What does it mean to "wax hot"? [closed]

meaning

Reading "Psychology, Briefer Course" by William James I stumbled upon the following¹:

How easily do we forget a bodily discomfort when conversation waxes hot

By context, I'd suppose it's something good; but what exactly does it mean to say that a conversation waxes hot? I tried my best but could not relate to anything I know of either wax or hot (I'm not a native speaker).
