Gatherer/Artisan Class

[Elf Spice]

I'm thinking about getting level 5 with both Gatherer and Artisan in Daemonheim, and I have a few questions:

 

Does the extra resource effect for Gatherer work like Varrock Armor? (chance of double resource) Also, does the artisan ring only work on skills affected by artisan potions, or does it work every time resources are processed? For example, do I have a chance of saving:

 

-ores, when smelting bars

-bars, when smithing weapons/armors

-herbs when mixing into a vial of water

-secondaries, when mixing with an unf pot

-Rune essence, when crafting runes

-Charms, when making pouches

-Hides, when making ranged armor

I'm unsure about artisian but gatherer works the same as varrock armour in that you get one resource, get the xp for it, and have a chance for getting a second.
