Neanderthals used chemistry in fire-making?

Thanks to Pandora from alt.anthropology.paleo for sharing this paper:

Selection and Use of Manganese Dioxide by Neanderthals 


Several Mousterian sites in France have yielded large numbers of small 
black blocs. The usual interpretation is that these ‘manganese oxides’ 
were collected for their colouring properties and used in body 
decoration, potentially for symbolic expression. Neanderthals 
habitually used fire and if they needed black material for decoration, 
soot and charcoal were readily available, whereas obtaining manganese 
oxides would have incurred considerably higher costs. Compositional 
analyses lead us to infer that late Neanderthals at Pech-de-l’Azé I 
were deliberately selecting manganese dioxide. Combustion experiments 
and thermo-gravimetric measurements demonstrate that manganese dioxide 
reduces wood’s auto-ignition temperature and substantially increases 
the rate of char combustion, leading us to conclude that the most 
beneficial use for manganese dioxide was in fire-making. With 
archaeological evidence for fire places and the conversion of the 
manganese dioxide to powder, we argue that Neanderthals at 
Pech-de-l’Azé I used manganese dioxide in fire-making and produced 
fire on demand.

I have often thought that if a Neanderthal travelled forward in time and found himself in 2016, he would think us extremely primitive.
"What? You need things to condition the air? Why not just tell your body what temperature you'd like?
You mean you spend all your time doing something you hate so that you can eat and have shelter? Why not just chase down a deer and sling it over your shoulder?
Why do you need all of this crude metal to do things that you can do with arm and brain power?'re spending how much to reach Mars? Want me to show you how to do some astral projection? It's cheaper, really, and quite simple..."

Yes, I would like you to teach me astral travel with this! Seriously, it is a question I have often wondered... How did the Neanderthals astral travel? I knew fire and manganese dioxide were involved, but that's all. Can you help?

I would recommend the writings of Stan Gooch, he's tapped into Neanderthal mental processes better than anyone I've read.
