This is my set of five harlequin glass coffee cups. I assume there were six in the set originally. The green and yellow ones glow strongly under UV, the others glow a little bit around the thicker parts. They are hand blown with ground pontils and the handles are all slightly different. Maker unknown. Also shown is a "Mary Gregory" vase and two Anchor Hocking Royal Ruby posy vases.

These little coffee cups are normally called coffee cans. You might be able to do a more refined search using that term.
Any faint green glow with UV will be from the manganese decolourant often used - and general dust and muck glows a little green too.
For Uranium, the glow needs to be very bright and still show when your UV source is a good bit away - Christine recommended the "6 feet test" to me.
Jay provided a link to this site of his in another thread recently. It might be worth your while digging around here for harlequin sets. :)

I have heard there are two sorts of "Mary Gregory" - older and newer. The older stuff has childern who are much plumper than the newer stuff. Slim children indicates newer.

I did try entering vintage glass coffee cans and what I got was vintage coffee tins!

Did you try using some inverted commas to help out?
It can be a real pain sifting through the chaff. ::)
Do dig around that site I linked to - there were a few Belgian companies making Harlequin sets.
