Is this some food/drink related vessel for storing, what ever, vine, oil, schnaps, pickled something.... or simply just a large vase?
It seems quite large for a vase with 46 cm height, 25 cm largest diameter. Base d-12cm, neck/lip opening 7,5cm and 14,5 across the lip.
Was there ever a lid, if it is not a vase? It has four vertical lines on the body from the middle of the "neck" towards the base arranged in such a way that if the mould was used for making it (probably?), there where two wider and two narrower moulds. Neck/lip section is again separated from the rest of the body with horizontal line around the neck.
Blow moulded in the second part of the 19th century handle-less glass amphora
