Title: Can volcanic glass start a fire?
Post by: Mearns Learner 1 on 06/08/2010 14:30:02

Mearns Learner 1  asked the Naked Scientists:
   
Hi there, might it be possible to start a fire using strands of Pele's hair - a geological term for volcanic glass? I believe it is possible to focus the suns rays using an ordinary piece of glass.

Pele's Hair is often found in an uncoloured state - clear.
 
Many Thanks
Bert

What do you think?

Yes, it is possible, just as if you were using a magnifying glass.

I would add, that you are more likely to get a sort of lens from Pele's tears rather than Pele's hair...
