The note presents a startlingly immediate, sharp, and intensely acrid impression, reminiscent of the instant a wooden match head ignites. It possesses a distinct metallic tang combined with a brief, volatile burst of burnt gunpowder and the characteristic pungency of elemental sulphur. Initially sharp and almost aggressively dry, it projects with surprising force for its ephemeral nature, quickly dissipating to leave a ghost of smoky wood and a lingering, slightly gaseous warmth. It functions almost exclusively as a top note, a fleeting dramatic opening statement, rarely persisting beyond a few moments, yet its impact is profound and memorable. There's an underlying friction, a scratchy texture almost perceivable, before it gives way to other notes.
