An article in the American Bee Journal, Oct. 1998 issue, pp 741-742, by M.
Del Hoyo, M. Basualdo, and E. Bedascarrasbure, describes tests performed on
the efficacy of hot paraffin for killing AFB spores.  Some spores survived
temperatures as high as 135C (275F), but none survived 160C (320F).  If this
is true, it is doubtful that melted beeswax, or exposure to 60C degrees,
kill AFB spores.
