Is there something about glass you’d like to know? Ask a Librarian!

Have you ever wondered what raw materials are combined to make a batch of glass? Are you looking for information on a certain glass artist? Is glass a liquid or a solid? Do you know where to look to try to figure out what company made that glass piece that was passed down to you from your great grandmother? These are all examples of the types of questions that the Rakow Research Librarians answer quite frequently. There are currently over 700 question and answer pairs viewable online and that number is constantly increasing as over 4,000 reference questions are asked each year. Ask us your questions through our customized online reference service, LibAnswers.

Gemmaux in the Collection of The Corning Museum of Glass

Earlier this year, Tina Oldknow, the Museum’s curator of modern glass, asked me to research 16 glass panels affixed to light boxes in the Museum’s permanent collection.   The panels, made in the 1950s and 1960s, came to the museum in 1993, and are called gemmaux.  I had no idea what gemmaux were when I began my research, but I was excited for the challenge.  I began my search by looking through the curatorial files on the objects in our collection.  I also was able to find information online through the Archives of American Art at the Smithsonian Institution and through the Rakow Research Library here at the Museum.

Gemmail (plural gemmaux) is a French word that is literally translated as “enamel gem.”  The term was coined by French painter Jean Crotti to describe a technique he developed for layering and adhering pieces of colored glass onto a panel in order to create compositions that are meant to be viewed in front of a light box or illuminated from behind.  Gemmaux were very popular in the late 1950s and 1960s. They were made by technicians called gemmistes at a Paris studio called Les Gemmaux de France.

Gemmistes used existing artwork by well-known artists, like Pablo Picasso and George Braque, to create re-interpretations of their work using the gemmail technique.  Sometimes these artists even came to the studio to sign the gemmaux when they were finished.  Young French painters also experimented with the technique.

Fifteen of the 16 gemmaux panels in the Museum’s collection were given by Pittsburgh Plate Glass Company as a gift in 1993.  These 15 panels were part of a 1962 traveling exhibition called Masterpieces in Glass organized by Pittsburgh Plate Glass Company to promote their fiberglass curtains.  The Rakow Research Library has two full-color 1961 advertisements for the Masterpieces in Glass exhibition that showcase the gemmaux alongside fiberglass curtains.  Each panel depicted is now in the Museum’s permanent collection.

(93.3.15, gift of Pittsburgh Plate Glass Co.) (Rakow Library bibliographic record number 131016)

Since I began my research, there has been a surge of public interest in this unusual mid-20th-century technique and the information I was able to uncover on the history of gemmaux has grown larger than a blog post can contain.  So I wrote an article called A Brief History of Gemmaux. It is a fascinating history!  You can also view all of the Museum’s gemmaux panels by using the online collections browser.

Introduction to the Collection Series: Exhibition Catalogs, Price Guides, and Batch Books! Oh, my!

At the core of The Rakow Research Library is the book collection, numbering approximately 37,500 titles. We try to obtain every book on the history and art of glass and glassmaking, meaning new, old, and rare volumes are constantly being added to the collection. The acquisitions team is responsible for purchasing books and receives suggestions from reference librarians, curators, and other museum staff. There are three primary ways in which books are acquired. They can be purchased from a vendor, they can be received as an exchange from other libraries, museums or universities, or they can come in as donations. With “glassy” books, we try to obtain one copy for public use and a second non-circulating copy.

Recent acquisitions in the Rakow Library

Recent acquisitions are put out to view.

Along with the obvious glassy subjects such as glassmaking techniques, stained glass, glass artists, and glass company histories; topics range from architecture to Christmas ornaments to neon and beads. Fiction, children’s books, craft instruction and pattern books, glass dictionaries, and identification and price guides are here, too. We have unique materials that are self-published by contemporary artists. In addition to those, we also collect in subject areas that support glass research, including archaeology, ceramics, and other decorative arts, to name a few. Materials in our collection can be found in more than 50 different languages. The oldest book dating back to approximately 1150 is the Mappae Clavicula, which was hand-copied by monks and contains formulae for making colored glass.

