Among Okinawa's many traditional crafts, it is a new craft with a relatively short history. It began to be mass-produced shortly after the war, when it began to be made for American military personnel stationed there. It is said that the colorful Ryukyu glass that continues to this day was born by recycling empty soft drink bottles discarded by American soldiers who occupied Okinawa at the time. The development of Ryukyu glass...Due to the historical background of the American military continuing to be stationed there even after the war, Ryukyu glass achieved remarkable development. At that time, the main raw material for Ryukyu glass was recycled glass. It was thick and had air bubbles in the glass, and the main color was not the bright, primary colors that we see today, but rather a dull transparent color. However, it lacks the transparency, coldness, and delicacy that are typical of glass found in other glassware, and its deep color and unique bubbles are more appreciated as an Okinawan charm, and it has continued to this day. Ta. Air bubbles, which would normally be treated as defective products, are a characteristic of Ryukyu glass, and even today, as more and more workshops use glass as a raw material, it has been passed down as a simple taste and art of light. The heart of a Ryukyu glass craftsman...The manufacturing methods for Ryukyu glass include ``air blowing,'' in which the glass is wound around the tip of a blowing rod and blown into shape, and ``mold blowing,'' in which the glass is blown directly into a mold. . The glass blowing process during molding must be completed before everything gets completely cold. The glass is heated to 1,400 degrees and melts to a melting consistency, constantly moving like a living thing. The work requires you not to relax even for a moment, It will be hotter than you can imagine. Under such circumstances, by tuning in to the movement of the glass, which seems to have a will, and facing the inherent characteristics of glass, the colors and brilliance of Ryukyu glass that go beyond the intentions and techniques of its creators are born. .
