It may be possible to close minecraft while still viewing your death message, open the world in an external editor, and set the world to non-hardcore mode. I am unsure if this would work though.
Level 11 is probably the best overall. If you cannot get coordinates to work on your computer, your feet should occupy the block above most lava lakes. This way, you can simply use a water bucket to cross them (by making obsidian) rather than having to change heights to pass them (or have them pour in on your head)
Lava, I feel, is one of the most under-appreciated resources in the game. It is quite useful in many places. In order to help more people make the most of this liquid, I have put together a short list of its many uses. Things will be added as people post them.
1. Cheap (free), long lasting furnace fuel
2. Powerful lightsource
3. Can be used to easily and freely reclaim land from the sea (as smoothstone)
4. Can be used defensively (as walls and moats)
5. Can be used in a grinder
6. (Cobble)stone generators
7. Construction
8. Incinerator/Trash cans

2. Torches (and supplies to make torches); carry however much you expect to use
3. Cobblestone; it's useful for both building travel bases (to wait out nights) and for tools
4. Food. Because you need to eat things
5. Armor; better not to die and have to find your stuff again, right? Small investment, large payout.
With your tools you can resupply on wood and cobblestone (and as a result, tools and torches)

Alternative uses, not normal ones.
Again, alternative uses.

Anyone else have alternative uses for lava?
