The method that Toshio Iezumi uses to create his elegant sculptures is not unlike carving stone, except that he doesn't use a chisel. First, he laminates a set of glass plates into a large mass; this is his "stone". Next, he uses a diamond-bladed saw to cut the mass into a rough form. Then, he uses a series of six increasingly-fine hand grinders to refine the outer surface of the form. Finally, he uses a felt buffer to polish the surface to perfection.
The result of all of this long and arduous effort is a quite piece that shouts refinement... the shape and contours of the work cause it to reflect and refract light in myriad ways. The greenish tint of the glass (a result of the iron added to ordinary plate glass to give it strength) appears strongly or not at all, depending on the angle of viewing and the amount of light present. And the outer surface of the work is perfectly smooth. (The seams between the plates of glass in the work are only visible if you look at the work edge-on, or in just the right light.)
However, because of Toshio-san's considerable skill in working the glass, the surface creates wonderful effects using whatever light intersects it. The simplicity and grace of this work is spectacular.
