I purchased a bunch of these individually  made and featuring different patterns when I was recently in Sorrento Italy on a sourcing trip. These are 18th to early 19th Century butter molds made by monks. They are made of earthenware or stoneware pottery material. Nubby feet and this one has the Italian word Charitas impressed along with a flower.  The word Charitas means loosely Charity. This is 5" by 4" wide and about 1" deep. See images showing few hairline cracks, few sections on the rims with missed glaze. These can be used for decor, wall hanging, soap dish etc. So many great uses! Catch all trinket holder etc. Knowing they were made by monks and sourced in Sorrento Italy at a lovely antique store just warms my heart!
