Light level[edit source]

The description says it gives off a "soft light," then says "(level 15 light.)" Those two together don't make sense. Level 15 light is sunlight. So the 'soft light' is brighter than torches? I haven't been down to the nether yet, so I can't check which of those contradicting statements is true. Kmach 04:30, 31 October 2010 (UTC)

Could someone confirm if it's really level 15 light? I did some testing of my own and thought it was level 14 instead. - Tanjy3 09.40, 31 October 2010 (UTC)

It does appear to be one level higher than the torch. Levy 10:38, 31 October 2010 (UTC)

Ah right I forgot to count the block itself. -facepalm- My bad. - Tanjy3 11.30, 31 October 2010 (UTC)

Name[edit source]

Why not call this sulphur? Has Notch named it? The dust is sulphur yellow, it looks like brimstone.. --NelsonMinar 13:49, 31 October 2010 (UTC)

Sulphur doesn't glow. Levy 17:19, 31 October 2010 (UTC)

I think it should be called Peanut Brittle. <3 Ibutton77 21:31, 31 October 2010 (UTC)

I actually started calling it a name I came up with using a combination of Illuminate and -ium. Illumidium. Sounds alot cooler than lightstone anyway. >_>

How about illuminum? Illumidium doesn't flow as well.

probably cause it sounds the same as Aluminum.Toadbert
In my opinion, the best name I've seen for it so far is Luminite. With that name, the yellow powder would be Luminite Dust. I think both have a nice cadence to them. BobSalawalatski 08:30, 17 Nov 2010 (UTC)

@Notch Named it "Yellow Dust" in reply to @Jeb_ See Tweet [1] Br4indead 12:55, 13 December 2010 (CST)

Name has been confirmed, 'Glowstone' and 'Glowstone Dust' has been confirmed in Beta 1.0, I've edited most of it, bar the title and possibly some parts I missed. JKGallagher 18.:05, 20 Dec 2010 (UTC)

Does this page really need six alternate names listed, including one that is now the name of something else? JaffaCakeLover 11:49, 21 December 2010 (CST)

Destroying tool[edit source]

"It has been found that Glowstone does not need a tool to be harvested, and when destroyed uses the same sound glass makes when shattered. Using a sword will harvest the material much faster."

Wait, has this actually been tested or is this edit just random? I will test this right now. Levy 01:36, 1 November 2010 (UTC)

Wow, definitely confirmed that, but I am going to reword it for easier comprehension. Levy 20:50, 31 October 2010 (CDT)

If you get a moment could you also just verify that a pick is indeed the "correct" tool to use? That is, it only damages the durability by one point. I imagine the sword is taking two points in the same manner when using it to remove leaves rapidly. --XipXoom 20:53, 31 October 2010 (CDT)

Test- Wood Pickaxe destroyed 33. Test- Wood sword destroyed 17
Conclusion: Pickaxe IS the correct tool, but the sword is faster at breaking it. Levy 02:32, 1 November 2010 (UTC)
Excellent testing. Thank you. :) --XipXoom 02:36, 1 November 2010 (UTC)
Further testing. Test- Wood Spade & Wood Hatchet both destroyed 33. I believe there is no ideal tool. It is a choice between speed collecting the items, or how many items you can collect. In the end, just using your fist would be the best option to harvest Illumidium.

Correct, in the code, Glowstone Blocks in the code as of 1.0(Official Release) are of type "Glass", meaning that they are broken fastest with a Sword, where any type of sword will have the same time, but slower with any other tool, where anything else besides Sword regardless of type will break it for an equal and slower than Sword time. If broken with a Sword, the Sword will take two points of damage. Regardless of what is used to break Glowstone blocks, as of beta 1.8, they drop 2-4 pieces of Glowstone dust.

"Melts ice/snow"[edit source]

This isn't true, unless this is a glitch.

The room is full of ice blocks (4 snowballs). Maybe the ice blocks don't melt?

Not sure how to embed picture, so here's a link.

Snow blocks (NOT ice blocks, that's when water freezes) do not melt. My original map was a snow world so infront of my base is a :giant lake of ice, and placing a "Lightstone" block on it makes a decent area (something like 4 radius) melt. Also tested on a brand :new world in an winter type biome against snow and ice, melts both. --HandOfCode 17:15, 4 November 2010 (UTC)
I believe the passage refers specifically to naturally occurring ice and snow, rather than crafted snow blocks. Is it worth clarifying in the article, considering it links to ice and snow, and doesn't mention snow blocks? --Atr 13:09, 31 May 2011 (UTC)

Does Not Cause Damage to Hostile Mobs[edit source]

I removed the paragraph stating that glowstones cause creepers to explode and skeletons and zombies to burn as per sunlight. I have tested this (SSP Beta 1.2_02) with a zombie standing directly under, beside (both head height and leg height), and on top of glowstones with no effect other than to be very well lit. --KADC 19:47, 7 February 2011 (UTC)

Optimal Way To Mine Glowstone[edit source]

I've found that tunneling through the ceiling and coming at the glowstone form above seems to be the best way of mining large ammounts, although using netherrack (as it is plentiful) to build bridges is faster, it is a lot more dangerous if not playing on peaceful.

