Bolt/Fire Damage stat on weapons

I've been really confused about this since I started getting my first attribute adding gems.

I am getting gems that add fire/bolt damage to a weapons. Still, adding that gem to a weapon doesn't activate flame/bolt visual effect.

I am wonder if those elemental damages actually work if the appropriate paper is not activated. For instance does a sword with +20 fire damage gem add the fire damage to each hit or does the +20 only increase effect of fire paper?

Also, assuming I use a weapon with fire damage gem, but no fire paper, do oil urns make the fire damage more effective?

Does Bolt damage scale with arcane?

Arcane is a stat in Bloodborne. It increases the damage done by Fire and Bolt damaging Weapons and Items.

Does Bolt and Fire paper scale with arcane?

Same with bolt. It does two things: converts all damage from the weapon into elemental damage and converts the scaling of the weapon to Arcane. This usually significantly reduces the amount of damage you do with the weapon, in favor of scaling off of Arcane and doing elemental damage.
