Ed I just lit up a piece outside , it burnt right up till it was gone. I
have 4 types in my house, I bet they will all burn up completely with my
Bic lighter


Did you remove the flame? Yes, it will burn as long as there is a source of
ignition. When you take away the source, it will go out. Assuming you are
using insulation grade material. I've been doing that test frequently for
the past 35 years on hundreds of batches of material and it has never
failed.
