Concentric rings set in a ground of veined cream coloured glass over clear glass - difficult to capture in images. Graduated green band at the rim. The bowl is 39 cm in diameter and 9 cm in height.
 
WMF started making glass in 1883 when a glass house was built at Geisslingen near Stuttgart to produce their own glass inserts. The original 1883 glass house was destroyed during the First World War and a new, more modern facility opened in 1922. The young glass designer Karl Wiedmann perfected the technique of iridized surfaces and the resulting "MYRA"- Kristall entered production in 1926. The same year also saw the beginning of the first "IKORA" glass - reputedly discovered by accident whilst correcting a Myra glass piece. Both Myra and Ikora glass continued to be produced until around 1936, when production of art-glass ceased. Because of the technique used, combining colours and treatments, each Ikora piece is unique.
