Marqueterie sugar bowl. 

This distinctive Lambeth ware was produced between 1886-1906, although examples are unusual due to its fragile nature. Multi-coloured clay in blue, white and brown were compressed together resulting in a marble effect clay, which would then be moulded into often intricate shapes. This particular ware bears a Doulton & Rix mark to its base,William Rix was art director at Lambeth between 1870-1897.
