  This would be rather an unusual use for cellosolve.
  The usual solvent for celloidin is a 50/50 mixture
  of ether and absolute alcohol. You can use anaesthetic-grade
  ether, which contains stabilizers to delay the formation
  of peroxides. It is, of course, still highly flammable.

  It is often convenient to stain big celloidin sections
  unmounted, without removing the embedding medium. (It doesn't
  stop the stain diffusing, though it can become stained
  itself.) The best place to find detailed instructions is
  an older textbook (if you don't have an older colleague,
  which is better). There are various ways to go about staining
  and mounting these sections.
