This cup handmade with a carved mountainscape design to catch pools of glaze in a unique way. The porcelain and glaze is my own formula that resulted from hundreds of tests, these cups are cast from handmade molds. The glaze can vary from glassy to matte with crystals in between that refract light in a beautiful way. The unique nature of the glaze means the piece you receive may vary from the photo, I hope this unique quality is cherished. Microwave and dishwasher safe A very unique cup but also the perfect size for a tea candle.
