Coiling is a hand building technique used to make pots. Plastic 'snakes' of clay are used. They can vary from a thin strip to a large sausage like strip. It is hand manipulated, pinched and squashed together to form a pot without the coil like look from how it was started, though in some cases the clay can be left snakelike for the decorative look. Typically this is started at the base of the pot and built upwards.
