Many thanks for that . Really interesting.  I think I might try storing potatoes in it.  The lid isn't airtight, so should be okay.  I have a problem storing them.  After a week in a dark corner of the garage, they start sprouting which is really annoying and costly!  So I'll see if the pot works for them.  I've got another smaller stoneware salt glaze pot with handles in the garden with succulents growing in it.  I never drilled a hole in the bottom, but the succulents don't seem to mind and they come up every year without fail.

A milking stool sounds like a good idea.  The turning on the top would make it more stable to sit on as you would be unlikely to slide off.  Kind of like a textured surface with grip.

Hi Anne, I used to have one of these without the lid - in fact I may still have it in the garden somewhere!  I was told they were used to preserve eggs in isinglass before fridges. I don't recall mine having a stamp on it though it looks the same shape and handles etc.

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

It's more furniture than treen but we don't have a furniture forum so it's fine here Daniel.  Could it be a milking stool?
