Farming Popular Mats

So we all know that certain mats (stacks) create quite a lucrative farm for most people. But some of us have problems gathering them, whether it be location or build. So I have created this thread to form a list of possible farming locations for certain mats.

If you have any locations, quests or builds to contribute to this, please do.

COMMON MATERIALS:

Feathers:
Jaya Bluffs: SoS spirit spammer (any caster can do this)
Naphui Quarters: SoS spammer (again, any caster)
Kryta birdies: SoS spammer (any caster)

Iron Ingots: Farm max weapons and salvage them. Here are some places (HM)
Vaettirs in Jaga Moraine (A/Mo vaettir farmer)
Raptors (W/N Raptor farmer)
Other easy-to-farm mobs (trolls, hydras griffons etc.)

Bones:
Gates of Kryta (NM) (Any/Mo GoK farmer)
Jaya Bluffs, bones drop from the birdies as well as the feathers
^ on that note, Naphui Quarter as well
^ and again, outside of Lions Arch

Piles of Glittering Dust:
Gates of Kryta (NM) (Any/Mo GoK farmer)
Salvaging Demonic Remains, Phantom Residues and Demonic Fangs from Topk, UW and FoW


So thats what I can think of right now, I'll add some more mats later on as well as start rare mats, but if you have anything to contribute, please do.

Thanks jaya bluffs can be done on almost any profession - ive done it using a fire nuke ele , standard 55 build on a non 55hp monk , 55 monk build , vwk me/rt and rt/me.And vaetires are also doable on a/me , me/a , e/me (several variations ) and mo/a and i believe w/n with bonder as well as in theory a n/a and a/n ( theory tested a/n and was very slow - different but slow as hell lol ).
Fahranur explorable nf in hm - i believe mo/d 105hp will do skales/undead for iron/dust and bones ( plenty of dead swords/dead bows and skel shields ) - the build i recall isnt standard 55/105 - uses ps,mystic regen , and sigs for dmg and you rely on ps/mystic to keep you alive.If anyone knows the exact build and would be kind enough to post i would be grateful.
