These 4" diameter tile pillar bases are made by hand in Colorado&';s North Fork Valley using clay from the Paonia Reservoir! This project from our friends at Particular Tile helps reduce excess sediment in the reservoir, ensuring vital water supply for the breadbasket of Colorado. These gorgeous, glazed tiles are backed with cork to offer a beautiful, durable base for our super high-quality beeswax pillar candles. They&';re ideal for 2" and 3" diameter pillars. When not in use as a pillar base, these tiles also make fabulous coasters!