Kelly Bliss is in charge of cataloging the book collection. Nearly 50% of the book cataloging that Kelly does is original, meaning that no other library reports holding that item. Kelly’s favorite book in the Library is a William Leighton Batch book, which was donated by the family in 1993. A batch book is a glassmaker’s recipe book for different types and colors of glass. Dated October 1850, this miniature book inside a leather case was written by hand and contains 46 pages of recipes that easily fit in the palm of your hand. Additional miniature pages contain typed up recipes. Like many other items in our collection, it is one-of-a-kind.

Though we used to microfilm rare books for preservation and circulation, they are now being digitized for increased accessibility. Some books have been put on “page turning” software and are available on our website allowing patrons to read the digitized versions. We are happy to lend any books through Interlibrary Loan provided that we hold at least two copies, and we encourage you to visit and see the collection first hand. Kelly says, “People can’t imagine what we have . . . to look at all of the different topics we have, they would be amazed.”

Introduction to the Collection Series: The Rakow Research Library Article Index

Article Index is one of the Rakow Research Library’s two main holding catalogs. It is locally created, maintained, and edited by the bibliographer and other staff members of the library. It contains citations to articles in journals, magazines, newsletters, and other periodicals owned by the library. Article Index also contains citations to book chapters, known as analytic entries. The Rakow Research Library’s periodical collection covers a wide range of topics and time periods, the common thread being the presence of glass content. Consequently, a typical stack of periodicals that ends up on the bibliographer’s cart would likely contain a selection from the following:

  • Journals and magazines with sole focus on glass (Glass Art, Glass Club Bulletin, Glashaus, etc.)
  • Archaeology journals covering all time periods and geographic locations (Medieval Archaeology, Slovenská Archelógia, Journal of Roman Archaeology, etc.)
  • Newsletters, bulletins, annual reports, acquisitions, and catalogs of museums, collectors’, or historical societies (La Revue des Musées de France, NewsJournal of the Early American Pattern Glass Society, Annual Bulletin of the Paperweight Collectors Association Inc., etc.)
  • Publications focusing on one type of glass, such as historical stained glass, beads, bottles, paperweights, marbles, etc. (Stained Glass, Glass Bead, Bottles and Extras, etc.)
  • Journals and magazines focusing on one geographic area or culture (Arts of Asia, American Indian Art Magazine, African Arts, etc.)
  • Journals, magazines, and newspapers covering the antiques and collectibles field (Antiques and the Arts Weekly, Antique Collecting, The Magazine Antiques, etc.)
  • Journals and magazines covering the arts (fine, decorative, and applied), art history, crafts, design, and interior decoration (Form Function Finland, Design Matters, Deutsche Kunst und Dekoration, etc.)
  • Journals and magazines with focus on contemporary architecture, interior design, and lighting (L’Architecture d’Aujourd’hui, Domus, Metropolis, etc.)
  • Journals and other publications covering the fields of glass science, technology, conservation, and industry (Glass Technology, Rivista della Stazione Sperimentale del Vetro, Glass International, etc.)

While the Rakow Research Library theoretically collects materials in all languages, those most commonly occurring in the library’s approximately 850 current periodical subscriptions are: English, French, German, Italian, Czech, Spanish, Russian, Dutch, Polish, Swedish, Hungarian, Danish, Romanian, Serbo-Croatian, Slovak, Ukrainian, Portuguese, Hebrew, Arabic, Turkish, Mandarin, Japanese, Korean, and Greek.

In addition, articles can also be found in the so-called Vertical Files (VF), located in steel cabinets along the wall of the stacks area. This resource typically contains offprints of book chapters and photocopies of articles from older issues of newspapers and magazines. Article Index holdings can be searched online at http://www.cmog.org/research/library/catalogs.

