QUESTION: I like to collect art glass. Over the years, I added many pieces to my collection. Recently, I discovered a beautiful vase at an antique show. The dealer said it was made by Loetz of Czechoslovakia. From its design and form—it’s a classic green vase with large orange dots—it looks to be Art Nouveau, but I’m really not sure when the company produced it. What can you tell me about Loetz Glass? I’d like to add more pieces to my collection. Did they only make one type of art glass or did they diversify?
ANSWER: Loetz produced your vase around 1911, so it definitely falls within the time of Art Nouveau. Loetz was the premier Bohemian art glass manufacturer during the Art Nouveau period from about 1890 to 1920.
It’s commonly believed that Johann Loetz founded his glassworks in 1840. In fact, Johann Eisner, another glassmaker, opened a glassworks four years earlier in Klostermühle, a town in southern Bohemia, in what’s now the Czech Republic. His heirs sold the glassworks to Martin Schmid in 1849, and two years later Schmid sold it to Frank Gerstner, attorney-at-law, and his wife Susanne, who was the widow (Witwe in German) of glassmaker Johann Loetz.
Gerstner transferred sole ownership to his wife shortly before his death in 1855, after which she successfully expanded the company for 20 years, manufacturing mainly crystal, overlay and painted glass.
In 1879, Susanne transferred the company, now called Johann Loetz Witwe, to Maximilian von Spaun, the son of her daughter Karoline. One year later, von Spaun hired Eduard Prochaska and the two of them modernized the factory and introduced new, patented techniques and processes.
Before Loetz became known for its Phänomen and "oil spot" pieces, it had pioneered a surface technique called Marmoriertes, which produced a marbled red, pink, or green surface on objects such as vases and bowls which imitated semi-precious stones, such as malachite, onyx, and red chalcedony.
Phänomen featured rippled or featherlike designs on the object’s surface. Loetz artisans achieved this unique effect by wrapping hot glass threads around an equally hot molten base. They then pulled threads on the piece’s surface to make waves and other designs while the materials were still malleable. They combined this with techniques pioneered by Louis Comfort Tiffany in the United States.
Another late-1880s forerunner of its most prized pieces was its Octopus line, whose white curlicue lines on a darker, mottled surface resembled the tentacles of octopi.
In 1889, the company took first prize at the Paris Exhibition for its classic vase forms, some of which were hand-worked and deformed into swirling, organic-looking shapes like seashells, flowers, and tree trunks. Decorative vases, cups, and pitchers were other popular forms in the Loetz lineup, and many of the pieces glowed thanks to their iridescent sheen from the firing and reduction techniques.
By 1904 sales began to fall off as the interest in Phänomen glass had begun to decline. So the company intensified its collaboration with Viennese designers to compensate for a lack of its own innovation. In 1909, Loetz appointed Adolf Beckert, a specialist in etched decoration, as its new artistic director. In the same year, von Spaun transferred management of the glassworks to his son, Maximilian Robert. But financial problems forced the company into bankruptcy in 1911.
Another series from the turn-of-the-century was known as Streifen und Flecken, or stripes and spots, whose cheerful shapes and colors were as friendly as a polka-dot skirt from the 1950s. Asträa pieces also had oil spots, although the base color tended toward the metallic. Works in the Diaspora series were almost all dots, whether it was a simple vase or a one shaped like a chambered nautilus.
The use of patterns was also a hallmark of Loetz art glass. The Spiraloptisch were a blizzard of spirals, while the more formal looking pieces in the Décor series were painted and etched with leaf and flower shapes to create works with an almost Asian sensibility.
After 1905, when interest in the florals waned, Loetz artisans pushed their glass surface treatments further than ever while relying on shapes that the company had used for decades. For example, the roiling surfaces of the Titania pieces pre-date Abstract Expressionism by 30 years. Loetz’s Perlglas pieces were translucent, giving more weight to the forms as sculpture rather than distracting the viewer with dazzling surfaces.
But without a doubt, the most memorable Loetz art glass from the end of the Art Nouveau era was its Tango line. Unlike the work that had preceded it, which was all about dense color combinations and tricky surface treatments, these two-toned pieces typically featured single colors on mostly unadorned surfaces, with contrasting lip wraps or handles.
The last significant period for Loetz occurred between the wars. In the beginning of the 1920s, Loetz revived late 19th-century cameo glass, which had been pioneered by Émile Gallé and others. Compared to the work that had come before it, these Loetz vases, bowls and jugs, with their etched, almost sentimental depictions of flowers and scenics, were traditional and safe.
But by 1939, the company had begun to run out of money, and in 1940 a disastrous fire destroyed the factory. After the war, the East German Government nationalized Loetz Witwe, but in 1947 the lights went out for good.
