Blenko Design Numbers

Blenko has always identified each design it produced with a unique number. To authenticate an item as Blenko one must be able to match the shape to a corresponding design number shown in a catalog. Following is an explanation of the three different numbering systems The Blenko Glass Company used.

About "Experimental" Items With No Design Number:
Beware! Each year Blenko produced new designs to add to the line, a small number of items, about 5 at most, were rejected each year for a variety of reasons (cost, difficulty to produce, marketability, aesthetic shortcomings, etc). Commonly two prototypes, only occasionally more, were made of these rejected designs and then sold in the Visitors' Center (or its precursor). Noteably many of these items were made by using old molds for the initial form and so bear a resemblance to other designs. "Exprimental" items are best avoided unless accompanied by convincing documentation as their authenticity and relevance will otherwise always be highly questionable at best.

Most items people call "experimental" Blenko (aka 'one-offs', 'end of day', 'whimsies', 'lunch hour specials' etc) are almost always another company's product that the owner can not identify; the famous example is on p.83 of Schiffer's book "Blenko Cool", first ed., which identifies a Zeller vase as "experimental Husted." Similarly, p.40 of the second edition inexplicably identifies the quite common 5831 from Blenko's standard line as "experimental."

Numbering System Prior to 1948
There is currently no evidence published to conclusively indicate how design numbers were assigned in this period, though similar designs or variations often appear in series.

The numbering system does not correlate to the post-1953 system in terms of the first two numbers indicating year - at the very least if that system was used it was not used exclusively or consistently. As such one can not infer that, for example design #3724 was designed in 1937. It is however, reasonable to assume, but by no means assured, that pre-1948 design numbers may roughly indicate chronological order as they may have been applied sequentially.

In some instances the pre-1948 system conflicts with the post 1953 system. For example #517 was designed circa 1940's. However, such conflicts are rare.

Numbering System 1948 to 1953
During Winslow Anderson's tenure, design numbers are primarily designated with the "900" series (from #900 to #999). While the "900" series constitutes the majority of Anderson's designs, he did produce more than 150 new designs, including such items as the #497 bar set series, the #19 series of florifom plates, and almost all "53" series designs.

Interestingly, Anderson did not claim either the "600" or "800" series as his and they do appear to predate his tenure in the catalogs, this corroborates Anderson's claim that he was not responsible for devising the "900" series system and that method was in use prior to his tenure.

Numbering System 1953 to 1974
In 1953 Blenko adopted a system that stayed in place until 2002: design numbers are either 3 or 4 digits in length. The first two digits indicate the year the design was introduced (ex: 5310 was designed in 1953). The one or two digits after the first two have no significance other than to serially distinguish designs. It is important to note that it is not true, for instance that #552 was necessarily designed after #551; rather, they were simply assigned numbers in that order and the designation was usually not made by the designer.

Letters On Design Numbers
Letters following design numbers most commonly indicate size; X, S, M, L, LL (extra small, small, medium, large, extra large).

Other uses of letters include:
- in early items, letters indicate ornamentation or style, ex: "L" at the end can indicate that "leaf" decorations are added to a shape, "B" at the beginning indicates controlled bubble
- on barware letters designate function, ex: CT= cocktail, HB = highball
- distinguish versions of designs in a series as in 65A, 65B, 65C, 65D

Official Blenko Catalog Issued Design Names

The only universal and official way to identify a Blenko design is by its number. However, some descriptive or allegorical names were printed in the catalogs alongside the design numbers. After and including the year 1960, Blenko catalogs contained no names or descriptive terms, identifying items exclusively by their design number and dimensions; therefore no post-1959 design has an official name. Below are 12 of the most memorable official Blenko design names.

Common Use Names for Blenko Designs

Common use names are those that are given by collectors. We are of the opinion that if a design already has a serviceable official catalogue name it is inappropriate to re-name it. Evocative, poetic or allusive names are the sole prerogative of the designer (ex: Napoleon decanter, Gurgle decanter), others are best left to applying brief and accurately descriptive terms as names that effectively recall the design rather than inventing interpretive ones.