Remembering Axel von Saldern

Axel von Saldern

Axel von Saldern

(1923–2012)

Axel von Saldern, one of the founding staff of The Corning Museum of Glass, a prominent glass scholar and an active Corning Museum Fellow, passed away June 2, 2012. His influence on The Corning Museum of Glass and the world of glass is long-lasting.

“His liberal but firm attitude and his comments made him a natural authority, not only in his main field of study, the history of glass, but also in the fine and decorative arts, the museum world, his broader family, and far beyond.” says Dedo von Kerssenbrock-Krosick, the Museum’s former curator of European glass and now head of the Glasmuseum Hentrich, Museum Kunstpalast, in Dusseldorf.

Von Saldern, who was born in Potsdam on July 28, 1923, began his employment at the Corning Museum as a cataloguer on January 2, 1954. Glass was a completely new subject to Axel when he arrived in Corning. The Museum was then housed in a tiny portion of the space that it occupies today, and both the staff and the collection were small. But it was a growing institution, and it quickly began to be recognized internationally, not least among archaeologists.

Corning allowed for pioneering research and prominent acquisitions, and Axel made ample use of both. One of his first activities at the Museum seems to have been assisting with the organization of the exhibition The Story of American Pressed Glass of the Lacy Period, 1825–1850 (1954). In 1956, Axel traveled to Cologne with the backing of a considerable budget for the acquisition of glass at the Lempertz auction house. Because of his interest in ancient glass, he was assigned to be the Museum’s contact person for the collector Ray Winfield Smith, and he eventually chose a significant part of Smith’s holdings to be added to the Corning collection.

Ancient glass from the Ray Winfield Smith collection

Axel started to travel to the Near East in 1967, and he studied and published the glass finds from Gordion and Sardis. He also helped to found the Journal of Glass Studies, which he co-edited, and he contributed an extensive paper on Gordion to the initial volume of that publication in 1959. Cut glass of the Achaemenian, Sasanian, and Islamic periods became his core specialty. But the Corning Museum’s collecting activities encompassed the entire field of glass art, and so did Axel’s studies. His most prominent accomplishment for Corning was his formidable book on German enameled glass, which, as a survey of this subject, remains unsurpassed.

Following a position at the Brooklyn Museum of Art from 1961 to 1966, he returned to Germany, where he assumed the positions of curator of sculpture and decorative arts and vice director at the Kunstmuseum (today, the Museum Kunstpalast) in Düsseldorf where, under Axel’s curatorship, glass became an independent department of the museum.

In 1971, von Saldern was appointed director of the Museum für Kunst und Gewerbe in Hamburg. There were 17 exhibitions in 1973 alone, and von Saldern’s major shows—including Tutankhamen (1981), the Bugattis (1983), gold and silver from the Kremlin (1986), and Lalique (1988)—are among the most ambitious and successful that the museum has ever presented.

In 1988, von Saldern retired, and soon thereafter he and his wife Maria relocated to Starnberg, near Munich. One year before his retirement, he had become president of the Association Internationale pour l’Histoire du Verre (AIHV), and he had served for decades as head of Section V of the German Society for Glass Technology.

Says von Kerssenbrock-Krosigk, “It was only after his retirement that von Saldern found time to complete his magnum opus, an outstanding and far too little known book on ancient glass.This massive volume of 708 pages contains 64 plates, about 1,500 footnotes, and everything that von Saldern knew about glass from early Mesopotamia to the fall of the Roman Empire. Following Anton Kisa’s Das Glas im Altertume (Leipzig: Verlag von Karl W. Hiersemann, 1908) and Donald B. Harden’s “Ancient Glass” (published in The Archaeological Journal in 1969, 1970, and 1972), this was the third attempt to summarize the entire knowledge of ancient glass in one volume.”

Following the publication of his final book, von Saldern gradually retired from research and art history. But he remained incredibly alert, informed, and open-minded until the very last minute of his life. He died, suddenly and unexpectedly, in his garden in Starnberg, on June 2, 2012—but not before he had confirmed his place in the pantheon of the most eminent scholars of the history of glass.

