“The flame spread rating of a piece of kiln-dried spruce might be twice that of red oak, but it is exceedingly difficult to ignite, say, a 2 x 4 with anything short of a large fire. Just try lighting a piece of timber with a blowtorch; it goes out when the flame is removed.” – John J. Lentini, Scientific Protocols for Fire Investigation, Second Edition
