In fact, I'd say that the natural question is, "Does it feel cold when I touch it?" In which case anything below 300 K will be "cold" and anything above 320 K will be "hot," more or less. The coldness of iron really comes from its high thermal conductivity. . . . Bill Stoddard |

Anyway, I don't think anybody before TL5 ever saw any molten iron either, you really can't obtain temperatures high enough to melt it outside a closed furnace. Well OK, I suppose some Chinese blast furnaces may be technically TL4, and it's not impossible somebody had a mica window or something, but....

By your own argument, it seems unlikely that most people would have encountered iron above the Curie transition temperature. So they wouldn't be likely to have a concept of hot=nonmagnetic iron. There's just iron, and iron is drawn to the lodestone. Bill Stoddard |

In real world terms, I tend to agree with you 'Cold iron' is usually just a poetic description, and not a particular kind of iron/steel. |

Re: [LT] Iron and Steel Armor
I still like the explanation from this one book (can't remember title) that the cold part of cold iron was actually a translation error of north
so 'north iron' was iron that pointed north (lodestone) |

Re: [LT] Iron and Steel Armor
? It's not like mountain tops are made of iron. The issue isn't "iron" or "cold", but "cold iron" after all :) Mountain-tops, sub-arctic, arctic, and deserts (at night) will make iron weapons and armor hazardous, but even then a fae beastie could handle an iron item briefly by dumping it in hot water to warm it up

That's waht I was thinking of with my 10C/0C definitions (10C for "cold to the touch", 0C for the "risk of frozen fingertips" coldness) I mean, if you can get your tongue stuck to it, it's definitely cold enough to count as "cold" IMO - I think you can do that at 0C or possibly just a smidge under 0C but close enough for GURPS. But it's certainly "cool" to the touch at higher temperatures (although I'd quibble significantly with your 300K benchmark, and pick something lower than that.

Re: [LT] Iron and Steel Armor
Then there's my interpretation that 'cold iron' is bog iron, especially since bog iron needs less smelting (so the iron is cold while in the bog, and doesn't need to be heated before being worked). Considering that bog iron was an interesting source of iron in Northern Europe, it makes a certain mythic sense that it interacts with the Sidhe and the Elfreich differently than smelted or pig iron.

Re: [LT] Iron and Steel Armor
I am the all powerful thread necromancer!
A friend is running a game where the tech level is a little Janky. It's tech level 4+1, essentially. In high tech, it says that steel doubles the DR for armor at Low-Tech's weight or keeps LT's DR at 50% less cost and weight. Does that mean that Heavy Plate machined to specifications on with TL5 Steel really has DR 18? Or do we follow TL4 advice and add a single point of DR? I couldn't find the answer wilst searching this thread or others.
