Hoping someone can confirm whether or not this is Empoli. Found one on google images attributed to Empoli, which was a cased red on white bottle vase, the same shape as this one, but the base was a little different - same small ground pontil in the middle but the rest of the base hasn't been ground flat like this one.
This one appears to be a cased red / yellow (yellow can be seen at the rim).
Flat ground base with concave ground pontil on the centre.
Date?
