ABSTRACT:
A gas log set for a fireplace has sets of gas jets arrayed to provide a pleasing distribution of flames around and between several cast-concrete simulated logs. A glowing-ember effect is created beneath a front log and between the logs by strips of rock wool which radiate when heated. Both the simulated logs and the rock wool are doped with metallic salts which convert the complete-combustion blue coloration of a gas flame to a yellow-orange color which closely simulates the appearance of a natural wood fire.
