Each heating plate 107, 108 comprises a glass substrate and a transparent thin film heating element 1500; 1501. Said thin film heating element 1500, 1501 has a film thickness which is relatively greater towards a lower region 1502, 1503 of said plate compared to a thickness of said heating element at an upper region 1504, 1505 of said plate. The film thickness may vary in a straight line linear manner between said lower region and said upper region or may vary as a series of discrete steps.</p> |
