Glenn's Gases - underground gas, smoke, steam and more!

If you've ever read about mines, you'll know that one of the most dangerous things about mining back in the day were gases. Gases that could suffocate you or explode on the slightest spark. But mining in Minecraft never had this sort of danger… Until modder Glenn put it in. Let's take a careful look.

The mod adds several kinds of gas. There's two types of underground gas, two types on Nether gas, smoke, steam and void gas. Each has unique properties and is dangerous in its own way. We'll take a look at them, also featuring gas pockets and lanterns. Here's the menu:

Green gas

This seems to be the most common gas underground. This green gas will float up as high as it can go (likely to the top of the cave), and stay there. It is highly flammable and will catch on fire if it comes into contact with a torch.

Red gas

Another underground gas, this one is arguably dangerous. It won't float up, but will actually fall down to the bottom of the cavern. When lit with a torch, it will explode. More gas means more of it explodes at the same time. The faster the change, the more violent reaction.


Smoke is created when a block burns up completely (it is separate from the particle effect smoke in vanilla). It can choke you and does damage. It might cause problems during forest fires or if you have a fireplace without a chimney. BUT, if you have a fireplace WITH a chimney, it will look freaking awesome now.


Steam works like you'd think steam works. It's created when you extinguish lava with water, aka. when obsidian is created, so be careful when farming obsidian in small spaces. It'll float up like most gases, so it may catch you on the way up. It does more damage per second than smoke.

Nether gases

There are two nether gases: corrosive and electric. They're both static and form in clouds in the Nether. They deal huge amounts of damage to the player. Electric Nether gas has a great lightning particle effect on it. I'd suggest avoiding them, but hey, some people like to live on the edge. Those people will end up electrocuted and lose all their diamonds.

Gas pockets

Gas pockets are small underground rooms that generate along with the world. Like you assumed, they're filled with gas. You'll come up on them when mining, especially if you like to tunnel a lot. When you happen upon a gas pocket, extinguish any nearby torches and replace them with lanterns or it might blow up in your face (literally).


Lanterns are your weapon against the raging gas tide. Crafted by placing an iron bar over a glass block, they can be placed and a torch put in them. This torch then will not ignite gas, but it will produce less light.

Lastly, there's void gas. A very nice surprise I won't spoil. Right now the mod just makes the game harder and the whole gas mechanic has no further purpose, but an update is coming out soon that will add gas manipulation machinery that will let you use gas as a fuel. It should make the mod even better.
