[Avatar] Is it possible to glassbend?

So it's been shown that it is possible to bend sand. When sand is melted, it becomes glass, but it's still made of the same stuff that sand is. It's a molecular change somewhat similar to the difference between water and ice. 

So could a sufficiently talented earthbender bend glass? Could they, say, take the glass, grind it into powder, and bend glass powder like sand, but much deadlier?

I would think that they can. Much like how Earth Benders can become Metal Benders, or even Lava Benders, it follows that they should be able to bend Glass.  And even thought glass in solid form is more brittle than metal, I'd bet that Glass Benders could reshape glass to fit there needs. 

It's be interesting to see how they fight with that ability.