Introduction to the Collection Series: Trade Catalogs for Glass Research at The Rakow Research Library

The Rakow Library is home to an extensive collection of glass company trade catalogs. Approximately 17,000 trade catalogs in various languages, representing firms worldwide, are housed in our temperature and humidity controlled secure stacks with preservation in mind.

A trade catalog is issued by a manufacturer, distributor, wholesales, or retailer with the intention of promoting business. Trade catalogs are invaluable resources for identifying manufacturer’s styles, patterns, dates of production, and original prices. They also provide background on economical and social circumstances for the times in which they were published.

Trade catalogs are primarily used for identification purposes by an audience of collectors, researchers, curators, and members of the public wanting to identify glass objects. For ease of access, we have categorized trade catalogs into the following subject areas: bottles and druggists’ glassware, cut glass, flat glass (including stained and architectural), laboratory ware (including industrial and optical), lighting glassware and lamps, tableware, tools (glass blowing and working tools), glass art, paperweights, and glass jewelry, among others.

The Rakow Library is committed to acquiring and preserving these materials and pursues expansion of the collection. Sheila Tshudy, in charge of trade catalogs, contacts firms, works with rare and second hand book dealers, and searches eBay to find new additions. The ever-growing collection is also supplemented by gifts from generous donors.

Though our trade catalogs do not circulate, they are all available for use in the Library and we do loan microform copies, if available, through Interlibrary Loan. A large part of this collection was microfilmed and we have over 1,000 microform catalogs which were filmed with permission while on loan to us from other institutions and private individuals. The earliest dated catalog is a price list from 1722, from the firm Manufacture Royale des Glaces de France (Saint-Gobain) entitled Tarif du prix de glaces de la Manufacture royale.

Digitization of select trade catalogs from the collection allows us to provide access to these unique resources via our website. The digital collection is continually growing, and currently more than 200 trade catalogs are available digitally to be viewed in their entirety. We encourage you to visit The Rakow Research Library and consult these valuable resources.

The Museum’s newest teen program: Junior Scientists

Ever wanted to learn more about the science of glass? Here at the Museum, a group of area students are doing just that in the Junior Scientists program, new this year.

Junior Scientists learning about the properties of glass

The small group of students from local Corning middle and high schools are in grades 7 through 9. The program began in March, and is wrapping up on June 12. Through hands-on experiments and behind the scenes tours of the Museum and Corning Inc. labs, the students are learning about science through the process and properties of glass.

Seventh-grader Pearl describes why she wanted to become a Junior Scientist:

Pearl making a Prince Rupert's drop

As a visitor to The Corning Museum of Glass, I have been amazed by the glass artwork. When I was younger, I always thought glass was super fragile since I broke glass dishes often. Now I know that this isn’t always true, and that it can be very strong. For example, fiber optics are super thin glass that can bend without snapping. I think this is outstanding and proves my old belief, that glass is nothing but an easy-to-break decoration, wrong. There are many different types of glass and they are used for different things. To illustrate, glass is found in everyday objects such as tables, windows, cell phones, and jars. Not only is glass pretty, but it is useful.



Students in the program are learning all about glass and what it can do by investigating the material through experiments and research. The focus of their research this year is stress and tension in glass. In their weekly after-school meetings, the Junior Scientists have toured the Innovations Center at the Museum, watched a special glass breaking demonstration, and gathered information for their research at the Rakow Library.

In an experiment that quickly became a favorite experience for many of the students, the group had a hands-on workshop at The Studio where they made – and more importantly, destroyed – their own Prince Rupert drops.

Each Junior Scientist was tasked with designing, creating, and carrying out their own experiment over the course of the program. To assist in their research, the students met and worked with scientists from Corning’s Sullivan Park on the concepts for their experiments. The Junior Scientists will present their findings at a finale event on June 12.
