Yeah, ice is made from water and water has oxygen and hydrogen in it that makes it combustible, but you are going to use up a LOT of matches and disposable lighters trying to set it off without compressing in in the core of an explosion.

No water is NOT "combustible." Gasoline, natural gas, diesel fuel, propane and hydrogen all burn to produce carbon dioxide and water. So water has nothing to burn. Try it with your tap water. Use as many matches as you wish.
Here's a thought experiment: Why is water used to put out fires if it burns?

@DeerSlayer
All water is not the same.

With some fires, water is the last choice. Combustible metals (Magnesium, for example) burn at temperatures which will dissociate the atoms in a water molecule, adding hydrogen and oxygen to the fire. That's what class D fire extinguishers are used for.
thackney:
The ice itself does not burn. The methane trapped in the ice lattice is released with heat and the methane burns.
The water does not break the bonds and become hydrogen and oxygen. It just melts to get out of the way.
