> cigarette lighter held next to petrified wood (to use an atomic bomb era analogy)

Can you, or anyone, explain the lore here? I get it's impossible to light it on fire, but what's the context? I tried searching for the expression and couldn't find anything.

George Gamow found a way to dramatize how unpromising Teller’s Super had proven to be. John McPhee reports the story as Los Alamos physicist Theodore Taylor remembered it. “One day, at a meeting of people who were working on the problem of the fusion bomb . . . Gamow placed a ball of cotton next to a piece of wood. He soaked the cotton with lighter fuel. He struck a match and ignited the cotton. It flashed and burned, a little fireball. The flame failed completely to ignite the wood, which looked just as it had before—unscorched, unaffected. Gamow passed it around. It was petrified wood. He said, ‘That is where we are just now in the development of the hydrogen bomb.’
