Margaret Joplin Cast Glass


Goldsmithing is still a passionate hobby of Adam’s.  On weekends, he ducks into the garage  and pounds metal into beautiful, wearable art.  When we see craft that reminds us of our “jewelry days,” we get excited.  These cast glass works are made by one of the same processes jewelry is – the “Lost Wax” process.  These stunning architectural home and garden pieces made by artist and garden landscape designer, Margaret Joplin, caught our attention at the Dwell on Design Show this summer.
