And so are the walls and ceiling.  Wouldn't that make that game really hard to play?

At present the method for mitigating the destruction of lava flows is to place large concrete blocks in the predicted path of the flowing lava and spraying it with sea water in order to try and cool this molten material.
...
Instead of placing large concrete blocks in its path, I propose to create large casting beds into which the lava can flow



So how do you deflect a lava flow with a 6" pit?

And once you have filled a few cubic yards worth of casting area where are the other hundreds of cubic yards going to go?

The remaining cubic miles (do volcanos really only expel cubid YARDS ?) will surround your cast, encasing it for all time................

or get the dynamite

Only 3-4 blocks before it dissipates. Unless you're doing your casting in the Nether, then it can flow 7 blocks.

1. Hardened lava would be a terrible building material. 2. Lava flows are dangerous, unpredictable, and inconsistent in their flow. Sometimes it won't fill the mold, other times it will cover the mold, your equipment and the workers. 3. In no way is this an improvement over using concrete and concrete is more stable and less dangerous.

Not to mention that one would be building shelters right next to an active volcano.

Stupid idea.

2013-10-29 04:16:37 PM
the main issue would be that volcanoes don't always erupt the same  way. But if it was one that consistently lava'd you could build pits to capture the flow, but considering the volume of flow on some of the volcanoes I don't think this is a good idea

I'd probably try to fill up the lava with boulders.
Or a wand of frost.

Assuming you could figure out all the engineering challenges and somehow made a large enough field of forms so it is cheaper than concrete...

The material itself would be incredible inconsistent. Gas pockets, ash, fractures/faults, nonuniformity.

It might work as a decorative wall, but nothing structural.

if you could get a good pour of lava, it'd make some cool countertops or wall coverings

Or you could do what people in central Italy have been doing for a couple thousand years and cut tufa, volcanic stone which is extremely soft when fresh but which hardens into a solid building material.

On the upside (depending on your POV) people that work with lava tend to make mistakes only once.

No, but I stole my login name from a guy from out that way.  It was his favorite catchphrase when we worked in a lab together.

Unless that's an Archer reference I should know, in which case I feel shame.

You'd need a rather tame lava flow for this to work.

Even Hawaiian flows are notoriously difficult to divert.

And say you managed to fill a form, OK great - it's really crappy rock.  Did you include rebar?  Did it all melt?

No thanks.

If you're in a lava flow area, I'd say live in an RV or mobile home you can pull out of the way.

Fools. Everyone knows you put lava in a recessed ceiling niche and cover it with glass to make track lighting. And then have it pour down the walls in your obsidian throne room, because it looks awesome that way.

Movies get lava wrong every time.  They think it's glow-in-the-dark mud.

It's too dense for a human to sink into, and so hot one would explode into steam on contact.  It emits superheated toxic gas, and if it were ever inside a room, the contents would burst into flame and flash over very quickly and then burn out, with the lava pretty much unchanged.

You can't get anywhere near the stuff without getting cooked by the radiant heat.

You can get close to anything long enough to snap a frame and back off again.

Here's a realistic view.

I'd love to cast lava for artistic purposes. Not so much load-bearing applications, but I think it would be cool to cast molten stone into statues and weird shapes.

I was that close to the lava on the Big Island with poke a stick earlier this year and it was damn HOT!
