hese two highly decorative pieces are extremely rare and interesting examples of Algerian Kabyle pottery and previously formed part of the 'Great House Collection' in Kegworth Derbyshire and were most likely purchased and brought back from a Grand Tour type trip in the 19th century.  I have noted whilst researching, two other simarlarly decorated items can be found in the Victoria and Albert museum, London.  See link (https://collections.vam.ac.uk/item/O163952/vessel-unknown/).
 
The construction and design of the pair shown are typical to the Kabyles people. The clay was shaped by hand using the thumb and coiling methods. Before firing, the vessel was decorated with kaolin, coloured oxides and slips (liquid clay), usually in blocks of red and white overlaid by geometric designs applied in black. Pots not intended for use in cooking, like this one, also had a resin applied to give a glazed surface. This gave a yellow colour and ensured that the pot was watertight.
