well as a child i was using a magnifying glass to burn different materials, wood, matches, and god help me, insects!!! but one thing that would not burn at all no matter how long i held the beam on it was an ordinary white paper plate. i don't know if that helps to answer but there it is. not enough heat was being absorbed into the material to ignite, and the reflection was too intense to look at for long.
