to 190 degrees F. With a kitchen oven, the pots are dried by “baking” below the boiling temperature of water for several hours.
How is clay made and processed?
Common clay and shale are composed mainly of illite or chlorite, but also may contain kaolin and montmorillonite. For most applications, clays are processed by mechanical methods, such as crushing, grinding, and screening, that do not appreciably alter the chemical or mineralogical properties of the material.

The clay could be at the surface or it could be many feet below the surface, so a place where the river floodplain has cut into is the best place to look for clay. Places such as road cuts or where a steam has cut a deep channel are great places to look because they can expose layers of ancient alluvial deposits.
Is clay easier to dig wet or dry?

The most common handbuilding techniques are pinch pottery, coil building, and slab building.
Can you put non hardening clay in the oven?

How do you harden clay in a microwave?

How do you harden modeling clay without baking?
When you don’t want to cure clays that harden at a specific temperature in the oven, you can use a heat gun, hair dryer or heat-embossing tool set to the desired temperature. Place the polymer clay creation on a nonstick surface, such as a piece of ceramic tile or block of wood.
