Two lovely green glazed mugs from the Grahamstown Hamburgers Pottery. There is not a lot of information on this pottery. If you would like to perhaps start a collection of this potters work or find out about his work, I suggest “scorched” Earth by Wendy Gers, a fantastic reference book on southern African potteries. The mugs are not identical at all and the glazes are a little different. There are bubbles in the glaze at the base of one mug. See Pix. The are a bit greener than the pix show. Don’t hesitate to ask any questions. Tks.
