Provided is an oxygen generating composition comprising a metal powder fuel, a transition metal oxide catalyst, a reaction moderator, a binder, an additive, and an oxygen source. The additives are feldspar or anhydrous aluminum silicate, or both. The oxygen generating composition can be used to generate oxygen on thermal decomposition. The oxygen generating composition is suitable for incorporation into oxygen generating candles. Oxygen generating candles of the present invention have the advantages of lower chlorine concentration, better reaction rate control, and lesser sensitivity to temperature effects on oxygen generation when compared with conventional oxygen generating candles. Additionally, oxygen generating candles comprising the compositions of the present invention can result in candles that do not contain barium compounds, and are non-hazardous, stable to moisture, CO<SUB>2</SUB>, and to air, and are suitable for either wet or dry processing methods.
