New descriptions for the metals.. again this time with help of vulnus
Scintillack
Mass: 5 kg/liter
This alloy is infused with an odd form of lichen that permeates light. From research this lichen is similar to the Earth lichen that glows in the dark, though this lichen produces light constantly and is much brighter. The metal becomes infused with this lichen under extreme pressure due to the odd properties of the metal.
Thus far the only material the metal has this type of reaction with is the lichen that's used to produced this type of alloy. The producers of it are currently unaware if there are other materials it will react in this way to, but so far all experiments have failed.
So far this glows brighter then most light producing implements.
Nevercold Brass
Mass: 10 kg/liter
This metal produces heat due to it's natural reaction to background radiation. The metal naturally responds to background radiation by producing heat. The metal is also more conductive then copper by approximately ten times.
These metals are unobtainable by anyone apart from golems to to their knack for changing metals
