Soulcast aluminum

[Shqueeves]

In Mistborn, a fact that is driven home countless times is that aluminum can't be pushed/pulled. In Emperor's Soul, ralkelest (aluminum) can't be soulstamped. However, in WoR, it is revealed that the only way to get aluminum on Roshar is via soulcasting. What do you think?

The real question is if you can soulcast something into not being aluminum. I suspect this is a "you can make a boulder heavy enough that you can't lift it" situation.

Completely agree. You can change the structure of something to become aluminum, and once it becomes such, it can no longer be effected directly by investiture. 

I'm still more intrigued by who introduced aluminum to Roshar, as in order to soulcast something, you have to know what it is.

I made sure to mention that uncertainty when I added the Roshar subheading to the Aluminum page. I think that you can't, but without proof, we don't know.
