Becky,
As Len notes you really be a bit cautious as to what you set the chimney on. If I'm grilling and lighting a bunch of charcoal I do what Tim suggested. Most of the time I'm just starting a small amount for a minion,
so I end up with the chimney on a piece of slate.
While newspaper works fine (with or without oil), I use a one "starter cube". I just find there is a lot less potential stuff blowing about: Nice & clean.
Something else to consider, is to flip the charcoal grate over in the chimney.
It makes it a lot easier to get a small amount (or even a large) ignited.
