Recently in Ceramics, we have been working on the construction of coil pots!
Coiled pots are built by gradually stacking and joining coils of clay one on top of the other. The coils can be left visible or can be smoothed away depending on your desired aesthetic end result. It is important that the coils join well during construction to avoid cracking or separation during the drying and firing process.
To avoid cracking or coil separation, the clay must be soft and the proper process to connect the coils together must be used. First, you must score or scrape the clay with a toothpick, then you add a layer of slip.
(Slip is a mixture of clay and water which acts as a glue.)
Students were instructed to smooth out at least one side of their pot. They could use their thumb or index finger to smooth the coils, or use a wooden modeling tool while the clay was still soft.
Soon, they will be bisque fired and ready for glazing! I'll post final product images in about a week.
