I am not saying I invented something new in the world of Minecraft, but it is a personal discovery. Gravel is gold when wanting to stop and kill lava. I started out trying to stop the lava with cobblestone, and it works to some degree, except when it does not. You can not be sure you got all the lava killed, and you might find more underneath the placed cobblestone if you dig it up.
Gravel however, sinks down to the bottom of the pool, and if you keep dropping gravel down you will eventually make a very safe wall and know that there is no lingering lava at the bottom of it.
Killing a whole source of lava is time consuming, deadly, but worth it. This pool will find its end by my hands! My garden depends on it!
I used to loath gravel. Yes, it gives flint, ( I never used it my self, ever.) and sometimes it can be used for decorating needs, but other than that it just takes up space in inventory. Not to mention falling on top of ones head while trying to mine.
I am sure that we could use sand for the same purpose of killing lava, but sand has many other uses, and can be turned into glass and beautiful stone.
This newfound love for gravel have me hunting for it, and when you want it it is rather hard to find. My octopies loves the fact that im making their pool deeper, excevating all the sand and gravel I can find.
And with this I hope I wont have to die in lava, and keep my items! I lost too many things already.
Prosper mining to you all!
