Spotted this yesterday and had to have it although I haven't a clue what to do with it. I think its salt glaze stoneware. 10" high(excluding the thick wooden lid with inverted handles) and really heavy weighing 5kg. I'm not sure what it might have been originally used for.. The inside has a shiny glaze, so presumably for dried foodstuffs?
Fortunately there is a maker's mark which looks like "jemmy" along with the number 7. I'm not sure what the significance of the number is. Perhaps something to do with capacity, or may be just size 7.
I've searched variations of "jemmy" but can't find a thing. Does it ring a bell with anyone? It looks to be quite old, and possibly Continental.
TIA
