Crackling microstars

[Bigfatorange]

Hi does anyone know if there is a difference in the loudness of the crackle in these two formulas

 

bismuth trioxide 37.5%

copper(II) oxide 37.5%

magnalium 25%

+10% NC

 

Bismuth trioxide 75

Magnalium (-200 mesh) 15

Copper (II) oxide 10

Aluminium (200 mesh atomized) 5

 

If so which one is louder

Thank you
