Topic: Round fern engraved glass, for what ?

[keith]

It's the history of pieces like this that interests me, who used it, where has it been all these years, lace makers lamp is also on my list of things to find

love a man with ambition   -  Wilkinson says ...  "lacemakers' lamps can form a complete collection on their own ........"                  .........   part of the problem/fun would seem to be recognizing them when you see one.           Then there's the long necked water-filled globes that are suspended in front of the lamp (to amplify the luminosity) -  the glass lace or linen-dabbers - and the glass water sprinklers, but agree the history is so appealing.
There is some pteridomania (fern related) engraving on this leech pot, too.

I see on Wikipedia “Leech therapy was classified by the US Food and Drug Administration as a medical device in 2004“

I think that calling leeches 'devices' is discriminatory - but nothing surprises me from that side of the pond.
