Suppose you take an ice cube tray and use petroleum/gasoline to freeze some blocks of it. What would happen if you:
a) placed a cube above naked flame; or
b) threw a cube against a surface which caused a spark?

The liquid melting off over the flame would burn, but the cube itself would not ignite. Throwing it at a surface wouldn't cause a spark, unless you froze a steel nail into it and threw it at wall made of flint, in which case the cube would shatter and the nail would spark to no avail.
