The twintone colour combinations are around since 1936. Some combinations were commercially more successful than others (Sepia and Mushroom for example) and were used for decades. Others such as Mushroom and Peachbloom lasted only a year due to their unpopularity.
1940's glazes: C50 Pink and Seagull, C54 Sepia and Mushroom C57 Ice Green and Seagull C65 Magnolia and Shagreen C85 Sky and Magnolia
These pieces have usually white glaze inside and white lids. The glaze is shinier than the Twintone glazes.
The Blue Moon glaze was also the basis for the Lucullus range (using the new transfer print method), launched in 1962 and designed by Robert Jefferson. Another design was the 'Herb Garden', launched in 1963 and based on a sunshine yellow glaze. The contour shape, designed by Jefferson was also used for the 'Desert Song' design. This was designed by Pat Summers.
