This is a handmade ceramic crystalline glazed mug.
"Crystalline glaze is a process of creating or growing a crystal in the glaze
during the kiln firing process. The flower shapes you see on the mug are
crystals we have grown in the kiln. The crystals grow randomly so this truly
makes each mug one of a kind! This particular mug has a seafoam background with
seafoam crystals."
This mug is 5 1/2 inches tall. It can be placed in the dishwasher and microwave.
This mug is marked on the handle, but I could not read it.
Thank you for looking.
