[Star Wars] If I'm marooned somewhere with sand or stone and I have my lightsabre, could I build a shelter out of glass or molten stone?

This occurred to me a few months ago, when I realized the importance of my lightsabre; as battered and "storied" as it is, it's actually a pretty impressive tool. Not only is it an offensive and defensive weapon, but it's a tool. I realized if I was ever marooned anywhere, I could use the Force to feed myself, gather water, but I could also use my lightsabre combined with my telekinetic talents to fabricate a shelter or dwelling.

If I were to use it to melt glass or stone, I could telekinetically move molten material into place and hold it until it solidifies. I could make a solid floor, thick walls and a roof, storage spaces and even a fireplace to keep warm. Obviously this would take time, but still. I've heard from another Padawan that sand is coarse and rough and irritating, and "gets in everywhere" <eyebrow rises>, but I think it'd actually be quite a useful thing, really.

What do you think of my idea? Could it be done? And you scientists out there, will melting all that sand and stone release any toxic vapour I should be careful of? You survival gurus, how should I construct my home to keep hostile animals out while I rest? Any additional relevant info would be appreciated.

Yeah, with enough time and practice you probably can pull it off. Just don't forget that power cell in a lightsaber is not infinite, and such prolonged application is actually one of few things that can drain the power from a lightsaber in a day or two. 

If you have a generator on hand to recharge it, then you'll be okay. But if you have a generator, then you probably have a survival kit too, which might have a tent in in for shelter...
