wierd flames

Sorry for grammar if there is mistakes :)

I lightned two candles - red and orange. Red ones flame didn't move at all, but orange ones flame moved fast. Why?

Shape of the wick. Different wax. Air movement. I was a choirboy in a Catholic church, and often saw candles burning at different rates, different flames.

Candles were identical except color and those candles were next to each other.

Red pigments found in candles contains metals and elements like lead and zinc which react generally more uniformly during a combustion reaction (a steady flame)while orange pigments contain metals that are more resistant to combustion reaction (like some transition metals like cadmium and chromium), meaning that the flame will often fluctuate and alter its form and direction depending on how combustible the pigment is in certain areas of the wax.
