TNT can be lit by fire. TNT on fire

TNT ignited by fire TNT ignited by fire

Lightning striking on the ground at Medium difficulties and up causes short-lived fires which may be able to trigger an explosions. I haven't been able to test whether lightning directly striking a TNT on Easy or Peaceful will still trigger the explosion.

Lava also causes TNT to ignite as the TNT catches fire because of the Lava. So does lightning if it strikes your TNT, it also causes the TNT to catch fire and it will eventually ignite.

TNT can also be ignited by a Redstone Pulse send out by a Redstone Torch, Button, Lever, Pressure Plate or Detector Rail. This is also the most common and safest method as it doesn't accidentally burn any flammable materials near you. TNT ignited by Redstone pulse

TNT can also be lit by left clicking it while holding flint-and-steel. In creative mode you must use right-click, otherwise the block is destroyed.

Another source of TNT triggering is explosions. TNT can trigger more TNT, as well as creepers, ghasts or exploding beds in the nether.

Very prompt but i am certain there are more ways. – ProSay Sep 7 '11 at 12:02
I don't think there are more ways. I can only think of fire, redstone and creepers... Maybe lightning? – Exa Sep 7 '11 at 14:01
What about switches, buttons, pressure plates, etc...? – BlueSixty Sep 7 '11 at 15:37
they are considered redstone pulse – ProSay Sep 7 '11 at 15:45
Simon of the Yogscast detonates TNT by placing a stone button on the TNT block itself, hitting it and running for safety. However, that's essentially still the same thing as a redstone pulse. – Joe Dovahkiin Sep 7 '11 at 15:57

Yes, creepers can ignite TNT. When a creeper explodes within range, the TNT will detonate instantly.

Any evidence? and you only answered 1 part of my question – ProSay Sep 7 '11 at 12:14
Recorded just for you: The other guy answered the rest of your question, so a bit pointless rehashing, don't you think? – rob2uk Sep 7 '11 at 12:38
The goal is to have one answer that can be marked as accepted, and when the truth is spread out over two different answers because neither of the answerers wanted to "rehash" or just decided to answer part of the question, that's not a good thing. – a cat Sep 7 '11 at 13:13
ok i cant select 2 answer as correct.... – ProSay Sep 7 '11 at 13:15

TNT or creeper explosions will trigger TNT. I'll bet every nickel I have that Bed, Ghast, and Blaze explosions do it also, but can't test that easily right now.

If you set fire to TNT or if fire spreads to TNT it will trigger it. This means lava can ignite TNT..though remember the TNT needs to have one of its six sides free so that the fire can spread to it; a TNT block entirely submerged in lava or surrounded by blocks will not ignite.

If you are holding flint and steel and you punch (left click) TNT it will ignite. This is the cheapest way to ignite TNT because it will not diminish the flint and steel's durability.

Redstone current will trigger TNT. The easiest way to use this is to make a lever (one cobble block, one stick, easily craftable without a table) and set it off using that.

I've tested all the above, and you can do so too easily by popping into creative mode or a test world.

The ways are powering it with red-stone lighting it with flint and steel or putting it near a fire source like lava.

Acctually Lava in itself does not trigger TNT. I have tried placing only lava and TNT but am unable to trigger an explosive even if as said above you have sides free close to lava. BUT! if you place wood or other burnable item next to the TNT that item can catch fire and the explosion is triggered.

Incorrect, I have been able to ignite TNT with nothing more than lava, though it does take quite a while to catch light. – fredley Apr 17 '12 at 9:23

Lava can trigger TNT, it just takes a couple of minutes to ignite it.

Another way is to make a 3 by 3 by 3 glass donut, cut out the corners, then put TNT one-block-high around it. In 30 seconds it will blow up.
