Thought I'd throw this in here. The other day, clear skies, not a cloud in sight, the sun had just appeared over the roof of the house opposite, my daughter getting ready for work had her blinds open so she had natural light to apply her make up, she the went to make a cuppa and when she went back into her bedroom she could smell burning, hunting down the smell, it turned out her concave magnifying make up mirror she had left on her dressing table, had been left just so, that when the sun hit it, it made a perfect small (I'd guess less then 1/4 inch diameter) circle on a nail file, the edge of which was black and smouldering.
Not entirely certain it would've caught fire, but had it been on something more flammable it might have been a different story.
