    You can maybe cut it and give a better shape since its glass and theres tools for glass like an diamond blade (not to expensive, in brazil it costs 20$, so in USA it would be like 5$, and you can try search for an diamond grindstone if it exists, like the diamond from tools are made in machines with coal, so an grindstone may be not too expensive)

    10:32 what is that



  3. georgewahington on August 3, 2021 at 2:08 am

    So does this mean we’re not getting obsidian swords on minecraft?



  4. Codemaster28 on August 3, 2021 at 2:09 am

    This was so cool



  5. Gwyn on August 3, 2021 at 2:09 am

    Obsidian is hard, but hard doesnt mean resistent, its so hard that when you smash it with hammer it dont get smashed or bends, so the damage is not absorved, andnit goes for the object without anything for absorb it, so a iron may be more usefull, but obsidian make much better blades because it can be more thin than metal, the Aztecs used wood swords with obsidian blades for fight against Spanish People, they said that with one attack someone litteraly cutted off the head of an horse, with one fricken hit



  6. WolfricLupus on August 3, 2021 at 2:10 am

    Obsidian is by definition volcanic glass. The moment you melt it to process it, it is no longer obsidian but a synthetic glass, particularly with the added ingredients whether they be flux or metal.

    You are an insane contributor to green house gases by the crap you make, and keep remaking and remaking to get some likes on youtube. Consider what you are doing.



  8. Alex Bynum on August 3, 2021 at 2:14 am

    Heat the vermaculite before you add the obsidian.

    Man makes netherite in real life



  13. FanboyGamer 3E on August 3, 2021 at 2:20 am

    Someone add this to a Minecraft mod. I don’t care which version, just do it.



  14. Crassus Licinius on August 3, 2021 at 2:21 am

    Obsidian blades are very sharp but incredibly brittle the way the ancients forged obsidian arrow heads and blades was by smashing another piece of obsidian against the piece your working on until it chipped in a sharper shape then the edge was honed on more obsidian ..A very long process but bcuz obsidian breaks so easily it might be the best way to go about doing it



  15. ahmog on August 3, 2021 at 2:25 am

    now i know Elder scrolls glass weapons are crap



  16. Bryce Vandiver on August 3, 2021 at 2:26 am

    Skyrim lied to me!

  19. Mel Ullom on August 3, 2021 at 2:28 am

    I have a obsidian rock. It’s black and smooth and shaped like a dog skull. I call it stripes because of its huge black stripes. I found it at a friend’s house in their river yesterday and it’s the first proof that my friend lives next to a ancient valcano.



  20. Tooploop on August 3, 2021 at 2:28 am

    i don’t think you understand how flux works



  21. Erik Iacopelli on August 3, 2021 at 2:29 am

    Now we all know NEVER EVER let you touch our tools or anything else for that matter! Lol



  22. Nivit Mishra on August 3, 2021 at 2:30 am

    The number of times I have been recommended this is more than the temperature needed to melt obsidian



  23. Patrick Sweeney on August 3, 2021 at 2:30 am

    irl jack smith



  24. Chris Hansen on August 3, 2021 at 2:30 am

    add some lead.



  25. Darren Osbourn on August 3, 2021 at 2:32 am

    Yea like if that’s in a honey jar I would eat it



  26. DanY4real on August 3, 2021 at 2:35 am

    this is why you can’t make obsidian tools in minecraft



  27. حمدونز في حمدونز on August 3, 2021 at 2:37 am

    The portal is good actually

  30. Aj T on August 3, 2021 at 2:38 am

    Not gonna lie, an obsidian sword is something i would very much love to get my hands on



  31. Tannim Kyraxx on August 3, 2021 at 2:38 am

    how many kiln’s have ya’ll killed to date?



  32. John Free on August 3, 2021 at 2:39 am

    Stick to weed friends….



  33. Noah Jenkins on August 3, 2021 at 2:39 am

    Is obsidian heavy



  34. This comment will probably vanish. Ask google. on August 3, 2021 at 2:39 am

    "it was questionable as to whether it could be considered obsidian anymore"…. /Adds stuff to make it look black… "Now that we have obsidian…" Hahahahaha!!!!



  35. Ryan Lebeck on August 3, 2021 at 2:40 am

    40% obsidion, 60% charcoal.



  36. danjf1 on August 3, 2021 at 2:42 am

    thats why our ancestors only used small amount of pure obsidian and not in sword form – too brittle. but interesting concept



  37. Mr H on August 3, 2021 at 2:42 am

    Try an axe it will probably be easier since you just need to make a head



  38. j c on August 3, 2021 at 2:43 am

    Should of preheated the mold / sand / vermiculite



  39. Mr. Conservatarian on August 3, 2021 at 2:51 am

    Powder flux? I didn’t know that exists.



  40. Sparrow Miller on August 3, 2021 at 2:53 am

    that shit at the beginning is cursed coffee



  41. R H on August 3, 2021 at 2:53 am

    It’s not gonna be great for a sword, because in casting it like this, you no longer have a grain structure. Thus, it will simply shatter



  42. S R on August 3, 2021 at 2:56 am

    that happens when idiots have too much time and eauipment, read a simple list in a lexicon or online, obsidian has a melting temperature…case closed…work in that temp. range amd it works, with about everything…if it can oxidize you need a reducing atmosphere, if you donlt even know that give up and go back to middle school…



  43. a hacker that misses every single shot on August 3, 2021 at 2:56 am

    You can apparently melt obsidian using a blue flame because it reaches up to 3000 °F



  44. Soul Stuff Library on August 3, 2021 at 2:56 am

    Coming here expecting: "powerful ultra sharp blade, that can cut trough hardest things"

    What do I get: popsicle.

    Interesting stuff though, great work!



  45. Lou Bustos on August 3, 2021 at 2:56 am

    How about letting it cool in the daft clay mold (both sides)? or lost wax mold. Since the lost wax mold is already hot (900 degrees) it should cool down slower and allow the glass to set up more firmly. Just a thought-

  47. MexicaFluentGamer on August 3, 2021 at 3:00 am

    Add jade and maybe it will work



  48. Pj on August 3, 2021 at 3:04 am

    what is the point of it over 50% flux? defeats the purpose
