In minecraft, you need Diamonds(the strongest tool material in the game) for *THIS?!?!* I can see why there's no obsidian sword in the game. Wait, then why is gold (a super brittle metal) in the game?

there is some chemical reaction in obsidian that just keeps on bubling when melted until there is just a small bead less than 10-12mm D and even that will most times crack as it cools.youll have to ask a geo or chem professor what,? i dont know but have tried many times with same result..only way you will get what you want is to carve it out of a solid block of stone which is probably how the original was made. or maybe put it in a high pressure chamber till it is cold.expect it to have fine surface cracks at the very least.

Too bad it didn't work. Even if it had I fail to see any advantage to a glass sword unless you are the kind of guy who would stab a dude deeply then hit him so the blade shatters internally. What a nasty death! lol Clarification: I should say "Standard glass sword". I think some of the modern glasses could be used as a sword blade.

I like this young lads pioneering spirit. I hope he does not give up. I wonder if any one has explored all the options of working with this sacred material obsidian. Like forging his casting when in the fluidic state and using techniques . I would so cool to have a ceremonial obsidian sword.

You can't cast obsidian becauseto be obsidian it must be magma(mineral matter) that rapidly cools so it doesn't have time to crystallize
That was really cool to see all of that. I have some obsidian in my back yard and I know what I'm NOT going to be doing with it!! lol interesting to see what it did though, the part when u put the solid pieces in and it over flowed and grew like it was alive!! That was cool. Well it was very not cool actually was extremely hot but you know what I mean! Lol cool video thanx!

You might try a hardened carbon casting (with fine layer of powered carbon) in a heated titanium shell (the titanium shell will transfer heat quickly and evenly into the carbon which will not emit gas into the molten obsidian). Titanium melts at around 3034, and even as a very thin outer shell will transfer heat in or out quickly and hold shape. The problem with obsidian (as well as glass) is that there are heavier and lighter particle densities within. In order to even other these particles and get a better binding, vibrate the molding even as as the molten obsidian is being poured, and reduce heat to the mold slowly. The vibration will cause bubbling that occurs within the obsidian to release more efficiently, the hardened carbon molding within the titanium shell will hold its shape. If heat is removed too quickly, ( exposure to water vapor in the air, humidity) the exterior of the obsidian will cool faster than the interior which will cause breaking. In order to prevent this, reduce the temperature of the mold slowly while maintaining vibration of the mold. Particles in motion lose heat faster, which is why to keep the mold sealed and heated, not removing the product until the internal temperature is well outside of molten point, about 160, as it is obsidian, you might want to let to finish cooling naturally within the carbon molding. The particle density of the obsidian should be more even as it was kept in vibration, not allowing gravity to make the bottom denser and the top thinner, even particle distribution will ensure .... should ensure a more even cooling with very little if any bubbling occurring within or even on the surface of the obsidian. You will want to make the edges thicker and not have them taper off to a thin edge. I know glass with too many impurities tends to get brittle the farther you get from the center of cooling, and I assume obsidian which comes from ryolite... rhyolite? comes from something... (lol) is not exactly pure silica, well, I know it is not pure silica, but I do know it was formed from volcanic activity, pumice or whatnot, it was under pressure, and it cooled over time as the temperature of the rock cooled around it. Layers were laid upon layers, flowing molten at uneven temperatures, and even as it was cooling it was likely in motion. I was going to make a point here but my mind wandered.... sooo If you keep it under very slowly reduced head, allowing the center of the obsidian within the mold to cool more naturally and much slower, and keep it under vibration until well below where the interior temperature should have completely solidified, the interior will not be more swollen than the solidified exterior which has compressed itself around the larger as yet uncompressed interior (which is often the cause of exploding glass marbles, exploding as the interior is essentially larger when it cooled as the exterior cools first.) In all, doing it this way should make your obsidian blade far stronger and easier to hone to a blade edge. Lastly, the loose carbon layer inside the mold will likely coat the product nicely, and should polish off easily, but I do not know obsidian well enough to assure myself that I am correct, I do know hardened, and tempered glass however. I also know myself and sometimes I say things backwards in such a was as to not make sense. My assumption is that obsidian is brittle because the layers of cooling occurred from top down, the bottom layers flowing under, and the high probability of gasses in and around from numerous impurities. The layers would then tend to create thinner compressed edges which would mean hardened and sharped layers even as each outer layer is removed (via chafing). In trying to pour and mold this impure glass you are not really doing it as was done naturally, but maybe by treating it in a more natural manner (constant motion until it is cooled enough to be a solid form, and has cooled very slowly) while creating maintaining the purity of the obsidian that nature could not provide, you may very well be able to craft an excellent obsidian blade that should be quite durable.

kind of debatable if it is still obsidian?? there is no debate, you changed the chemical composition so no, its not obsidian.

Obsidian is pretty easy to make! Just place a bucket of water and a bucket of lava and you have obsidian. Just use your diamond pickaxe to mine it. Having an Efficiency enchantment in your pickaxe can make mining faster. The only problem is that obsidian swords are not yet implemented.

The best way to melt obsidian or any "unmeltable" substance for casting or to form an alloy is to use an arc welder. Using a couple graphite rods and a graphite crucible you can melt just about anything your power bill can withstand (maybe try a generator). In this way you can form your alloys in the crucible or layer it in the mold. Give it a shot some day, I'd love to see your results.

I actually learnt that you have to use an annealing oven from a book called Fire Study by Maria V Snyder, a character makes glass animals.

Thing is... what makes obsidian special is it's crystalline structure, not the material per se. If you really wanna cast real obsidian there should be a special level of pressure and slow cooling so it becomes compact enough to produce a sharp edge. I'm in no way underrating your findings but if you were interested at coming back to this project one day there is def the need for some pressure
