The sea has endless nuances of blue, a bright turquoise, Caribbean and warm. But it can also be icy, dark, almost black. As the sky dips into the mirror of the oceans, the unfired porcelain absorbs the cobalt blue of the painter's fine brush. Deeply and without the possibility of correction, what has belonged together for thousands of years - cobalt is the coloured soul under the glaze. The painter must master his craft; a mistake with a line and the work is lost.
