How does Material Exchange work?

I have the option of trading in some Spirit Bloom (or any of the other materials—Spinmetal, Helium Filaments, Relic Iron) with the Crucible Quartermaster (I believe some other vendor does it too), but it gives me no indication what I’d get in exchange. I imagine it’s some amount of rep and perhaps marks, but what is it? And if it’s variable, what are its deciding factors? Do all kinds of elements have the same conversion rate?

Note: As of the December 1st update material exchanges now work in the opposite direction, where marks are used to purchase materials.

    You can use 10 legendary marks to purchase 20 of any planetary material from the Vanguard Quartermaster. See below to locate the quartermaster.

    Faction rep (per each of the 3 factions: Dead Orbit, Future War Cult, New Monarchy) can be gained by speaking to the respective faction rep in the tower, as seen on the below map. The exchange rates are as follows, gaining rep for the faction rep you exchange with:

    5 Motes -> 100 rep

    25 Weapon Parts -> 50 rep

    25 Old Armor Materials✝ -> 50 rep

    25 Unified Armor Materials -> 50 rep

    Special Ammo Synth -> 25 rep

    Heavy Ammo Synth -> 25 rep

    Old Armor Materials includes Plasteel Plating, Sapphire Wire, and Hadronic Essence.

    EDIT: The below exchanges are no longer valid as of “The Taken King”, September 2015.

    You can now go to the Vanguard/Crucible Quartermaster and exchange 10 marks for:

    20 Spinmetal

    20 Helium Filaments

    20 Spirit Bloom

    20 Relic Iron

    The Crucible Quartermaster is in the middle area of the tower before the class Vanguards (opposite Lord Shaxx). On the map this is in the blue area near the icon that says Crucible.

    The Vanguard Quartermaster is in the area near the shipwright. On the map this is in the red area and marked Quartermaster.

    EDIT: The below is no longer true as a of a patch in late 2014.

    Each time you exchange 50 of each material to either the Crucible or
    Vanguard Quartermaster, you get:

    +5 Crucible/Vanguard Marks (as long as you’re below the weekly limit)

    +25 Crucible/Vanguard Reputation (these change if you have a faction class armor equipped)

    +250 Glimmer

    Note that you are also capped at 200 total marks for each faction, and
    100 per week for each faction.

    These answers are all from before the end-of-year patch. Now, materials exchange only works the other way: you can buy materials, but you can’t sell them.

    You also get 250 Glimmer for each 50 Material…and 5 Marks, and 25 Reputation, as satated.

    I think if you wear a Faction Mark/Bon/Cloak the marks/rep gain goes to that faction instead of Vangurd/Crucible.
    Not sure though, I haven’t tried it.
    Though I do know doing Patrol Missions with a Faction Item worn gives the reputation reward to the faction you are wearing.

    I traded in 50 spin metal and got one mote of light. 50 spirit bloom and got 250 glimmer 5 crucible marks and 25 rep.
