Glassforged

TTRPG Fictional · Very Rare · Timeless

Produced when molten arcane glass, glass melted from solidified magical energy, is cooled in contact with a ferrous metal under sustained enchantment. The two substances interpenetrate at a molecular level rather than forming a conventional alloy, creating a transparent material with the structural properties of steel.
