Colored Flames

From the Ghost Mines wiki. The following applies to both free burning substances, and those suspended in Methanol. To suspend in Methonol, a saturation amount must be left soaking or stirring in Methanol overnight; longer is better. Please note that Methanol is a biotoxin. Long exposure to the fumes has the same effects as drinking, and can cause blindness. Always use in WELL ventilated areas.|

A ”’Pyrotechnic colorant”’ is a chemical element which causes a flame to burn with a particular color. These are used to create the colors in fireworks. Some common examples are:

{| class=”wikitable”
|-
! Colour !! Compound name !! Chemical formula
|-
| Red || Strontium nitrate || SrNO<sub>3</sub>
|-
| Red || Strontium carbonate || SrCO<sub>3</sub>
|-
| Orange || Calcium chloride || CaCl<sub>2</sub>
|-
| Orange || Hydrated calcium sulfate || CaSO<sub>4</sub>(H<sub>2</sub>O)<sub>x*</sub>
|-
| Gold/Yellow || Charcoal powder || C
|-
| Gold/Yellow || Iron powder with carbon || Fe+C
|-
| Gold/Yellow || Sodium nitrate || NaNO<sub>3</sub>
|-
| Gold/Yellow || Cryolite || Na<sub>3</sub>AlF<sub>6</sub>
|-
| Green || Barium chloride || BaCl<sub>2</sub>
|-
| Green || Barium carbonate || BaCO<sub>3</sub>
|-
| Green || Barium nitrate || Ba(NO<sub>3</sub>)<sub>2</sub>
|-
| Green || Barium oxalate || BaC<sub>2</sub>O<sub>4</sub>
|-
| Blue || Copper(I) chloride || CuCl
|-
| Blue || Copper(II) oxide || CuO
|-
| Blue || Copper carbonate || CuCO<sub>3</sub>
|-
| Purple || Combination of red and blue compounds || Sr+Cu
|-
| Purple || Rubidium</a> compounds (rarely used) || Rb
|-
| Silver/White || Aluminium</a> powder || Al
|-
| Silver/White || Magnesium powder || Mg
|-
| Silver/White || Titanium powder || Ti
|}
The * indicates that the compound will burn orange where x=0,2,3,5.

<p>The color blue is notoriously difficult to produce in fireworks, as the copper compounds need to burn at a specific temperature for the optimal shade of blue to be produced. Thus, a deep, rich blue is usually viewed as the mark of an experienced fireworks maker.
