I really, really hope so. Here's wishing they'll continue developing the world in a playable (video game) format next, including being able to train/level your character by taking classes at Ba Sing Se university.

These numbers are for the "raw" states of metals, as in their average concentration in ore or other natural sources. They can be refined down to almost 100% purity. (You can buy 99.999% purity Mercury on the internet.) Since these are pure elements we're talking about, not compounds, it's important to remember that any reference to them by name should implicitly mean 100% purity.

Hoorah! Titanium alloys are insanely strong (inflexible/unbreakable) for their weight class, making them one of the reasons they're favored so strongly as medical implants. For example, I have 1 meter of titanium rods and 26 titanium screws and they only add an additional 2 lbs to my body weight, whereas Tungsten steel would add nearly 10 lbs to achieve the same result.
<p>There is the possibility that chemical elements in the Avatar world don't correlate to the ones we know, so "platinum" to them may well be what we would call a high-purity alloy. Or perhaps, given the rarity of platinum, they just thought it would be less likely to be questioned. (Whereas titanium is actually rather common.)
</p><p><u>In regards to Mercury:</u> we've seen Toph and Katara work together to separate mud/pollution from water and have even seen Toph mudbend without any qualms. Therefore, it seems to me that any metalbender would likely be able to bend Mercury in the same fashion. The problem is that the writers needed an "unobtanium" and therefore threw in the inability to bend a "pure" metal, causing this issue.
</p><p><u>In regards to "pure" metals:</u> to me all evidence points to this term referring to the purity and uniformity of the elemental matrix of the metal rather than it's actual (chemical) elemental proportions.
</p>
<dl><dd>When Toph metalbends for the first time, we get a glimpse of how she perceives the metal, including the "impurities" which she is able to exploit in order to bend the metal.
</dd></dl><p>From this we can extrapolate that the electron cloud of metals has some effect on their bend-ability, with the most likely postulate for this being that the electron cloud acts as a type of shield against bending. Impurities in the metallic matrix cause distortions in the cloud which may possibly then be used as anchor points for the bender to exert their control over the metal.
</p><p>-sigh- When are they going to publish a "Subatomic Guide to Bending"?
</p><p>Thanks for reading, and I hope this was both helpful, informative, clarifying, and provided further fuel for this and other conversations.

<p>This is the absolute truth. The show gives no corroboration for why platinumbending is extraordinary.
