ramanglass544 is right.
They are made here, but not with our Murano glass and not with the traditional technique.
They are lampworked goblets in borosilicate glass, very different from the classic murano softhttp://en.wikipedia.org/wiki/Borosilicate_glass
Due to a very low coefficient of thermal expansion this glass is much easier to be shaped and worked than the "soft" murano glass (very high coefficient).
For these features it is possible to produce also pretty complex and bigger items directly on a flame and not in the traditional furnace.
