Sulphur Bleach
Dear Aunt Vaisy, About mulberry stains, you need have no fear of blue or pink muslin being decolourised, or, if it is, you can be sure that on exposure to sun and air it will gradually resume its original colour. The reason for this is that when sulphur is burnt in air, sulphur dioxide is formed. It is the sulphur dioxide that may bleach wet material, but the bleaching action is not permanent and the material will, as I have said. gradually resume its nor-
mal colour.
