目次 Colorful glass worksLarge plates and receptacles. Many pretty colors are used, and one look and you’ll be fascinated. However, Hisao Nabeta’s works are not only that. The receptacles have beautiful curves, and the colors ”flow” in the glass. The flowing colors are made using a technique to combine different colored glass, and heat and melt them together. The method he explained was surprising. He uses gravity to transform the shapes. First, glass plates or glass sticks of different colors are combined to determine a design. A mold made of fire-proof plaster with a hole is prepared, and legs are attached underneath. The colored glass pieces are placed on the mold, and placed in an electric oven. As the temperature rises, the glass melts slowly, and by the force of gravity, gradually stretches down the hole. This creates the flowing form of the receptacles. |
Taking time to slowly form the receptaclesWhen we observed at the glass that had cooled after it was taken out of the oven, we understood what Nabeta meant by gravity. The molten glass is made to slide into the plaster mold. It’s very interesting, but it is an extraordinary procedure. Imagine a vase, for example. A vase with distorted shape may be charming, but Nabeta’s vase has a very refined curve. To produce that shape, the molten glass must sink evenly into the plaster mold. The glass has to be heated very slowly for this to happen, much slower than the process used for other glasswork. |
Expressing ”wa” through glassThe technique Nabeta mainly uses is called fusing, where designs are created by combining glass sticks. It is an old technique, but one that requires high degree of skills because the expansion rate of glass varies when heated. As a result, it gradually gave way to glass blowing. Nabeta also uses glass blowing and other techniques. |
