Im just wondering if anyone out there has information about the ore Alum and how to obtain it. Ive been looking for it for quite a while now on a multiplayer server. Through prospecting I have identified a large number of chunks that contain a "minuscule amount of Alum" and I strip mined through the sedimentary layer of rocks in these chunks but have found nothing. I have even tried going into single player and using a combination of prospecting and worldedit to quickly clear large areas of stone in search for the ores within. I couldnt find Alum even then. So I guess my main question is: How can I find alum? A secondary question might be: Was alum ore generation changed at all in 1.16.x? Perhaps it is bugged? Third: Does prospecting for Alum ever return larger probabilities than "minuscule"? Id like to know more about the ore as well if anyone knows any details on it as that may help in figuring out where to find it. All I currently know is the host rocks that it can be found in (sedimentary) and that it sort of spawns in vertical cylinders. Also, it doesnt seem like anything has really been posted about alum online, so maybe this can help other people as well. Any help would be appreciated!
