Candles can be produced from various raw materials. Today, most candles currently on the market are made of paraffin, stearin, tallow, or wax. To find out if the base material has any general influence on the emissions of candles, unscented standard tea lights (diameter 38 mm, height 16 mm, aluminum cup) made of paraffin, stearin, tallowand wax are tested under identical conditions to find out if the based material does specifically contribute to the emissions. The non-lit tea lights did not release substances in concentrations above 1 mg/m3. As can be seen in Table 3, all tea lights were weak emission sources after lighting. The emitted substances were non-specific and probably impurities of the base material. Some of them can likely be attributed to Tenax® TA degradation (see 3.5.1). No specific odor could be detected during testing of the candles.
