I've found that when I try to mine (or channel) obsidian created by adding water to lava, the result is a big explosion. Now, I'm not sure if this is normal (I've a feeling it isnt- if you know anything about it, please mention it), but I'm thinking that this could be used for some serious fun. One idea that comes to mind is a narrow corridor made of [explosive] obsidian at the entrance of the fort, manned by a vigilant dwarf lookout. When enemies pass through, this brave dwarf raises his pick and strikes one final, epic blow against the enemy... and is explosively propelled into a ready-made tomb, his final resting place, where all may pay tribute to the fallen dwarven hero.

I'd love to hear other fun ideas for how this might be used.

yay to my knowledge thats a bug, i have never  had that happen before.

Idea: see if when it falls it explodes on impact, then you could use it as falling grenades in hallways or something

I tried mining obsidian from a murky pool emptying into a volcano.
The miner teleported into the magma sea.

Are you sure it's not just the usual steam coming off of it from the result of the mixture?

[sdrawkcabcM tsirU]

Not at all normal, from my experience. But I haven't done much obsidian farming since a few releases ago. Wow, that would change my typically death-trap-like obsidian farming chamber (slick volcanic glass ramps and edges and potentially boiling hot waste water/steam) into a suicide room. Just imagine shards of volcanic glass shrapnel...

This "explosion" isn't, by any chance, unchanged lava pools mingling with water, is it? If there are steam clouds after this explosion, I'd bet that's the culprit.

I think I did something similar in the arena. If you put magma on top of water, it leaves the water alone, but forms a ceiling over it.

After some testing, it looks like that was the problem. Thanks!

Incidentally, I experienced this explosive setback whilst attempting to construct my fortress within a volcano. If anyone has any ideas on how to do -that-, I would love to hear them.

just try working with a volcano on a glacier, and the amount of work to create a farm without building in the caverns... Miners getting frozen/obsidianized.  Also all attempts to turn hfs into a massive obsidian block have failed to Glowing pits...

What does HFS stand for?

What does HFS stand for?

You must dig deep, and greedily.

What does HFS stand for?

You must dig deep, and greedily.

As long as you don't over-do it, and both at the same time. Maybe 20 z-levels, giggling like a schoolgirl whenever you find a gem. If you find yourself 140 levels down, cackling maniacally at the slightest sign of galena, you've dug too greedily and too deep.

[Malaclypse]

Ahhh, that HSF. I'm horrible with abbreviations. No, I'm not planning on making HSF solid obsidian.

My plan at present is to create a 20 z-level  obsidian fortress within the lava of the volcano at my embark site. Not only will this be an interesting defense, it will make for some definite fun at some point when something goes wrong. Not that I won't take every precaution to stave off said fun, which will make it all the more fun when the fun happens.

The idea is a lava moat... only rather than encircling the fort, it entirely envelopes it! Well, except for the entrance bridge/tunnel/tubes, which will also serve as the means of suspending the fortress in the lava. I think I may use windmills  to power the machinery within the fortress, if I can acquire the necessary number of nether cap logs for a submerged power transfer system. (It would use a set of gear assemblies and a horizontal axle submerged within a short channel of lava, with un-submerged gear assemblies sitting atop the submerged ones, followed by a second similar setup that uses water instead of lava, to ensure that nothing can enter the fortress through the power transfer tunnel unless it can fly, swim through lava, and swim through water).

I will try to incorporate a system of pumps that can flood or drain every major horizontal traffic passageway with lava, and construct all of the doors from these passages to other sections of the fortress on the roof- ie, the dwarves will have their rooms, workshops, etc. atop the passageways. In the event of a catastrophic breach of the outer defenses, the dwarves would retreat into these upper rooms (via burrow designations) and a lever would be pulled to flood all the passageways with lava, ensuring that either the dwarves will be safe from harm in their rooms while the enemy is dealt with by the military, they will be trapped alone and eventually starve when the military is slaughtered, or they will be trapped and each forced to face the horribly powerful magma-safe foe when it finds them cowering in their rooms. Fun.

Of course, this is what I would -like- to do. I know it is -possible- to do, but it may take a ridiculously large amount of time to accomplish.

Catapults. Catapults throwing obsidian.....
i want obsidian.
