The Glass Beads' Manufacturing Process and

Japanese Artisan Skills

Initially, glass materials such as high-quality silica powder and sodium carbonate are mixed with coloring agents.

When the raw materials are heated to 1300 C (2372 F) in a melting furnace for 20 hours, they transform into a glass material with a malt syrup-like appearance. The glass that melted into a malt syrup-like appearance is removed from the melting furnace. A special machine expands the glass while air is being blown into the core of the glass, forming an extremely thin glass tube.

Then a blade that rotates at high speeds cuts the glass tube. The glass is heated in a rotating furnace at approximately 700 C (1292 F) to melt the edges of the cut glass tubes to form round beads. Stains such as charcoal and ashes on the bead surfaces are gently washed off using pure natural water acquired locally, which is then dried with hot air. The beads whose surfaces with a "frosted" (polished form) texture are exposed to an electric furnace at 700 degrees C (1292 F) to melt only the surfaces for a beautifully shining glossy finish.

Finally, the color-adding steps are applied once or several times to express the beauty of vivid color variations on each bead where some of the finishes include the touch of jewel beetles, chrome, luster, and aurora.
