I dig this out every so often but never really succeed with a date or country.
The rim may well be spun initially, and then hot-processed on a former to create the slump shape/wave, and it could be that the cut blazes hide any marks picked up from the mould - some very slight marks on the uncut peaks.
All of the decoration is shallow cut (including the cog-wheel effect on the underside of the foot), and there's a high quality very symmetrical large polished depression under the base.
I've had it down as late C19 - sort of art nouveau/secessionist/arts and crafts - could be Continental or British, but not really sure.
Quite a high pitched ring (slightly W/F's ish). Appreciate that a maker is probably out of the question, but maybe a date and country is a possibility.
Height is about 5.75" (145 mm), and about 9.75" (250mm) at the rim.
Would be very interested in any thoughts or opinions, and thanks for looking.
