    Cross processing... BW slides?

    How do I take negative BW film and develop it as a positive BW slide?

    You develop it as normal, rinse/wash, then bleach it, then rinse, then pull it ou and hang it up to dry in light, then get it back onto the reel, develop again (no times for this, process to completion, ie you cant overdo it, just underdo it) and fix.

    So I develop as normal, NO FIXER, THEN bleach & rinse with clorox, hang to dry, Re-spool, bleach until something happens in clorox, develop again in daylight until it looks good, and fix?

    Not exactly, you don't use clorox, you don't hang to dry, but reexpose etc...
    The whole process can be found here.
    Btw, it's not the only method.

    Are there any alternatives I can use for the bleach besides potassium permagnate and H2SO4? What about Lysol and stop bath?

    The pure Lysol completely strips all emulsion off the film, developed or not.

    I have often wondered if E-6 Reversal Bath will chemically fog a piece of b/w film, instead of pulling it out in the light. I have also wondered if plain-ol' pot. ferricyanide bleach would do the job of the Ilford bleach recipe.

    The separate E6 reversal bath should work fine after all all colour films are essentially B&W until developed in a colour developer.

    The Ferricyanide bleach won't work as the Silver/Ferricyanide complexes formed are partially insoluble so don't wash out and the negative would partly re-develop along with the positive.

    You should be able to use a colour bleach on it.

    Hanging it to dry is easier, as you dont have to hold the reel and worry about re-exposing it to light for the correct time and making sure all the film gets enough.
