I have a book The Arthur Negus Guide to British Glass which is full of tips on what to look for and identify stem ware.
During the early years of the nineteenth century a characteristic mark found on the underside on the glass is a Y or T impressed into a flat foot with no sign of a pontil mark. This was caused by a springloaded instrument called a "gadget"

Crumbs, I have to disagree with Arthur Negus! :shock: :shock: I've just read about gadgets you see...
The apparent letters K, I, Y or C that can be found on the underside of a foot are caused by the shears when the glassmaker cuts off the required amount. A cold, hard ridge is left where the shears cut the glass. It doesn't melt away, but forms various shapes as the gob is tooled to create the foot. (Cribbed from Glass Circle magazine No.103)
A gadget mark can leave two parallel lines indenting the upper surface of the foot (quite close together and running towards the stem), as the top of the gadget is a C shape that clips over the foot. I seem to remember Ed Iglehart using one at Art in Action.
Hmm...I only said to Peter yesterday that I didn't think I'd learned much this year...maybe something trickled in somewhere :lol: :shock:
