Toshio IEZUMI was born 1954, in Ashikaga, Tochigi, Japan. After graduating from high school he got the job at a camera company, where he acquired a skill of polishing lenses. In 1983 he began to learn glass art at Tokyo Glass Art Institute and while studying there he started to make sculptures out of sheet glass. Graduated there in 1985, he had developed his unique technique for glass sculptures: laminating sheets of glass into a bloc and carving and polishing it with stone carving tools.
He said that he had felt much impact from the ancient Chinese bronze ware, the works of Constantin Brâncu?i and Donald Judd. Through his technique of direct carving, dealing with the reflection and the refraction of light, he seeks how the illusory volume or depth arises in the glass body. That illusion depends not only on the form of a piece but also on the circumstance, on the positional relation to the viewers. So his works are opened to us constantly varying its appearances.
