Trine, you need to read the very first line of the section you are referring to in the PHB (p150)

Which prompts me to ask why you think that the spells I quote explicitly say that they will ignite certain things, eh?
Unless the descriptive text for the spell specifies otherwise, all items carried and worn are assumed to survive a magical attack. If the character rolls a natural 1 on his ST, however, an exposed item is harmed (if the attack can harm objects)
