        Black polyethylene??  Hell no!  Not for all the tea in
        China (or all the polyethylene in Dow Chemical Co.).

        The blackness is due to =carbon= black.  God save your
        immortal soul (and mortal capacitors) if you use such
        a dielectric.

        The clear polyethylene is the dearer because it's
        comparatively virgin (like my sister on her wedding day,
        but that's another story).  The black poly is invariably
        recycled (from whatever) -- the blackness hides a multitude
        of its sins (like adultery in the moonlight).

                                       Yours for seeing clearly,
