Chimes instantly come to mind

Different kinds of chimes, glass, clay, aluminium

Dust or scattering confetti layers

Clockwork/windup mechanisms/toys

Sparklers, fizzles

Poofs, darker poofs, not comical cartoon ones

Puffs, like powder puff

A musical element, like harp, glock, belltree, tubular bells.. bowed glass works too, as you mentioned, depends on how scary you want to go ;)

+1 for chimes. Other thing that comes to mind are the kinda flash pop things like an old style camera flash burst. The powder igniting for the flashes or whatever it was they used! Maybe used at the end of a magic trick when something disappears...Kazzam!!! "pop"

Super cliche belltree. And reversed cymbal.

I have used eno in a thin metal bowl and rotated the water as the bubbles reverberated off the sides. Very cool sound.

A harp arpeggio, and wind.

Whispy brass instrument

Musically, I'd say harp...

Delicate glass tinkle.

Heavenly choir / voices and any sort of bells.
