| Breaded Pigeon Sketch by Estelle Rocca-Serra |
The kneaded soft white of the bread can be used as an eraser, its light stickiness will gently pick up particles of charcoal, graphite and even dust on drawings. It is gentle enough not to roughen the surface of soft and delicate paper.
Even more surprisingly, it is well known to be used for art conservation, in particular it is one of the safest ways to clean watercolour and gouache paintings, but less well known is its use to clean varnish tempera and oil paintings.
Our friend the pigeon holds quite a strong stance against this specific use of his staple food, but to be perfectly honest his position would be more credible if he wasn't already covered in crumbs and he is not really our friend anyway! Go have a wash mate!
