The note of hot iron is an ethereal, yet profoundly evocative olfactory experience. It doesn't smell like metal itself, but rather the *effect* of heat on fabric, imbued with a crisp, slightly aldehydic freshness. It possesses a clean, sharp, and almost sterile quality, often described as ozonic or 'air after a storm,' but with an underlying dry warmth. There's a subtle, almost electric hum to it, a ghost of steam and freshly pressed linen. Its texture is smooth, dry, and airy, with a cool initial impression that quickly gives way to a lingering, comforting warmth. Intensity is typically moderate, designed to be distinct but not overpowering. It projects with a subtle diffusion, carrying the scent of order and cleanliness. Longevity is surprisingly good for such a fresh accord, often settling into a clean musk base. It usually manifests as a top or heart note, offering an immediate lift and a sense of impeccable readiness.
