Charming vintage 1940's/1950's Pyrex Primary 3pc nesting mixing bowl set! Colorful mixing set includes large 1950's yellow 404 • 4QT bowl and late 1940's green 403 2-1/2 QT bowl and red 402 1-1/2QT bowl! These 2 early Pyrex bowls do not have the numbers on them, as they are the
first set made before the production numbers were in use, but are the
same standard sizes. These older pieces are a lovely thick, heavy glass. Washing care: we always recommend a mild soap and warm water clean up to help preserve
their color. If you haven't started collecting Pyrex, this may be your
set to start your collection or a fantastic addition to your established
pieces. * Due to the heavy weight of this set (over 7lbs combined) we
are happy to offer several courier options to save on shipping costs!
Proclaimed as the “World’s most famous mixing bowl set,” the primary colors set was the first of the Pyrex items produced on white opal ware
with colored overlay. The new Pyrex opal ware line was a result of a collaborative effort
between Corning Glass Works and the United States government to create a
sturdy, lightweight and unbreakable dish for soldiers during World War
II. A 1946 Ladies’ Home Journal advertisement touted the new
opal ware bowls as “2 oe times as strong as ordinary bowls” & “Heat
resistant for oven use,” and used “For mixing, baking, serving and
storing.” Originally released with a more defined foot the bottom of the bowls was
redesigned in 1950, creating the version of Pyrex opal ware bowls with
which we are now familiar.
