Manganese stays clear in glass except when placed in direct sun where it causes it to oxidize turning it purple. This vase belonged to my grandmother who as far back as I remember had it sitting in a window in direct sunlight. This antique vase is dainty and lovely. I did not clean it because it looks cool. It measures 2-3/4 inches diameter and 4-7/8 inches tall.
