The list of vintage Pyrex made in the Regency/Heinz green color continues to grow.  Most recently discovered is the 232 Utility Baking dish.  While no official paperwork has been uncovered, one theory is that this bakeware series was produced to complement the Regency tableware pattern released in the 1950s.  This shade of green is also found on the Heinz promotional dish, so it is unclear what the official name of this color should be.  Whatever the name, this series includes 015 + 025 Hostess Bowls (015 with clear glass lid, 025 with solid lid), 024 round casserole, 221 cake pan, 232 utility dish, and unmarked mini bowls.  One shape that has not surfaced yet, but would fit into the bakeware line, is the standard 209 pie plate.  Since new pieces in this color keep popping up, there is no telling how many more shapes and sizes were produced in this color!  Kind of exciting, right?
