Thaldimine is a bright reddish orange metal that can be found in ore veins deep underground. It requires heat to form and is noted for its fire resistant nature. Even under extreme heat such as dragon fire, the metal doesn't melt and returns to a normal temperature rapidly. The metal doesn't rust or oxidize, so it retains its bright color.

If you're scouting for thaldimine, you'll want to bring a lava stone. Thaldimine only appears in hotspots deep underground, and that stone will let you know when you're in a hot spot. But it can't be too hot or else the ore won't form or it'll be too brittle to use. It's finicky like that for all the trouble we go through to find it.

Usage & Distribution


Due to its fire resistant nature, thaldimine ore must be cold processed. It's an unusual technique where the rocks are cleaned to remove as much waste as possible before soaking them into an ice bath. Ice crystal powder is added to the water to bring the temperature down even lower which melts the ore. The heavy metal sinks to the bottom of the basin into metal molds to form the ingots. The remaining rock is scooped from the tub, and then the water is drained out. As the metal returns to room temperature, it hardens into a solid once again.

Common Uses

Most non-dwarves who buy thaldimine goods want armor or weapons. They pay good money for it, though. The dwarves, they're smarter. Ovens, cauldrons, forges, anything that's going to be subjected to high heat. If you want quality, then you get thaldimine. It'l last your lifetime, your kids' lifetimes, and your grandkids' lifetimes. Probably longer if they take good care of it. And unless you plan on living inside your oven constantly, you're not at risk for overexposure.

I'm quite old enough to remember thalidomide...

This is a brilliant article, and I love the concept of heat resistance while still being able to craft armor from it. Well done!

The idea with the heat resistance is great and how the material can be used. I also like the layout. It has a good overview.
