Sources here at the library tell that most all American Flint Glass does contain lead, and not flint ironically. The term Flint glass seems to have originated in England in the late seventeenth century in reference to glass made with powdered or calcined flint as a substitute for silica in glass-making which was combined with lead oxide to make fine crystal(Pickvet 84). "In the United states, flints were never used to make glass, but the term made its way here and became accepted referring to any high-quality glass(Shotwell 184). Considering this information, it is very likely that your American Flint glass decanters do contain lead.
Well, we now know that American flint glass really is just lead glass with a different name.
