Salt Furnace

Before dawn the furnace mouth glows tangerine, and the men who feed it move like herons through the cinder light, deliberate and thin.

Salt crusts the iron doors in white medallions. Someone's grandfather built this kiln from river stone and a stubbornness that outlived him by decades.

Now the heat bends air into a second language, one the body learns before the mind — how to turn toward flame without flinching, how to read the color of a pour the way a surgeon reads a pulse.

Outside, the yard holds its breath in frost. A dog circles a patch of gravel, settles where the warmth bleeds through the wall. The shift whistle is still an hour away.

By afternoon the ingots will cool into something ordinary, stackable, sold. But for now they are still molten, still belonging to no one, bright as the first dangerous idea.
