By putting an ounce of alum or sal ammoniac in the last water in
which muslins or cottons are rinsed, or a similar quantity in the
starch in which they are stiffened, they will be rendered almost
uninflammable; or, at least, will with difficulty take the fire, and
if they do, will burn without flame. It is astonishing that this
simple precaution is so rarely adopted. Remember this and save the
lives of your children.
