The solvent evaporates first, leaving finely divided solid particles which move to the hottest region of the flame where gaseous atoms and ions are produced.

(Do not use steel wool, which leaves tiny particles that become embedded in the film.)

It is also better to beat the icing in a china, glass or metal bowl rather than plastic which can leave tiny particles in the mixture.

Dead cells disintegrate but are not completely digested, leaving granular particles.
