[RPG] About Spell Scrolls’ mechanic, how do they work


This question is bothering me, my dm couldn't answer it.
What is the difference between a spell scroll and a page of spellbook? One goes "puff" after use while others stays permanently. Also I'm curious about this puff effect, something like the content vanishes or paper burns up?

A spellbook contains the formula for a spell. A scroll contains an almost-completed casting of a spell - the equivalent of what you would prepare for the day, in written form - just speak the completion of the spell to activate it. When you complete the spell inscribed on a scroll, the contents of the scroll are erased, just as the spell is erased from your mind, when you cast it.
