There is a lot of information about glass canes, including "whimsies" that were made by glassblowers. This book by Catherine Dike is one place to start:
Dike, Catherine. Canes in the United States : illustrated mementoes of American history, 1607-1953 . Ladue, Mo. : Cane Curiosa Press, 1994. 397,  p. Glass: p. 230-233.
This article also tells the story:
Sutton-Smith, Barbara. “The Glass Cane: A Symbol of the Artisan's Skill.” Antique & Collectibles Showcase, v. 41, no. 3, Jan./Feb. 2006, pp. 40-41, ill. Mainly 17th to 19th centuries.
I have attached a list of additional books and articles about glass canes. If you wish to obtain copies of any of the items on our list, please contact your local library.
