Topic: early/mid or late C19 for sweetmeat?

[Paul S.]

Ex charity shop, so the following are my assumptions only, but I'm getting keen on these sort of things, so would appreciate an experts comments on my learning curve, please.
About 4.5" - 115mm tall - stem sits far from equally on foot - but good central ground/polished concave pontil - which believe phased out (on table ware items) after about 1830 ish - but not certain on this - and superceeded by using the 'gadget'.   The wheel engraved stylized 'fern' decoration is very general C19, and reasonably clear overall colour, with slight grey tone.  Fair amount of manganese presumably (as a decolouriser), in view of the 'green' showing under uv., and am assuming good lead content in view of the very good 'ding' - but understand this not necessarily foolproof test for lead.    One or two small seeds, and noticable are the very symmetrical 'rings', particularly around the upper part of bowl.
Stem is hollow - which think is feature going back to mid C18 - but can't see much info in my books - so bit vague on this point.        So.........sweetmeat, dating to something like 1820 - 1840 perhaps.??
Grateful for anyone's thoughts, and thanks for looking

In view of the hollow stem, I would say it was a champagne coupe. I might also put it later rather than earlier, but I could be wrong.

 The foot is small, attached onto the stem and rounded in a clapper - so I'd guesstimate around 1900-1915.

my thanks to both of you............oh well, back to the drawing board.  But quite a quality piece, so I shall definitely keep, and unless told otherwise will view it as 'possible' champagne coupe - circa late C19 early C20.
