Figure 3 Ink bottle, Doulton, Burslem, Staffordshire, ca. 1899. Stoneware. H. 8". Doulton ink wells and bottles are a collecting field on their own. This example of a Stephens sheered-neck bottle has wider interest, serving as a reminder that diamond-shaped registry marks were applied to ceramics of all kinds across more years than the marks state. This example was registered in 1876, but the inclusion of the word LIMITED in the Doulton factory mark puts the bottle no earlier than 1899.
