To all those who swore off candles when TV news programs sensationalized the lead content of wicks several months ago: It's OK. Ergo's wicks are made of cotton. The wax is soy-based and food-grade so that the candles burn cleanly and evenly, which means they stay attractive while burning. The Dallas-based candle maker, which supplies several upscale retail stores, sells its discontinued fragrances and overstocked merchandise at its outlet on Motor Circle near Stemmons from 10 a.m. to 4 p.m. every Saturday. Ergo's most popular scents, including Ch'i, Shanti, Duo, and Zen Temple, are available in a variety of sizes and containers. Choose from the aluminum travel cups to three-wick glass bubble jars at about 50 percent off retail prices.
