hobby craft has a range of clay, air hardening and normal. I'm guessing all arts and crafts shops should have clay.

Clay is pretty waterproof already, but to make it truly so, dry it and bake a glaze on it inside and out.

by bisk firing clay and then glazing it and firing it again, the clay will become waterproof. the clay hardens and the glaze (once heated)and becomes just like glass covering the outside of the clay.

A high fired clay pot is waterproof and a glazed pot is waterproof and both are safe for this purpose.

Some types of air beds (such as the ones used for camping) are waterproof. Intex is a brand that carries a lot of waterproof air beds.

Only if you go over it with a special gloss.

A microwave is not a good choice for hardening clay. A conventional oven at a very low temperature is better.

Not exactly, water for modeling clay uses it to make it more moist but if you drop it in a pool, it will get sticky and gooey

you buy air dry clay and it drys in 10 secs by air

air bubbles are stuck in the clay

no. you put it in the oven. :)

i don't know clay soil lack air and water

The process of removing air bubbles from clay is called "wedging."

There is air drying clay...

You don't bake air dry clay...so, no problem!

shale is smooth and it is formed by hardening of clay so it is used to make bricks,tiles,plastics,cement etc.

yes'hot glue is a waterproof substance it is air-proof and very efficient. Can someone answer if hot glue is biodegradable?

it depends what clay you are using, air dry clay drys by its self if you leave it on the window sill it will dry, for normal clay you bake it in a special clay oven.

Clay can contain air bubbles which contain water. When the clay is fired, the heat rapidly expands that water vapor, causing the piece to explode. Therefore, clay pieces should be hollow, with a hole for expanding air and water to escape.

Yes put them in a plastic bag.

Air dry or kiln depending on the clay type

you can with polymer clay but not with air dry or other kinds

It can be if you just believe it can. Magical mind powers.

A properly designed sanitary landfill system is built of many layers. Starting from the top (for a finished site) there are:An aesthetic layer of soil with grasses anf bushesAn impervious compacted clay layerA layer of trash and wasteA clay layer to protect the waterproof membraneA protective waterproof membraneAn impervious compacted clay layerA system of under-drainsThe native (undisturbed) soil

Add water. If you can, poke holes in it so the water can really soak. Wrapping it in a plastic bag will also prevent it from hardening so quickly.
