Use plastic wrap instead of canvas. Flatten the clay between your palms, then lay it between two sheets of plastic wrap. Roll with a rolling pin, being careful that no wrinkles develop in the plastic. Rotate and roll out again, repeating this sequence until the clay is as thin as you desire.

Why do we wedge clay?

The general idea includes throwing down the clay and rolling it into a tight spiral with a sort of kneading method. Wedging makes the clay more pliable, ensures a uniform consistency, and removes air pockets as well as small hard spots in the clay before you use or reuse the clay for a project.

Can you use unglazed pottery?

I'm very new to pottery, but from what I know unglazed clay is super porous and soaks up liquids like a sponge. You really should not use them for eating. They're also kind of dusty, so if you tried to eat from it you'd be eating particles of clay every time.

What are glazes made of?

Glazes consist of silica, fluxes and aluminum oxide. Silica is the structural material for the glaze and if you heat it high enough it can turn to glass. Its melting temperature is too high for ceramic kilns, so silica is combined with fluxes, substances that prevent oxidation, to lower the melting point.

How do you make a slip?

The process of slaking clay to make it into slip is a simple one. Step one is to have a 5-gallon bucket filled 60-75% with your bone-dry clay then add water until it's a few inches below the rim (figure 1). Let it slake for 24 hours then mix it by hand a little with a stick (figure 2).

Where did coil pottery originate?

Coil pottery originated in Central Mexico nearly 4000 years ago and slowly spread north, and I mean slooooooowly. It took nearly 2000 years for coil pottery technology to travel to the area around Tucson, Arizona where the earliest pottery in the United States has been found.
