Round-Bottom Cups: Comparing Centura & Pyrex 


The Centura cup (left) is very opaque in comparison with the translucent Pyrex cup (right).  The Pyrex cup is thicker as well.

Centura cups with this shape were the first style of cup to appear with Corelle Livingware in 1970.  Corelle hook-handle cups debuted in late 1972 along with Old Town Blue, but it seems that Centura cups were phased out gradually rather than replaced instantaneously.

Butterfly Gold and Winter Frost White Centura cups were discontinued at the end of 1972, but Centura cups in Spring Blossom Green and Snowflake Blue remained in production until the end of 1973.  This probably means that hook-handle cups in Spring Blossom Green and Snowflake Blue were introduced several months later than the other patterns were.

The round-bottom cup style returned in 1981 with the Traditions product line, but this time the material was opal Pyrex.  When hook-handle cups disappeared from the Livingware line in 1982, they were replaced by opal Pyrex round-bottom cups.  Pyrex cups were discontinued in 1986.
