Here's a wonderful Marie Kirschner designed Loetz vase, Candia Silberiris finish, light green with a mixture of light blue finish.

Marie produced 277 unique patterns for her own personal sales.  Marie funded these designs, by in return designing glass for the Loetz factory's normal production, and some of the glass pieces from her own series were also adopted by the factory for its normal production range.  These pieces do not carry the artist's signature as the Loetz factory didn't have the rights to use her MK monogram.

Her designs were mainly influenced by ancient ceramics, Eastern Asian forms and Central European utilitarian shapes.  Her goal was to achieve the greatest possible aesthetic unity between the glass vase and the flowers intended for it. 

Typical features of her glassware are the simple geometric and stereometric forms, such as triangles, ellipses, circles, spheres, pyramids, rectangles, rhombuses, squares, and cylinders used in various designs.

To help make the vessel profiles less severe, she used a great variety of bizarrely shaped handles for many of her designs, giving some of the vessels a functionalist appearance.
