i dont burn anything... i may go out unless you throw wood into me, i may cook things if they go in me for long enough

I have hundreds of teeth but cannot bite. I am shattered into pieces before I am whole, And the more of me you find, the less of a gap remains.

What has ten letters and starts with gas?

I rise and fall as boats stall over mountain ridges and trolls fidges stone by stone built up in rome just to fall back down in london
