Rustically handmade with local clay, each of these confit pots is unique.
With a wide neck to easily fill it with the food to be preserved, each French home would have had a selection of these to store food through the winter, the handle to hold the slippery pot firmly when it was being filled and then the contents used. 
This pot measures 10cm or 4" diameter at the lip and high.
