Gloves would do nothing against heat, unless they're fire imp leather or fire spewing FB silk and the like, as ordinary stuff should catch fire at those temperatures. The explanation I've seen is that hauled stuff aren't actually carried in the hands, but teleported into the (obviously heat proof) inventory of the hauler, and thus doesn't touch the hands.
I don't remember if the "I'll steal stuff made from materials I like" bug in 0.42.05 was introduced in .05 or earlier. In the latter case caressing that nice hot mine cart might be harmful...

That bug was present at least as early as 0.42.04. And yes, I did see a dwarf with a preference for iron kill himself by claiming ownership and carrying two iron minecarts full of magma.

I'm also one to go with the path of cart the magma up!  However, the material choices, while respectable, aren't exactly in my eyes an ideal.  If possible, I've gone the route of Nickel minecarts (which are also magma safe) as opposed to iron or steel.  (Aye, I be a bit finicky with my metal usage, even if I have a hundred boulders worth of iron ore.)

I also know that feeling with magma pump stacks mangling the framerate, and to say the least, I couldn't really utilize it for an obsidian maker.

Never did make the Magma Piston work out though...  it's food for thought if I make another fort without volcano.  Though the bloodhand mishap is a new one to me.

[NW_Kohaku]

It takes slightly more work, but it's entirely possible to make an automated minecart conveyor belt, and I made one in my last fort.  I screwed up a bit, so it took about 2 years to build, but if I knew what I knew by the end as when I started, it would have likely been a 1-year project for a 30-dwarf fort.

Let me upload some pictures...

Spoiler: big pictures (click to show/hide)

This is the top of the track.  Ignore the water, that's for something else. The cart goes up the ramp from the right, hits the track stop, dumps magma north, then falls down a chute back to the magma loading trench.  A hatch is placed a floor below that can be shut to stop and start magma pool filling by blocking the cart on its return fall.  There is a 5x7x2 pool of magma below the hole, and to prevent overflow, that pressure plate will trigger the shutoff hatch.


This is my magma and separate water disposal system. (ALWAYS BUILD LIQUID DISPOSAL SYSTEMS FIRST!) Do not open both at once. Water flowing to the edge makes all water connected into a "river" that counts for making all water "moving" for waterwheel purposes, even after access to the edge is removed, removing the need for FPS-draining pumps for large water wheel operations. Those are fortifications liquids can flow through on the South edge of the map.

The cart falls down a 108-z-level shaft to...

This track. Ramps send the cart to a ditch filled with magma. The wall prevents skipping. Upon being loaded with magma, it is pushed up a ramp, given a boost with "impulse ramps" and pushed up a spiraling impulse elevator as seen in the wiki.


In this trench is a straightaway (with ramps, obviously) with rollers of magma-safe materials set to the lowest setting, because the cart must move slowly to fill with magma, and a cart on a roller is immune to rolling back down the hill.  The rollers receive power from the magma-safe pump pumping from an iron grate over the magma sea.  A separate water wheel and pump with water taken from an aquifer down a 114-z channel provide power. The bridge in the bottom-left is an atom smasher for draining the water, while to the right of the magma trench is an atom-smasher for draining the magma trench.


This is my impulse elevator, running on impulse ramps.  Without ramps, tracks look like this:

░▼▼░I don't recommend copying my exact design. It turns out, after making it, I would have been better served with a 4x4 impulse elevator (for the fastest, no-collision carts) or a 2x2 impulse elevator (for the least digging). As this stands, the cart has collisions and goes up slowly, although predictably enough IF there is no following cart close enough to it.  A 4x4 elevator does not have this problem, and can send a cart directly uphill.

To the immediate left of the impulse elevator is the cart return shaft, 108-zs of channeling.  I had to make a few exits into the impulse elevator, as miners would need breaks while channeling themselves down, roughly every 5zs. It's probably better just to have a up/down stair along the shaft, I don't think the carts will ever fly sideways.

Up and to the left, is another channel and up/down stair, this one for allowing water from the aquifer down to the waterwheel chamber that powers the rollers and magma pump.

I give credit to Expwnent for teaching me nearly everything I know about minecarts.  I also know that Expwnent also made a system, for those with iron to spare, that can use more than one minecart with collisions to force carts in the magma trench out, (so no need for rollers) and keep magma flowing up at near-pump-stack speeds, requires no manual effort, and is the easiest method on your FPS, as carts are fairly insignificant for FPS.

Note that this design can also be expanded - I eventually carted magma up to obsidianize a river so I could work on the riverbed before channeling it away.  (Stocked underground fishing lake with no outside access, YAY!)

[PatrikLundell]

It's fairly rare to actually need the full capacity of a magma pump stack, so NW_Kohaku's mine cart based method is usually sufficient for most magma needs in terms of capacity.
The reason I usually stick to carried mine cart is that each cart goes to a different location, such as one tile along the edge of a cavern above a cavern lake to secure that lake (the alternative is to use pump stacks and retracting drawbridges, which I do if there's a lot of water to secure, provided, of course, I've got the building materials [I'm usually embarking in metal free embarks, so glass, nether-cap, candy, and goblinite tend to be my source materials, and only candy is {supposedly} guaranteed]).

[NW_Kohaku]

I, personally, really like glass, so I only accept embarks on sand.

There's also nothing stopping you from impulse ramping your magma up the majority of the way, then setting up track stops and having dwarves carry the magma a shorter distance, although I personally might just carry magma up to a massive reservoir and then set up systems to funnel it out to other projects.  Also, my embark had no iron, so I did that track using only, I believe, 6 or so iron, although that track is only using two carts. 

Expwnent, meanwhile, set up a much more efficient system with no wall collisions that could drop 2/7 magma every 11 ticks, I believe, which rivals a pump stack in speed (if only because draining magma from the magma sea eventually results in the bottom pump not being able to reach more magma until the magma sea refills) without the massive cost in resources or the FPS death.

Also, protip: USE MACROS. Each floor of a 4x4 elevator will take about 20 keypresses, and you'll be going up over 100z levels, so you're going to get bored silly doing it manual.  To keep the macro short, try doing only every fourth floor at a time in a macro, then going back to the bottom, and trying again from there.
