Hand pour painted ceramic tiles, backed with a thick layer cork to protect your furnishings. Each coaster is sealed in enamel gloss finish for durability and hot drink protection. High-heat enamel withstands higher temperatures than epoxy resin, the alternative sealant on coasters, so cups won't mark the finishes. Enamel also allows for the texture of the painting to be seen - a huge component of my work. Hope you enjoy!
