    However, the white residue on the fitting may be from asbestos that was removed in the past.

    The only way to know is to have it tested.

    My Guess is fiberglass and possibly asbestos under.

    How old is it? Is it hard or soft? Hard to say positively from the photo but I am 95% certain it's glass, due to the 1/2" of visible medium at the end. The elbow however, may be asbestos (or plaster) but it appears you've already disturbed whatever it is. Get it tested if you're unsure. At the very least, wet it down and bag it before you do any cutting to keep the particles from becoming airborne