Page tampered with[edit source]

Looks like I have to go and fix this page... someone thought it would be a good Idea to put a paragraph between every word...

Glitch found[edit source]

I'd post this on the actual page, but my only proof is recent personal experience so if someone asks me to cite it I won't be able to. I just found a hunk of Glowstone blocks in the Nether that weren't glowing. I don't know if the dust I get from such Glowstone will produce Glowstone blocks that don't glow, and I will be testing that soon. Point is, there's a glitch with Glowstone blocks that happens sometimes. Not sure if that information is valuable, but I'm taking note of it anyway.Wandergirl108 05:30, 12 May 2011 (UTC)

Okay, I just tested the dust and it's fine. I also discovered that if Glowstone blocks aren't glowing, another light source illuminating them will make them glow, which happened when I made a portal right underneath them and then activated and deactivated the portal. But the glitch still happened...Wandergirl108 18:44, 12 May 2011 (UTC)

There is a general lighting bug were sometimes the lighting of a block will not update (often seen where certain blocks remain at nighttime light levels during the day). Putting another block next to it usually updates the lighting. I'm guessing this was the same bug. --Warlock 18:48, 12 May 2011 (UTC)
The thing about that is, when I placed the obsidian blocks right next to the Glowstone blocks, they didn't update; it wasn't until after I activated the portal that the blocks started glowing. I know about that glitch; I've seen it myself. I can't help but feel this is something else...Wandergirl108 03:32, 13 May 2011 (UTC)

I have found a similar glitch with magma in a smith in an NPC village. It doesn't seem to give off any light. --TheMinimoo 17:26, 8 June 2012 (UTC)

Pickaxe[edit source]

As of Beta 1.6.6, you need a pick to mine glowstone. It remains unchanged in SMP, probably to be fixed in the next patch. CactusTrio

It appears to be possible for it to only drop one dust. I was chatting with a friend on his server about the update, and how much dust was dropped. I hacked in a glowstone block, broke it, and only got 1 dust. And yes, the server was 1.6.6. Considering the bugs we'd been having with 1.6.5, my friend updated at the first opportunity! Pi4t 23:36, 4 June 2011 (UTC)

Can't create glowstone?[edit source]

So, I just went in the nether and gathered 22 glowstone dust pieces... and I went back to the overworld, and when I try to craft a glowstone block, it shows the glowstone but when I click on the glowstone I pick it up and half a second later it goes back into the crafting square. I can't make any glowstone. Insanity 22:07, 1 June 2011 (UTC)

(this is on SMP) I tried exiting and coming back in, logging out and back in, going to a different place, using a crafting table, restarting my computer... nothing worked. Insanity 22:12, 1 June 2011 (UTC)

Maybe because the server was running the old version and checking your recipe (2x2) against the old one (3x3)? Aib 00:01, 2 June 2011 (UTC)
The server's been recently updated, and when I try a 3x3 recipe, nothing even shows up, so I don't think that's it.Insanity 00:07, 2 June 2011 (UTC)

The new update says, 2x2, instead of 3x3 now, so try 2x2, like a box made of 4 glowdust

Jeez man no more presure, take it easy,

Araimos 00:12, 2 June 2011 (UTC)Araimos

I know. That's what I've been trying. Insanity 00:20, 2 June 2011 (UTC)

Use the old recipe. It won't appear in the crafting block on the right, but if you click the empty box, you'll get a glowstone block. 3x3 is the old recipe and won't show as giving anything, but it actually still does. CSMoneybags 11:51, 4 June 2011 (UTC)

Requested move of Glowstone [Block] to Glowstone [Disambig][edit source]

I feel that glowstone blocks and glowstone dust are 2 different things, ergo they should stay apart. I do think we should add a small blurb about glowstone dust to glowstone block page. Thoughts? –Preceding unsigned comment was added by EmeraldGem35360 (talkcontribs) at 13:34, 24 October 2011‎ (UTC). Please sign your posts with ~~~~

Glass Block in RC2?[edit source]

I was poking around in some videos (Plants VS Zombies by FVdisco, mainly) and it turns out that the level doesn't work because the wires run on glowstone and glowstone has apparently been changed to glass, testing this ingame, i found that a sword once again mines glowstone, so maybe it should be changed...

Your fist works just as well JohnnyAlpha 14:49, 20 November 2011 (UTC)

Weird...[edit source]

After 1.0.0 now, you can no longer place things like Doors on Glowstone for some reason... Anyone else experiencing this?

