I visited the glasswork exhibition at Fukui Kougeisha Craft Gallery and interviewed the glass artist, Mr. Yoshitaka Tajima, who has a studio in Maruoka Town, Sakai City, Fukui Prefecture. He uses varied techniques such as lampworking, fusing(kiln working), sandblast and stained glass, produces many different kinds of original glassworks. At the exhibition, the glass instruments for calligraphy displayed at the center of the gallery and the colorful glass pens caught my eye.
