This is the painting “Green and White” by Sandra Blow, created in 1969. It’s a square canvas, roughly 3 metre on each side, worked with acrylic paint, ash and charcoal. What’s really fascinating is the story behind the surface. Blow mixed ash she’d made from burning nuts in her studio stove and layered it over the paint. Half‑finished, a visitor slipped in and cut the canvas with a knife—an accidental vandalism. Rather than abandon the piece, she sewed the edges together, glued strips of canvas to the front and back, and then painted over the repair. She says, “Miraculously… it was a perfect conclusion to the whole painting.”
Blow was known for using both conventional and unconventional materials to push abstraction forward. In this work you can see the geometric, non‑representational language she favoured, yet the green‑white colour scheme hints at a soft landscape. The painting was presented to the collection in 1994 by the Trustees of the Chantrey Bequest. It now hangs in the Modern and Contemporary British Art room of Tate Britain.
