Normally Liquids only have flash points......In some cases, flash point also can be determined for solids, its value depends on type of solid.

Cardboard hasn't a freezing point.
Class 3 flamable liquids
Antifreeze is Highly Flammable! But its flash point is around 240 degrees Fahrenheit.
The flash point is the temperature at which a liquid gives off an ignitable vapor. It is NOT the smoke point, nor the ignition point. Unrefined peanut oil has a smoke point (temperature at which it begins to break down, give off smoke) of 320 degrees Fahrenheit, while refined peanut oil has a smoke point of 448 degrees Fahrenheit. The ignition point of both oils is 700 degrees Fahrenheit, and the flash point 600 degrees Fahrenheit.
It depends on the substance. Yes, all flammable substances have a "flash-point". Every substance has a different flash point expressed in degrees Celsius or Fahrenheit. If the temperature is below the flash point you will not be able to ignite it. And the higher the temp above the flash-point the more readily it will burn.

Class 3, Flammable liquid, has a flash point of not more than 60 degrees C.
Kerosene is considered to be highly contestable. Kerosene has a flash point between one hundred and one hundred and sixty-two degrees Fahrenheit.
