Everything

By using Prime 2, a mage can pull a single point of Quintessence from an object that’s being ritually destroyed as part of a sacrifice. Despite the phrase “burnt offerings,” that object could also be broken (like a glass smashed under-foot at a Jewish wedding); dissolved in acid; dropped in the sea; scattered into the wind as ashes or dust; buried without intentions of digging it back up; or otherwise surrendered to the act of sacrifice.

By combining Matter 2 with Prime 2, you could draw out one Quintessence point per success on your Arete roll. In either case, the Effect is coincidental – people can’t see the Quintessential energy unless they have the Prime Sphere, although someone might sense the energy-transfer if she’s got Awareness. In either case, the act of giving up that object is an essential part of the spell. No sacrifice, no Quintessence.
