Candles should be placed on a solid surface, preferably metal or glass. Any stable surface that's away from flammable items is ideal. Avoid wood and plastic surfaces or paper-based surfaces as they heat up and become flammable. Glass and metals have higher melting point making them safer surfaces for candles. Also, we recommend that you avoid placing candles on wire racks since they can fall off balance and create a fire hazard.
Lastly, please remember to use candle holders or coasters whenever possible.
