Black Iron Oxide Powder - Magnetite - Fe3O4

Premium Black Iron Oxide Pigment (Magnetite) – Intense, Velvety Jet Black That Never Fades

Unlock true depth and drama with high-purity Black Iron Oxide (Fe₃O₄, magnetite) – the ultimate synthetic inorganic pigment for achieving rich, opaque, midnight-black shades with a subtle metallic sheen and unbeatable permanence.

This ultra-fine powder delivers profound jet-black intensity, exceptional lightfastness, heat stability, alkali resistance, and chemical inertness — it stands up to UV exposure, weathering, acids, bases, and solvents without fading, chalking, or degrading over decades.

Perfect For:

• Concrete, pavers, mortar, cement & precast — Create deep charcoal, slate, onyx, or true black finishes in driveways, countertops, tiles, blocks, and architectural elements (ideal with white cement for maximum blackness)
• Paints & coatings (industrial, acrylic, oil, epoxy, masonry) — Professional-grade matte or satin blacks for exteriors, metal primers, artist paints, or high-durability finishes
• Soap, cosmetics & bath bombs — Cosmetic-grade compliant, luxurious deep black for dramatic swirls, goth-inspired bars, eyeshadows, or mineral makeup bases
• Art, crafts & DIY — Stunning in resin jewelry, polymer clay, candle wax, watercolors (for rich shadows), pottery glazes, wood staining, and textured effects
• Plaster, lime render & decorative finishes — Effortless modern-minimalist or industrial chic looks in Venetian plaster, microcement, or rustic surfaces

Highly tinting, strongly opaque, and disperses easily — a small amount packs massive color impact for consistent, streak-free results. Non-toxic when used as intended, eco-friendly synthetic alternative to carbon black (no migration or staining issues in many applications).
