Glassware

The difficulty in identifying glassware is that it often has no definite logo or backstamp, making it harder to name the manufacturer.  Perhaps this is of no consequence, as Corning was never the manufacturer of Corelle-matching glasses.  Even official glassware has always been manufactured by a third-party company, and made from ordinary glass.  Although the Corelle brand name might be on the box, the glasses are not made of break-resistant glass.

In determining which glassware is official, the best option is to study the pattern and compare it to a real piece of Corelle.  If every aspect of the design looks absolutely right, it might be a licensed product.  In any case, if the butterflies look a bit odd, or not all the blossoms are represented, or there aren't enough dots between the snowflakes, it is probably a look-alike.

 

Libbey:

Libbey is the most noteworthy producer of glassware that matches early Corelle patterns.  It is not clear whether every single one of their products of the 1970s was made with permission.  There are examples of Libbey glasses that are licensed Corelle Coordinates, but there are many older ones with look-alike patterns in diverse styles and designs.  

Small Wildflower glasses from LibbeyLibbey imitated Snowflake Blue, Butterfly Gold (some in amber glass), Spring Blossom Green (some in green glass) and Old Town Blue.  It seems that this company made official glassware in these patterns too, plus Morning Blue.  There are Meadow, Indian Summer, Wildflower, Strawberry Sunday, Country Festival and Spice O' Life glasses by Libbey too, but these designs seem to be look-alikes.

Libbey glasses: butterfly gold and spice o' life designs
Libbey Glasses:  This Butterfly Gold version has a coloured rim, and the Spice O' Life version is inscribed with "Bonne Sante".

There are also closed-handle pitchers, beverage jugs and cork-top storage jars that appear to be made by Libbey with look-alike designs.  These include Butterfly Gold, Spring Blossom Green, Country Festival and Spice O' Life.  Determining which pitchers are Pyrex and which are made by Libbey is fairly simple.  Pyrex pitchers always have "Pyrex" printed on the side as part of the decoration, and they are very thin, lightweight and fragile, like laboratory glass.  Conversely, Libbey pitchers are thicker and more hefty.

Newer Coordinates patterns are too numerous to mention.  Most patterns from the 1980s & 1990s include matching glassware, the majority having the distinctive "single bulge" shape near the base, but others have a thick heavy base and straight-sided shape.  Libbey also made beverage jugs in selected patterns for the Corelle Coordinates line.  
          
Libbey - St Clair logoLibbey logo.Some licensed Libbey glassware is marked with the word "Crisa".  Crisa is a Mexico based subsidiary of Libbey Inc.  Some, but not all of Libbey's products are marked with an "L" logo (shown at right).  Canadian-made Libbey glasses are often marked with the Libbey St-Clair logo instead (shown at left).

James Bradley Assoc. (Glassmates):

Products from James Bradley Associates, of Northridge California, are easier to identify.  Most items are marked with "1973 James Bradley Assoc Inc", but some are dated 1974.  The brand was called Glassmates, but this name only appears on packaging.  It seems that JBA was not a glassmaker at all, and was only in the business of decorating blank glassware manufactured by other companies.

Patterns imitated by JBA are: Butterfly Gold, Snowflake Blue, Spring Blossom Green, Old Town Blue and Spice O' Life.  Glassware sets were offered in clear glass, as well as with a white exterior finish.

Beverage jugs also were available and they have a similar narrow-necked shape as those made of Pyrex.  The difference is easily spotted though with the white exterior finish on JBA versions.

Also part of the Glassmates brand were pedestal mugs in white opal glass, with decorations imitating: Snowflake Blue, Butterfly Gold, Spring Blossom Green, Old Town Blue, Woodland Brown, April, Blue Heather, Indian Summer, Meadow, Spice O' Life.  The mugs were manufactured by Federal Glass and a few have Federal's logo on the bottom, an "F" within a shield.  But most mugs have no maker's mark at all, but their distinctive "B" shaped handle identifies them.

Besides glassware, JBA also put their name on vinyl placemats.  So far only a "Butterfly Gold" version is known, bearing a 1972 date.  The pattern is not very convincing and does not match the glassware designs that this company produced either.

 

Indiana Glass:

Morning Blue, from Indiana GlassFrom early 1986 to mid 1992 Indiana Glass held a licence from Corning to produce matching glassware under the "Drinkware for Corelle" brand.  One style of glass from this company is recognizable by the "double bulge" near the bottom, and exists in the following patterns, but there might be more too:

Apricot Grove
Black Orchid
Blue Lily
Country Violets
First Of Spring
Forever Yours
Morning Blue
Silk & Roses
Symphony

After losing the Corning licence, Indiana launched the "Complements" brand based on look-alike Corelle patterns.  Imitations of Forever Yours, English Breakfast, First of Spring and Apricot Grove exist with the double-bulge style.  There are other items, like candy dishes, made with this version of Forever Yours.

 

Old Orchard glasses from Dominion GlassDominion Glass:

This Canadian manufacturer made glasses to go with Spice O' Life, Country Festival and Old Orchard.  Glassware from this company is generally marked with a capital "D" logo. 

(Photo: Old Orchard glasses.)

Spice O' Life glasses have a look-alike pattern, and their shape is similar to Libbey's single bulge style.  But the printed design is quite different from that of Libbey glasses and the French phrase is absent.  The Country Festival version can be found on glasses as well as salt & pepper shakers.  Glasses matching Old Orchard seem to be a perfect match, but it is unclear whether they are a licensed product.

Unknowns:  Glassware from unidentified makers with authentic-looking patterns.

Morning Blue with an hour-glass shapeOne notable glassware shape can be found in Butterfly Gold, Old Town Blue, Morning Blue, Ribbon Bouquet, Blue Floral and Blue Lily.  In two sizes, it has a slight hour-glass shape, narrowest in the middle and flared top and bottom.  The base is flat and thin.

(Photo: Morning Blue with an hour-glass shape.)

Another style that might be related also has a flat base, but the sides are completely straight.  This type exists in practically the same variety of patterns as above.

Woodland Brown glassware was also produced.  The design is printed on a white band near the top of the glass, and might be from Libbey.
