Pattern List - Corning Ware Teapots 

It seems that the 6 cup Corning Ware teapot entered the market in 1960.  An exact date of discontinuance is not known, but since Shadow Iris and Pastel Bouquet are the last patterns to appear on these teapots, they must have disappeared soon after 1986.  Total so far:  19.

6 cup teapots: Strawberry Sunday, Wildflower.

Less numerous are 3 cup teapots which date to at least 1962.  They were probably discontinued between 1970 and 1972.

* - Official pattern name unknown.  Items with a gold-coloured wheat design typically are prefixed with 'W', so these teapots might be marked W-103 & W-104.  This pattern was available in 1969 & 1970, but exact starting and ending dates are not known.

** - With all permutations taken into account, there are actually four distinct versions of the Spice O' Life teapot.  The French phrase, "Le The" may be present or absent, and the main design changed in the mid-1970s also.  The oldest examples have a more leafy appearance, and this aspect was given a trim sometime before 1978.  Comparing the herbs surrounding the edge of the pattern, the newer version has a more compact shape.

In 1971 four special 6 cup teapots were available, called the "Garden of Teapots".  The patterns were designed by Alice Kiernan, who was also one of the designers of Spice O' Life (1972).  The Garden of Teapots includes: Bantry, Canterbury, Chelsea, Lancaster.  Original packaging also dubbed these a "Partea Teapot".

Other Teapots:   

A newer style is the 8 cup Designer Teapot, a P-168.  The pot itself is undecorated, but the lid and band are solid-coloured.  There were four to choose from:  Chocolate, Lemon, Cranberry, Blueberry.  This type was introduced in 1983, and it was last available in 1985.

The shape of the P-210 is very similar to the P-168, and it was made from 1983 to 1985 as well.  But the P-210 was not meant to be a teapot, it was designed as a universal replacement carafe for all the major brands of automatic drip coffeemakers.  It holds 10 cups and it was available in plain white only.

2 Quart Teapot (P-105), 4 cup Beverage Server.

Two Quart teapots were available in Blue Cornflower and plain White.  Beverage Servers in 4 cup and 8 cup sizes were introduced in 1965.  These also came in Blue Cornflower and plain White.  Like teapots, Beverage Servers came with no special parts or attachments and were meant for tea, instant coffee, hot chocolate, etc.
                        
Other shapes and sizes of teapots exist, but some pieces believed to be teapots are actually filter-drip coffee makers.  A good example of this type is the P-106 from the mid 1970s.  These came with a large plastic cone which held the paper filter and coffee grounds; it would stand on top of the pot while boiling water was poured in.  The lids for these coffee pots are similar in style to teapot lids.

The Merry Mushrooms product line was a Sears exclusive from 1970 to 1986.  Different manufacturers supplied various types of products with this pattern, and Corning Ware cookware was one of them.  It first appeared in 1975 and might have been available for only a short time.  On packaging, backstamps and in catalogues the various collectibles were named Merry Mushrooms, but the original boxes for Corning Ware carry the pattern name Merry Mushroom.
