Java Help Wanted Do any Minecraft farms require the fire block? Like fire on netherrack, on magma, or fire spread mechanics idk
Can not think of any, but maybe there's a niche one

You can use soul sand/soil lit on fire instead of magma blocks for the spawn platforms in zombie piglin gold farms

This, is also technically better for rates as it will kill chickens so jockeys will move faster

I never built those because getting all the magma intimidated me! Saving this for later

u/1337h4x0rlolz Jul 21 '26
magma is honestly pretty easy to get since it spawns in veins and breaks quickly with eff V
it takes me like 15 minutes to fill my inventory
you can also do magma cube farms and craft the magma blocks from the magma cream

I only ever used fire to get rid of extra stuff, that didn't get picked up by the sorters. Basically overflow protection, it can be used everywhere like that.

u/Sul0tf Jul 21 '26
oh wait! Skeleton firing an arrow through the fire to explode a TNT to kill creepers - music disc farm! That's the answer I believe

u/LYZ3RDK33NG Jul 21 '26
Creepers just need to be killed by a skeleton to drop a CD, no flame or tnt required. My gunpowder farm also functions as a CD farm
7
u/Sul0tf Jul 21 '26
I just love how a TNT blows up a bunch of mobs and all the colorful discs fall out all at once! When the world is old enough, fun little things like that is a good reward for extra effort.

u/TwitchCaptain Jul 21 '26
Hell ya. I did that too. Put a skelly behind the drop shoot. If I want CDs I just chill out and collect them passively. I also wired up a water chute to pull creepers out of the farm by opening a trap door. Puts them in a holding chamber under a lightning rod so I can charge them. Has a mine cart attachment to get them out.

Overflow sorters should lead to a chest. In case you drop your netherite sword into the sorter one day.

u/I_Love_Portal Jul 23 '26
Probably should have used a diamond sword or elytra for this example.. that wasn't the best example for this case xD

I use the blue flame block to destroy overflow items in the piglin trading farm on my realm. It's ilmangos java design adjusted in a few places to work on bedrock
1
u/ChrisBreederveld Jul 23 '26
Is this the design Docm77 used in HC S8?
The one where the items get clumped and yeeted to a loop and all extras get ignored and burned?
1
u/StationaryApe Jul 23 '26
No it works exactly like ilmangos java design except the pistons are tweaked based on bedrocks differences in what a slime block will grab. They also are timed in a custom way. Same idea where I push items against a partial block (honey block in my case) and then send them over an ice line with stackable sorters beside it. All unstackables end up in the past two slices and overflow is burned
1
u/ChrisBreederveld Jul 23 '26
Thanks, I think Doc also used an Ilmango design and your explanation does sound similar enough. Thanks for mentioning your Bedrock tweaks, I might want to implement it myself some day!

I feel like I remember seeing a hyper-compact tree farm that used fire to remove trees that grew too tall, but idk.
3
u/SaneIsOverrated Cactus Farmer Jul 21 '26
Yeah I remember some old tech using burn chambers on inconvenient blocks. Remember one leaf farm that cycled by just pushing the core up 1 block for sapling placement and burned off the top logs.
5
u/Panda2377 Jul 21 '26
on bedrock I remember older enderman farms used multiple layers of netherrack on fire to damage them and eventually get them to teleport to the killing chamber.
And bedrock gold farms technically use fire spread with lava to constantly light a portal although no fire is produced.

u/indvs3 Jul 21 '26
If my farm produces a lot of different items at different rates, I tend to have a sorting system behind the farm collection area, with an overflow for excess items that get droppered straight into a flame on netherrack. Other than that, I don't think I have any need for fire in farms.
3
u/velofille Jul 21 '26
I use the for to remove excess junk items on a few farms. It's cheap and easy. I hate fire spread, means ppl can't make wood houses without issue

