Answer:
The coils of clay prevented the pottery from cracking when fired.
Step-by-step explanation:
Pottery is an activity of producing artifact from clay. After being subjected to drying to remove most of the water, the clay is subjected to high temperatures (around 1,000 ° C), which give it rigidity and resistance by melting certain components of the mass and, in some cases, fixing the enamels on the surface. Because of this temperature, it was preferable to make pottery using coils of clay rather than molding by hand, because molding the piece by hand would leave the piece uneven and could cause problems in submitting the temperature.
