How To Melt Gold
Watch this video if you want to learn the procedure of melting gold at your home by yourself. Follow the steps and measures mentioned in this video to ensure a safe experiment.
Today, we're going to melt gold. Now, this is not highly dangerous, but you've got to have all of the right safety precautions and things around to be able to do it. The equipment that we're going to need are things like, you need some metal tongs, okay, you need some safety leather, safety gloves, okay, to protect your fingers.
You need this gold to melt, that's 2.7 grams of gold. You need a crucible which is this thing here, which is usually either made of graphite or some kind of white material like this, it will go to very high temperature to about 1,500 degrees.
You need safety mats; this safety mat here will go up to a couple of thousand degrees and protects the desk that I'm doing it on. So, it's the gold there, you need some goggles, safety goggles to protect your eyes. And also, on the side here, we have a bucket of sand just in case something gets a bit too hot and you need to put fire out, we have fire extinguisher and we have water as well, so that we could put the gold or this equipment in, so as to put it out if there was fire.
So, we've got lots of safety equipment here. That's the most important thing we do now since what we're going to have to do is heat up this gold to about 1,000 since about 1,060 degrees is really hot. And the temperature at which gold melts is- well, pure gold melts at a very high temperature, it melts at about 1,060 or something like that.
But then, less and less pure gold melts at lower temperatures. So, if you've got this 24 carat gold, but if you've got 9 carat gold, it will melt at lower temperature; if you've got 18 carat gold, it will melt somewhere in between. So, let's see how to get it.
Safety goggles. You can light a butane torch here, quite easy with matches. Butane torch is what jewellers use for melting gold or other types of torches.
So, let us light the torch. Just sate! You can hear the torch. You can hear that it's working.
You can see that it has a flame. So, I'm also making it hot. Okay, you mustn't touch any of this with your hands.
You need to have tongs like this. And, all I'm going to do is quite simple. So, I'm just going to hold the butane torch on the crucible, aim at the gold like this and it's just going to heat the gold up.
You don't want to hold a butane torch so it's upside down or at a too low angle because it tends to go out. So, you're just going to have to hold it like this, okay, and you don't know it but the actual crucible is getting very, very hot now. It's getting up to a thousand degrees and won't stay till it will, probably, flash some of the materials on it, start to burn, and I'll be able to splice.
And I basically have to try not to drop it because it's a very hot crucible. If you drop it on the desk, it'll probably burn it. So, I'm just moving the torch around, and trying to get as much heat as possible on to the gold.
Well, I can see the gold is starting to go a bit orange in color. Around the edges, it looks quite shiny and it'll start to look like it's wet on the surface. And this is getting quite orange now.
So, as it gets hotter and hotter, it gets into different temperatures, actually changes color, gives off different lights, gives off orange light when it gets to a high temperature. And it's about to start melting, looks very orange. You see it's molten now, it's wobbling, it's moving.
You see? So, anyway, that was molten enough, and if you get molten enough, when it really gets molten, you can pour it into a mold or something like that, and you can make some type of jewellery with it. So, that's how you melt gold. Quite difficult, but you've got to have a lot of safety equipment, that's the important thing to do. .
