Here we have a picture of a Medieval cooking pot form Sicily. Through petrographic analysis we could reconstruct its forming technique. The picture taken with a petrographic microscope shows the circular alignment of the rock inclusions (the colourful elements in the brown background) which indicates that the pan was formed with the artisan's hands, using a coiling technique, not on the potter's wheel. This technique can still be employed today in the creation of functional cooking pots.