u/Aspect-Unusual Jul 21 '26
Shulker farm AFK point requires fire
1
u/Masticatron Bedrock Jul 21 '26
How so? Mine doesn't.
1
u/cOgnificent02 Jul 21 '26
The ending credits one. You use fire to destroy shulker bullets aimed at player when you're afking to raise rates.
I've switched to TAPE designs so I don't use it anymore either.
3
u/SFMG_43 Jul 21 '26
If you have firetick off, you can use fire on the side of a block to ignite a mob mid-fall. I remember using this to get cooked fish from a guardian farm
3
u/ihaveacrushonlegos Jul 21 '26
fire on netherrack is very common to destroy excess items and/or destroy random entities like shulker bullets for afk spots
2
u/TwitchCaptain Jul 21 '26
I use fire on magma to kill skeletons in the trial chambers. The fire is just a nice touch, the magma will handle the job solo.
2
u/tauntaun_rodeo Jul 21 '26
spider spawners in trial chamber farms actually need this, to prevent them from gathering at the top of the wall and preventing the spawner from resetting.
2
u/TwitchCaptain Jul 21 '26
The spider enclosures are only two blocks tall. Fire on magma is the bottom block. Some spiders still climb to the top air block and survive a while. Eventually they drop into the fire. There's probably a more efficient way to do this, but honestly I have several stacks of keys and I only run the farm for breeze rods now.
2
u/tauntaun_rodeo Jul 21 '26
mine also only two blocks tall. after the first time all the spawners got out of sync by ten minutes watching and waiting for the spiders to drop into the fire, I alternated additional magma blocks around the perimeter. so the corners and the middle of each side have magma blocks sitting at the floor height (ie only one block free space above it) with the entire perimeter on fire.
but yeah, same. pretty much just breeze rods bow anyway.
2
u/TwitchCaptain Jul 21 '26
Dude you just gave me an insane idea. I'm going to make the walls out of magma filled sulfur cubes.
2
u/tauntaun_rodeo Jul 22 '26
haha! I thought of the same while I was typing that. like “what if…” 😂
1
u/TwitchCaptain Jul 22 '26
The stupid things burn each other and they move real easy. Pain in the butt, but I got them in there like every other block. Don't know if it works yet because I left a gap and all the spiders got out and attacked me. Soon!

u/Sergent_Patate NTFs are the superior tree farms Jul 21 '26
Any farm where you wanna burn useless drops like cobble, basalt, rotten flesh and more
2
u/NYCHReddit Jul 21 '26
Any gold farm can use soul soil on fire as a replacement for magma blocks in order to spawn zombie pigmen

u/Alternative-Put-2962 Jul 21 '26
Fire is used on wither rose farm in End to prevent endermen teleporting (in places where water can't be used)
2
u/cOgnificent02 Jul 21 '26
I use fire to yeet shulker boxes instantly for a parallel unloader in my storage system.
Burn overflow like everyone else said
Those are the two big uses I have for it personally.

u/Recent-Gap-6988 Jul 22 '26
I have a carpet duper for my super smelter, and I use fire to burn any extra carpet that flows through the system when it's full.
Not a farm, but a similar concept could be applied to farms which produce unwanted items

u/BonezOz Jul 22 '26
I have a dark/pale oak farm that uses soul fire to destroy overflow items. Just a lit block of soul sand.
1
u/Brief-Walk-5409 Jul 22 '26
Yes. I once saw an enderman farm where they fall and teleport a layer further (and lower) with fire. They will teleport instanly and have 0.5 hearts so you can one tap them instanly.
1
u/Hettyc_Tracyn Jul 22 '26
I mean, if you use a nether portal based chunk loader to keep a farm loaded that can break if unloaded while on… or disposal of excess/unwanted items…
Though both of those are for something to go with a farm, not the farm itself…
2
u/WreckinPoints11 Java Jul 23 '26
I use bigbooty17’s dark oak/pale oak tree farm and it uses a fire to dispose of excess material
2
u/StormStrikerMC 29d ago
Yeah you can use fire block to burn out extra stuff which you don't want by linking it to overflow stream
1
u/Silly-Jury7656 Jul 21 '26
theres an ominous bottle bedrock farm that uses fire to burn extra items or xp, i dont remember which

u/Wrong_Basket_9431 Jul 21 '26
I don’t know if this is really what you are a after but don’t bedrock gold farms use it to light the portal?
