At the heart of this exhibition are three new such series: a line of five pastels, treated like a kind of reverse sculpture, with fat sticks of chalky pigment ground
back to dust and worked into thick pages of handmade paper; a sequence of 18 watercolours in which pairs of pigments are dissolved into each other, layer over layer, into veils of translucent light; and a series of ten tall, vertical
sheets of
waxed butcher's paper, carrying oil paint dissolved into skins of solid and liquid colour.
