"Ozma" from "The Gnome King of Oz" by L. Frank Baum
(Ozma is a character in the book)
The colored glass symbolizes the gems in the earth mined by the Gnomes. Ozma is the lost princess of Oz and the green glass represents the Emerald City. The granite and granite type pottery/china is indicative of the Gnome King's kingdom.
Well, it seems appropriate that I would post a pic of one of my broken china hearts to celebrate the day. I'm about to embark on another learning experience with 10 and 11 year old girls making them for the first time. It's going to be so fun! I'll post a pic in a few weeks to show them off to everyone. Just like to keep everyone anticipating something exciting.