Glowstone is now considered glass, so it has the same restrictions glass does. --Saphireking65 04:55, 22 November 2011 (UTC)

Its name in the coding[edit source]

the actual glowstone block class is called BlockGlowStone, not BlockLightGem, this means that nearly everywhere it's referenced in the coding, it's called glowstone. It's true that is "tile.lightgem" but I think it shouldn't say that it's called lightgem in the coding, so I'm going to change it. 18:18, 19 January 2012 (UTC)

Redstone cannot be placed on gowstone as of 1.0.0[edit source]

Since 1.0.0 almost all of my redstone circuits broke, due to the fact that redstone is now being unplacable on glowstone, so I want this to be changed back. ExE Boss 09:35, 24 February 2012 (UTC)

Since snapshot 12w06a, redstone dust can again be placed on glowstone. -- Orthotope 09:44, 24 February 2012 (UTC)

Notch never denied lanterns at Minecon 2011![edit source]

The source given in the Trivia section,!/notch/status/27020001291, doesn't mean Notch implied the asker to go to Hell- he was referring to having to go to the Nether to get Glowstone.

Should we change this? –Preceding unsigned comment was added by SimonT (Talk|Contribs) 03:41, 28 February 2012. Please sign your posts with ~~~~

That was actually the second half of a trivia piece which was incorrectly removed, and gave the tweet proper context. Fixed. -- Orthotope 04:15, 28 February 2012 (UTC)

once per chunk?[edit source]

I think glowstone attempts to form a nodule once per chunk. I've been mining a lot of glowstone recently, so I feel fairly confident about that...just not confident enough to try and put it in the actual article. 03:30, 14 March 2012 (UTC)

Glowstone Solidity[edit source]

The Solidity of glowstone is questionable, as items dropped in the path of a piston pushed glowstone do not get pushed out (as per sand before a recent update.) Similarly, you can see through walls connected to glowstone if glowstone is pushed at head level. Semi-Solid might be a better word for it. Iyeru 12:27, 8 July 2012 (UTC)

Or, y'know, transparent. ディノ千?!? · ☎ Dinoguy1000 13:26, 8 July 2012 (UTC)
Glowstone can't be seen through though. Iyeru 22:47, 8 July 2012 (UTC)
Transparency in Minecraft is not the same as transparency in the real world. It just means that light passes through a block, not that you can actually see through it (you and the block being pushed into each other notwithstanding). Lava, for instance, is transparent, as are slabs and stairs. I would suggest you actually read the Opacity article before trying to tell me I don't know what I'm talking about again. ディノ千?!? · ☎ Dinoguy1000 05:07, 9 July 2012 (UTC)
Translucent better describes the properties of transparent blocks. YetAnotherGuy 05:55, 9 July 2012 (UTC)
Maybe so, but you'd have to talk to Notch/Jeb about that, AFAIK "transparent" is the official terminology. ディノ千?!? · ☎ Dinoguy1000 06:39, 9 July 2012 (UTC)
Transparent means that it takes the colors / etc. of the parent object. This is not the case with Glowstone. Lava does however, as you can see through it while inside it. Water can be seen through physically while standing outside of it. Similarly, Nether Portals, and End Portals (Only from bottom. The end portal is a liquid skin, as the same occurs to water and lava if you take away the overlay and magnification.) Iyeru 17:43, 9 July 2012 (UTC)
As I already explained, transparency in Minecraft only refers to light passing through the block. The visual transparency of e.g. the untextured half of slabs (where you can see through the block space) is unrelated to that, though generally speaking, any block that does not visually take up the entire block space will also be transparent.
Your real-world definition of transparency is also off; a transparent object does not adopt the colors of objects behind it (from the viewer's perspective), it simply allows light, and thus color, to pass through it. CSS transparency does work somewhat like your definition, though. ディノ千?!? · ☎ Dinoguy1000 18:41, 9 July 2012 (UTC)
Opaque / translucent is your definition, where the light/color passes into the current object. Transparent is where you can see through the current object (Real world), hence it takes on the object's properties that are behind it (CSS.) Opaque / Translucent means that raw light can shine through it, yet the object changes said color into other forms of light. (This happens when looking at a nether portal.) Iyeru 10:43, 10 July 2012 (UTC)
Except, as I already explained above, "transparent" is the term used officially for this in reference to Minecraft. ディノ千?!? · ☎ Dinoguy1000 19:23, 10 July 2012 (UTC)

Colored Glowstone[edit source]

Having no Idea where to post this, I will post it here. I believe Glowstone should be dye-able. Just like wool, using the same dye methods as wool. This way you could be more creative with lighting. Also with the Redstone update, could be implements with a lot of games etc for redstone. Such as red, yellow, green lights, etc. Redstone Lamps should also be dye-able. This would be a huge improvement to the games lighting overall and a great addition.

Glowstone Blocks Light[edit source]

You can test this yourself by digging a 1x30x1 hole at daylight. Go inside the hole and the bottom is fully lit. Cover the hole with one block of glowstone, the top would be well lit, but the bottom is dark as if there was no sunlight.

It doesn't let light pass through, it just looks like it lets light pass through because it is a light source. J192 03:10, 20 July 2013 (UTC)
