Copper Pouring Steam Explosion

[MrEddyilbello]

oh men ... you have a big balls and cold blood ... i at the firt explosion sent at the next day

[rubenswitzer]

PREHEAT THE MOLD

[sambath92kumaar]

wow...

you should have dried the mold before pouring the molten metal into it...!!!

I think the water in the sand of the mold evaporated instantly...!!

[stimps90]

Dry your molds dudes lol

[xarlock667]

If the mold explodes once, it is a GREAT indication you should stop using it. If the mold explodes twice, it is a WORLD CLASS indication is time to stop using it. If you use the mold a third time, you deserve what you get. That was just stupid. Maybe you need to get burned to the bone once or twice and loose some fingers or toes to learn, but I suggest you note errors the first time and then stop making them then.

[mike4ty4]

@xarlock667 Why do they "deserve" it? If they're too stupid, it's their problem and theirs alone.

[pattycackespattywack]

that is just fucking dumb... three times?

[htirah100]

thats a big crucible

[rolficus]

well done assholes now your bullion will look like swiss cheese

[IwillhonorGod]

is this a prayer meeting?

[ryman1075]

lol, "um...let's not do that again..." Classic :)

[baseball90995]

Let's not do that again lmfaooo

[h2omadman]

lol @ 0:17 bad kitty

Molten copper and aluminium will send you straight to the hosipital. This isn't like casting your own lead bullets. These highly conductive metals ( electrically and thermally ) will transfer all their heat to your skin instantly. Copper is particularlly bad because it has such a high melting point. These guys were extremely lucky. Always bake your molds thoroughly to remove any moisture !

[Banana666]

"Ugh, lets not do that again.."

epic comment

[bastardchildofmary]

it might help if you make the mold bigger and vent it

[moosey333]

Yeah you have to have the molds heated before you pour. Then keep heating the insides with a blow torch to be sure.

[timw421]

when you are making ingots you do not use water at all it will blow up even after you pour it, trust me i have before

[SgtAndrewM]

why did you put it in water? don't you put the water on last.

[jmw1980hys]

Stuff like that will happen when you are doing this, but ...... where are the thick leather gloves, apron, mask, and steel toe slipons. When your working with a crucible that big and have something go wrong..... You can die from it!!!!!!!

[ab48726]

Ahhh... reminds me of the steel foundry days... LOL, nice try anyway. Everything looks great up until the wet mold part. That's a lot of copper!

[napkingcole]

"lets not do that again" hahahahah priceless tone

[chorizoe]

Dude that could have seriously burn somebody!!! Any moisture in the mold could produce a violent reaction specially with copper that melts at a higher temperature than most alloys. I would suggest heating up the mold before pouring! And when pouring, do it really slow so the metal doesn't pop like that!

[svenp]

"um let's not do that again..." How many times have I heard that one. Heheh.

[swomplode]

I don't have time to watch this whole video right now, but I can tell from what I've seen so far that what you have there is a situation where water has gotten into your molten metal. This water has turned into steam and violently bubbled to the surface, resulting in a small explosion. You're going to suffer some third degree burns when that metal hits your skin. You need to get some ice on those wounds immediately and get some iodine on there as soon as possible before the infection sets in.

[pattymatic]

Wow. Thank you for pointing that out as if it wasn't immediately obvious to everyone. You must be some kind of super genius.

[swomplode]

No problem.

[brierejoe]

Maybe you should have watched the video before commenting on it. I didn't see or hear anything about anyone actually getting injured. You sound like a moron anyway.

[griffin66441]

You don't have time to watch the whole video? But you do have time to type this long ass comment?

[m15cell]

Can you guys please post instructions on how to build a furnace like yours at w w w .instructables . com?

[desinfector]

look@ my vids...

nearly the same there but i was melting a silver-alloy (like a noob).

[Alexharcourt]

Maybe wear a few layers of protective suits or something. That way if something goes wrong you might be able to strip out of the suit before it gets your skin or at least give it a chance to cool bf it gets to you.

[ginarific]

Omg it exploded the first time and you guys did it AGAIN? -___-;

That was SCARY.

[alexcorn]

Yes, it was scary. I thought it was done exploding... I was wrong :-P

[NedBurchfiel]

@alexcorn Ah yes . . . famous last words. But that ambition will get you far in life.

[badwolfshamma]

@alexcorn the air bubbles inside the brick heated up and pressure caused it to explode

>>>>scientist<<<< year 9 uk british guy explaining what happend lol

[alexcorn]

@badwolfshamma There was no brick. But thanks for your input.

[badwolfshamma]

@alexcorn sounded like brick exploding



[kahlzun]

Water apparently expands about 1600x when evaporating, so an almost gunpowder-like effect can be reached

[creten69]

did that burn him?it would hit your skin and go through the bone,thats funny,it reminds me of hell,only not as hot.

[richardphat]

Ah good to read this!But still why the molten copper splash?

[alexcorn]

The mold was made of steel and sand. The sand happened to be wet. When the 2400F (1300C) copper touched the wet sand, the water in the sand boiled immediately - the water exploded into steam.

[richardphat]

Oh, and since it is done at night you cant see anything

[alexcorn]

Well, you can see the little particles of molten copper flying everywhere. You can't see the steam, though. There probably wasn't any steam to see anyway. It doesn't take much water to explode and send the molten copper flying.

[TheMrBlinx]

@alexcorn Ever hear of "out gassing"? Warm the mold up for a few hours and let it out gas and dry good before you pour. It's dangerous enough in daylight, why add to that danger by doing it at night?

[infamoussafg]

@alexcorn wait how did you make the mold?

[richardphat]

Omg are you guys all right? I hope nothing happened to you and your friends

[alexcorn]

Everyone was fine. The molten copper didn't hit anyone. We were lucky.

[Pyrotecnican]

When I was melting lead some weeks ago, the same happend, but I got it everywhere! I had to cut some out of my hair...=(
