I do love uranium glass, esp in the form of a leech pot. Under UV light:
Until I recently bought the pot bottom right which is mould-blown, all the leech pots I owned were free-blown. In normal light:
Group of uranium pots in size comparison with cobalt blue and clear pots:
All the pots are roughly the same size, 5.5 to 6.5 cm.
That green pot above looks like a leech pot without the flat rim. I wonder if it started life as a leech pot and got converted to a little posy bowl.

I thought this wonky leech pot (below) might react under UV light but it doesn't.
I'm fascinated by ordinary household glass from the 18th and 19th centuries, such as lamps, leech pots and vases. Most reference books about glass seem to ignore these categories in favour of fancy expensive drinking glasses.
Even functional household glass was decorated to be a pleasant addition to the home. The distinctive flat rims allowing a cover to be tied on (to prevent the leeches escaping) and the scratches on the inside of the bowl from use.
These fern-engraved leech pots on pedestals vary in height from just under 8 cm tall to just over 8.5 cm.
Leech pots engraved with the popular Victorian fern design.
These are two of them close-up.
18th century leech pots, larger than the other "small" ones, are 10 and 9.5 cm tall

The size range of glass leech pots, from left below, large probably for a chemist shop, an 18th century handblown pot, last two, small for the home.
All the following small leech pots are about the same size, ranging from 5.5 to 6.5 cm tall
clear leech pots

This clear leech pot is a bit larger. It's 8 cm tall and has polished pontil mark on the base (will add photo).

Cranberry was obviously a popular colour for leech pots. these range from 5.5 cm tall to 6.5 cm tall
These are all hand-blown with snapped off pontil marks, except the one on the far left whose pontil mark has been polished.
This amber leech pot has a delightfully handmade look - well they all do! but this one isn't even properly round. 5.5 cm tall
Cobalt Blue Leech Pots (includes one shown above), both about 6 cm
Teal Leech Pots, both just over 6 cm
teal leech pots bases, rough snapped off pontil marks
this greenish leech pot has an unusually large rim
Ribbed Leech Pots
Blue ribbed leech pot, just over 6 cm tall
although this blue leech pot looks like the rim and just under it should glow under UV light it does not

The Old Operating Theatre museum at St Thomas' Hospital has some leech jars/pots in its collection:
This leech pot is from Guy Gaboriau's book, Outils de la sante et medecine d'autrefois, a great book about medical antiques.

pounce (or sand) could be sprinkled on a letter to help dry the ink
(all my pics look better with a cat! in this case, Socks)
beautiful faceted glass, sadly with some chips around the base
one is slightly smaller than the other and also slightly darker in colour
this pic I know is way too dark, will add another shortly
