Each chemical element has its own Identity given by the color emited when it is burning. The colors in fireworks is due a diferent kind of elements. Copper give the color green, sodium give the yellow one. This video shows a lot of diferent elements and its correspondent colors.
Glycerine or glicerol is oxidized by a very powerfull oxidant, the potassium permanganete. This reaction liberates a lot of heat, it's called exothermic reaction.
Learn about science and you make your own butter. Science has never tasted so good.
