Set of 2 beautiful handmade fused glass coasters depicting the symbol Om. Great present for a yoga lover, the Om (or Aum) is the symbol of the Absolute. Each coaster measures approximately 4 inches by 4 inches and is backed by a protective cork backing. The backing can be removed if you wish to use the coaster as an accent tile. The symbol is represented in and framed in a pale mauve glass with a black background. Each coaster is made up of over 30 individually cut pieces of glass that have been fused and annealed in my kiln. The glass has been left partially raised to prevent condensation pooling and your cup or glass sliding off.
