Our Amiya Oil Warmers feature the master craftsmanship of Blue Pottery of Jaipur, with expertly sculpted designs, intricately hand painted original designs, and lead-free glaze. Pottery is an age-old art in India. Artisans in Rajasthan use a potter's wheel, handmade molds, and their hands to shape natural clay into beautiful works of functional art with a polished finish. This beautiful oil warmer features an original moon phase design brought to life with non-toxic paints. Essential oils are added to the smoothly sculpted top well and warmed by a tealight candle inserted and lit in the open compartment below. This is a simple and elegant alternative to electric aroma diffusers, a lovely combination of form and function.
