Broadstairs Pottery was founded by David White in 1968 as a successor to an earlier firm Thanet Pottery. For the mark, see ‘British Studio Potters’ Marks’ by Eric Yates-Owen and Robert Fournier (2nd edition 2005 p534). White worked there with assistants, some of whose initials appear on the pieces produced, until 1983 when he closed to business to concentrate on his own work, an example of which can be seen elsewhere in this sale. Both the incised geometric bands and the pronounced ridging effects are hallmarks of the firm’s output and this bowl and cover, marked only with the factory name, is a classic example of its productions.
