- Bright GREENS are made with barium.
- Deep REDS are a product of strontium.
- BLUES come from copper.
- YELLOWS require sodium.
MORE COLORS CAN BE CREATED BY MIXING COMPOUNDS:
- ORANGE is produced by a mixture of strontium and sodium.
- SILVERY WHITE by a mixture of titanium, zirconium and magnesium alloys.
- LAVENDER is obtained using a copper and strontium mix.
SPECIAL EFFECTS ARE CREATED BY YET OTHER MINERAL PRODUCTS:
- Iron filings (from the ore mineral hematite) and small particles of charcoal produce GOLD sparks.
- Bright flashes are created by using fine ground aluminum powder.
- The use of larger particles, such as small flakes or granules, give a longer, shower-like effect.
- Magnalium, a magnesium-aluminum alloy, produces a tiny series of silvery-white flashes.
- Aluminum, antimony sulfide and perchlorate are other flash mixtures that are used.
Fireworks are just one more example of how we use minerals for the manufacture of everything from automobiles to toothpaste.
