'Charisma is more than just the last great Specialty Line the Blenko Glass Company produced; it is an uncommonly beautiful and eloquent swan song for the company's Historic Period of 1947-74 courtesy of John Nickerson in his first full year as the company's design director.
As discussed on the Blenko Museum's website "A Specialty Line is a themed group of designs that are technically 'special' or different from the company's normal production, and consist of multiple shapes that are aesthetically related. [the] Specialty Lines were an important departure for the designers and indicate an impulse to innovate and experiment in spite of the risks. The Specialty Lines are a testament to a company in its prime."
To borrow from my explanation of Charisma published in the 2007 issue of Miller's Guide, the Charisma line consist of 10 designs executed in crystal with an internal garland pattern Ruby colorway. The technique was an appropriate and historically relevant one as it was essentially a revival of a technique used in the mid-Atlantic region of America circa 1860-1880. Mid-Atlantic glass is recognized as an important milestone as it was the first large scale iteration of the American glass industry, established in 1739.
Charisma was a significant, if short-lived, move towards more technically demanding and elaborate work at Blenko. It represented their first instance of the use of an internal colorway as well as the revival of the concept of the Specialty Line which was formally established in 1960 by Wayne Husted ( Rialto , Regal and Raindrop ). This revival is surprising in that the 1960 experiment was a financial disaster for Blenko and can perhaps be interpreted as a last resort; Charisma was effectively a line in the sand against the encroaching competition of Studio Glass . Sadly this line was ultimately crossed against Blenko's favor.'
