Exothermic, for within an endothermic (situation) there would be a drop of temperature *excuse my spelling if you would* , therefore to continue burning it will need to absorb the heat, where as exothermic reactions energy will be released as heat.
Burning flames and explosions typically occur in exothermic reactions where heat is released, such as combustion reactions. These reactions involve a rapid release of energy in the form of heat and light.
Burning silver in a flame test typically produces white or bright blue flames due to the presence of silver ions in the compound.
Burning dry material produces larger flames which makes the fire brighter. Anything dry enough should produce a nice bright flame.

When concrete cures it warms up. Those hand warmers that heat up when they are opened up are exothermic. Desiccants when exposed to a lot off water.
The hotter the flame, the less color (and light) given off. Bright, yellow flames are the result of carbon that has not been burned, where blue flames indicate a near total burning of the fuel. Other chemicals present in the wood can color flames- sometimes added for the appearance- red, yellow, blue, green.
A burning bush typically appears as a shrub or small tree engulfed in flames, yet it does not turn to ashes or burn away. The flames can be bright orange and yellow, contrasting against the green foliage. In a symbolic or artistic representation, it might be depicted with a radiant glow, emphasizing its miraculous nature. The scene often conveys a sense of awe and divine presence.
Burning Engulfed in flames Inflamed
Crackling, popping flames.

Because they finished burning up.
Flames don't have shadows because they emit light and heat, making them too bright to cast a shadow.
