I understand the basis of the redox reaction occuring, but I am not certain 
why there are regions in a flame.  A picture I am looking at shows the lower 
pale blue portion to be the reducing region and the the upper to be the 
oxidizing. What is oxidized/reduced in these regions? As an extension, would 
it matter what part of the flame you put a sample in for a simple flame 
test? Thank you for your service.
