Dare you see a soul at the "White Heat"?

Dare you see a Soul at the White Heat?
Then crouch within the door -
Red - is the Fire's common tint -
But when the vivid Ore
Has vanquished Flame's conditions,
It quivers from the Forge
Without a color, but the light
Of unannointed Blaze.
Least Village has it's Blacksmith
Whose Anvil's even ring
Stands symbol for the finer Forge
That soundless tugs - within -
Refining these impatient Ores
With Hammer, and with Blaze
Until the Designated Light
Repudiate the Forge -
