Anyone seeing this set for
the first time has to agree it bears a strong resemblance to the Jeannette
Four-Piece Measuring Cup Set from the 1930's.? However, there are
at least four differences between the genuine Jeannette set and the new
reproduction set.? Some differences can be spotted immediately; others
will require additional equipment.

First of all, color shade
or opacity is not a reliable indicator of the cup's manufacture date.?
Old cups can vary in shade from light to dark and from translucent to opaque.?
But general quality differences may be easy to spot. In this case not all
of the new cups' handles stood straight out at the side.? New cups
are also about 10 to 20% heavier than old cups.

Next, look at the bottom
of each cup.? The new ones have a pronounced indentation. The older
indentations are shallower and have a thin inner ring that can be felt
with a fingernail.

Now look at the lettering
on each handle.? Old lettering is crisp and round.? New letters
and numerals are larger and appear to have been done freehand.

The final test is foolproof,
but it does require the use of a black light.? Old measuring cups
glow a brilliant yellow-green while new ones do not!
