[3][4] After graduating, she worked as a freelance painter and made designs for ceramics, decorations for cut glass, jewellery and ivory paintings, selling her pieces through the Wiener Werkstätte.
[14] In 1925 she was invited to present vases with black enamel decoration[15][16][17] and the showpiece "Die Welle Woge" (The Billowing Wave), which was to form the focal point of the glass section of the 1925 exhibition, at the Exposition Internationale des arts décoratifs et industriels Modernes in Paris.
Alongside Hertha Bucher[19][20] Mathilde Jaksch,[21] Ida Schwetz-Lehmann and Dina Kuhn,[5][10] Ena Rottenberg established herself as one of the most influential designers at the manufactory.
The exotic-looking design of the Orient service with various lid knobs in the form of "exotic heads", figures from countries where tea and coffee is grown, was particularly successful.
Schlevogt had commissioned pieces from sculptors including Ena Rottenberg and Josef Bernhard, which are credited as part of the reason that the pavilion won the award.
