The Cauldron of Blood is a Daemon Engine used by the forces of Chaos that is completely dedicated to the service of the Chaos God of war and bloodshed, Khorne.
The veins of Daemons flow not with mortal blood but the red-hot lava of Daemon blood. A huge, bubbling cauldron of Daemon blood is carried on top of the Daemon Engine to supply the great cannon which juts out of its front. Once targets are within range a great gout of blood is fired through the projecting nozzle, raining the foe with molten lava.
This profane liquid flows over and around cover, and can reduce whole buildings to rubble. Like all Daemon Engines of Khorne, the Cauldron of Blood also carries massive combat blades on its prow to slice through the opposition. Warhammer 40k Fandom

The “Khorne Cauldron of Blood” is one of the more obscure and visually striking Chaos war machines produced by Games Workshop during the late 1980s and early 1990s for the original Epic scale and early Warhammer 40,000 Chaos ranges. It belongs to the wider family of Khorne daemon engines that emerged during the formative expansion of Chaos lore in the late Rogue Trader era. The miniature first appeared in the era when Games Workshop and Citadel Miniatures were rapidly developing the visual identity of Chaos. During this period, Chaos was transformed from a relatively generic fantasy evil force into a highly developed mythology centred on the four Chaos Gods: Khorne, Nurgle, Tzeentch, and Slaanesh. The publication of Realm of Chaos: Slaves to Darkness was especially important in establishing Khorne’s imagery of brass, skulls, blood sacrifice, chain axes, and daemon infused machinery.

The Cauldron of Blood itself was not originally a mainstream plastic kit in the modern sense. It appeared as a specialist Chaos daemon engine in Epic scale and later in larger resin or metal forms associated with specialist Chaos collections and Armorcast era super heavy models.

According to later lore compilations, the engine carried boiling daemon ichor which functioned as ammunition for a grotesque cannon that projected molten blood across the battlefield. The miniature is significant historically because it represents a transitional period in Warhammer design. During the late 1980s and early 1990s, Chaos vehicles were wildly experimental and often surreal. Before the cleaner visual consistency of later Warhammer 40,000 editions, Chaos machines resembled medieval torture devices fused with industrial machinery and daemonic possession.

Many collectors regard these early daemon engines as some of the purest expressions of old school Chaos design.
Unlike modern Warhammer kits, the Cauldron of Blood was never a central mass market release. As a result, original miniatures are comparatively rare and now mainly circulate through collector markets and specialist oldhammer communities. Surviving examples are usually metal Epic miniatures or resin Armorcast variants. The model also reflects how Chaos evolved across both Warhammer Fantasy Battle and Warhammer 40,000. Early Chaos ranges often blurred fantasy and science fiction aesthetics, so daemon engines could appear equally appropriate in either universe before the settings became more visually separated in later decades.

Among long time Khorne enthusiasts, like myself, it is remembered less for competitive gameplay and more for its outrageous design and the creativity of early Chaos miniature development.

This version was printed for me by Rob D for my birthday and he has done an outrageously good job and the 3D design and printing.

I will suitably adorn it with an appropriate number of Bloodletter attendees – eight of course!
Thanks Rob for the prezzie and excellent work!
