A synthetic ember comprising refractory ceramic wool coated with about 0.10 wt. % to about 5.0 wt. % of an oxidation catalyst of Pt, Pd, Rh, Co, Mn and mixtures thereof for use in small pieces as embers in a gas-fired log set or fireplace. The refractory ceramic wool preferably has a surface area of from 20 to 200 square meters per gram and a density of 0.01 to 0.05 grams per cubic centimeter and the catalytic embers are less than one inch square. The synthetic embers increase heat recoverable at a given BTU from a flame, with reduced nitrogen oxides, hydrocarbons and CO emissions and improved aesthetics.
