The exhibit of Tsuchiya Koto (土屋琴)'s glass art was at at Gallery-G2b. (The gallery has two display spaces - one G2a and the other G2b.) I spoke with the artist and another artist there for a little - about culture-jumping, and the large glass piece depicted on the promotional postcard below.
The glass piece above is one piece (not two pieces joined together, as I had thought it might be). After making the glass, it was painted in order to get it jet black.
