Cast-Iron Cauldron Censer.

A coal glowing under a pinch of resin, and a thread of smoke rising from the altar shelf. This palm-sized cauldron is sand-cast in solid iron, roughly eight centimeters across, standing on three stubby legs with a small looped handle and a fitted lid. At 400 to 500 grams it has real heft for its size: small enough for a crowded shelf, solid enough to hold a burning charcoal disc and a scatter of resin without warping.

The three-legged cauldron is one of the oldest images of Western ritual: the witch's pot of folk tale, the alchemist's vessel where base matter was worked toward gold, the household hearth made small enough to carry. In folklore it is a place of transformation, where separate things meet over heat and become something else entirely.

How to use

Line the base with sand or salt before you light charcoal inside: iron conducts heat quickly, and the layer protects both the metal and the surface beneath. Wipe it dry after each use to keep rust away.

An old vessel of change, small enough for your own shelf.
