Warning: This set of instructions is intended for intermediate and experienced Minecraft players. If you are not an experienced MInecraft player you will need to follow the in game instructions to learn how to play the game in order to be able to follow these instructions.
This set of instructions is a guide on how to construct a glass dome on Minecraft. A glass dome in Minecraft is a pixelated dome meant to resemble a real-life dome. Since Minecraft is strictly square the dome will not be spherical, but it will resemble a curved, spherical dome as shown in the figure below. This process could take a few minutes to a few hours depending on the size of your dome and how skilled you are at Minecraft.
In order to start building the dome you will need the following materials (Fig. 1 shows an example of these materials):
– You will need a certain amount of glass blocks depending on the size of your dome.
– You will need one 64 piece stack of dirt blocks.
These are the only materials you will need unless you have not yet made glass. If you have not made glass yet, you will need the following materials to make glass (Fig. 2 shows an example of these materials):
– You will need a certain amount of sand blocks depending on the size of your dome.
– You will need coal or charcoal, specifically an eighth of the amount sand you are using.
In order to start building your dome you will need to choose a size for your dome. The chart below shows the blueprint of valid dome sizes in Minecraft that you can choose from. Once you have selected the size of the dome you will need to clear a sufficient space in order to build the dome. This simply requires making a flat surface in your MInecraft world big enough to hold the diameter of your dome. Once you have done that you will need to follow the chart below in order to outline the bottom of your dome with glass.
Note: In order to avoid wasting glass blocks use dirt blocks to outline the dome and when you know that the outline is correct you can replace the dirt blocks with glass blocks.
At this point in the process you will need to either have all the glass needed to make the dome or you will need to continuously make glass by burning sand in a furnace and using coal or charcoal as fuel for the furnace. Now you can start to construct the dome. You will need to reference the chart in the last step for this. You will need to construct a half circle going vertically into the air at the points where the cross in the chart touches the circle on both sides. This will complete the outline of your dome.The figure below shows a small example.
Note: The size of the half circle is half of the size of the dome you choose.
Next what youre going to do is add blocks to the perimeter of your dome. The amount of blocks you add is based on the size dome you have chosen. For a size 39 dome you will add 4 blocks, for a size 21 dome you will add 3 blocks. The figure below gives a visual example. In order for you to figure out the number of blocks you are supposed to place vertically you have to cut the outline of the dome in half and take the number of blocks from where the cross hits the circle to the point where the blocks shift over. Once you know how to do this the rest of the dome should be fairly easy to complete.
After learning the last step all you have to do now is repeat the last step, except you follow the outline and push in one block for each layer of glass and reduce your wall vertically to match the dome outline that you made in step 3 until the dome is completely finished. The figure below shows the best representation of this process because it is very hard to show visually.
Finally your glass dome should be complete and it should look something like the figure below. It may be smaller or larger depending on the size you choose for your dome. I hope these instructions have helped you in the process of making a glass dome on Minecraft. If they have not satified your needs here are a few video links that may help you.

I already knew how to make a dome its just I wasnt sure if I made the main circle correctly. This site was really helpful but it would help more if your step 2 picture went further than 39 blocks. I understand if you dont have time to but I was hoping it would go up to 200. Well I guess 201 since every one of you circles were a negative number of blocks. I know it sounds crazing asking you to make one 201 blocks but its cause Im making a hunger games map so.
Great instructable, thanks for the diagrams
i dont understand this its to confusing
if u r on PE, try MCPE master. It is not availible for apple devices, though. and its free.
Pretty good… Could be better though. Some of it doesnt make sense but once you work it out its easy.
This doesnt make the slightest bit of sense…
I finished several domes and the best way I can describe step four is to just add blocks on the ring you made and follow the arch you made originally. This still probably doesnt make much sense but if you want to ask me and youre on PC log on to for help.
I get that this tutorial is for survival mode, but these things are better done on MC Edit. Within a minute you can create a big dome like the one on the screenshoot! Why all this trouble? 😛
Thanks for the guide! I found this tool for giving a grid layout of circles that you input the size of. Might help those making larger circles
This helpped me so much, after understanding what to do it was easy to make a Giant pokeball. It was perfect thank you
yeah see step four doesnt make the slightest bit of sense and the picture doesnt help.
Wait Nevermind I figured it out haha oops sorry for bothering you
Im sorry but I was a little lost about the part on how to find the number of blocks for height of the dome. Can you please help me how to figure it Im very confused haha
Im sorry but I think you got the picture 3 from samosir on the minecraft forums.
Do you know MCedit? It a very useful tool for Minecrafters that make maps. With it? you could easily generate a dome like this in a few clicks of the mouse instead of actually carrying out the building process.
These instructions are for people on xbox as well as PC, with that being said some people do not have access to MCedit. These instructions are for those less fortunate but thanks for mentioninb MCedit because it is a very good tool for this type of project.
when adding the blocks for hight do you make it like a pyramid?
