This is a paragraph cut from the Nocker Kith Book posted by Chris Howard in The Changeling Forum on White Wolf, its not official errata, but its cool.

Balefire runs hotter than most normal faerie flames (though certain legendary volcanoes, dragon breath, etc. may be just as hot or even hotter). For certain nockers, Balefire's chaotic, creative nature renders it as an unparalleled tool for creating Treasures that would be impossible using lesser chimerical flames. Its raw dream energies make it particularly useful for melting materials that might otherwise resist more mundane forging methods. Under certain circumstances even Autumn materials, if properly enchanted can be melted using Balefire which can distill their Dream aspects from the banal dross of the waking world. Certain enterprising nockers have attempted to use this process to bring modern materials such as advanced ceramic composites, plastics and metal alloys into the Dreaming. While occasionally successful, this process is a long and arduous process fraught with difficulty. While not usually dangerous, it typically entails more frustration than most nockers care to contend with (especially when there are equally useful materials distributed throughout the Dreaming).

System:
All Forged items made with Balefire are at +2 difficulty because of the fire�s chaotic nature, but items so forged thereafter gain an additional point with which to resist Banality. At the Storyteller�s discretion Balefire forged blades also maintain a much keener edge and Balefire armor is simply stronger than its more mundane counterparts. Depending on the skill of the crafter, weapons or armor made with this process receive additional dice to damage or defend. All the most truly extraordinary Forged Treasures in fae history were created with Balefire.
