type of clay and colour six letters
It will really depend on the type of clay that you have. Some non drying clays may become hardened if you bake it. However if it is modeling clay it will be impossible to dry it.
I have no clue, I suggest you buy another brand.
pottery pieces crack during drying because the clay shrinks too fast and unevenly. If drying is controlled by wrapping pieces in plastic and allowing them to dry slowly, they won't crack usually.
Are you asking what kind of clay types there are? What can you make with clay? or what different processes there are for firing the clay?
Both types of clay are the same. You can use both types of clay to create things. I looked into this and found out that both dry up after a while if you want it to. If you want to paint the clay after it is dry is sort of a mystery to me. I absolutely know that after the crayola air dry clay drys you can definitely paint it. With other types of modeling clay, I am not so sure. I hope this helps.
There is air drying clay...
You can clean dust and dirt from a polymer clay sculpture that has been painted with acrylic paints by rinsing it under warm water and drying it off with a towel or paper towel.
Normally you would buy it. Craft shops sell various types of clay. Alternativly if you live in the right area you can dig it out the ground. However this clay usually needs to be prepared by drying, crushing, sieving, reducing to slip and partial drying on a plater batt before it is ready to mould.

It is painted after.

Some types of air drying clay can be fired. A few air drying clays are normal water based clay bodies to which nylon fibres have been added (eg. Neclay and Potclays Creative Clay). These can be fired burning out the fibre in the process but bear in mind air pockets in the clay may cause the piece to explode in the kiln. Another alternative would be to make a mould from the air dried model and cast one or more permanent pieces from this mould either in resin or plaster of Paris. If you have a kiln it would be far safer to make a plaster of Paris mould from the air drying master and then slip cast hollow clay copies in a clay slip that you have the firing data for.
spray and drum drying and a combo of both
his dad painted signs for stores.

It should have baking or air drying instructions on the packet.
