Soejima Glassware Handcrafted Cobalt Green Wavy Glass

Hizen Vidro is a hand-blown glass craft from Saga City, designated an Important Intangible Cultural Property of Saga. Its roots reach back to the late Edo period, when the local domain built a glass kiln to make scientific and medical glassware. By the Meiji era the work had turned to lamps and tableware. Soejima Glassware, founded in 1903, is the last remaining workshop keeping the tradition alive. Every piece is shaped by hand without molds, which is exactly why the form and the color fall a little differently in each glass.

Each glass is hand-blown and the five colored layers are shaped by hand, so the rainbow tone and the surface texture vary slightly from piece to piece. No two are identical. The one you receive is its own original.

The color comes from layers of colored glass fused into the body of the glass itself, not from surface paint, dye, or glaze. so there's nothing on the drinking surface that can peel, scratch off, or fall into your drink.

Dishwasher heat and detergent permanently cloud and dull hand-blown glass over time, and the rapid temperature change risks cracking it. Wash by hand in lukewarm water with a little mild dish soap and a soft sponge, then rinse and dry. Skip abrasive sponges, scouring powder, and metal scrubbers (they scratch the surface) and take care inside the glass. Don't force a cloth in and twist it neither, as the thin walls can break.

Yes, cold drinks and ice, as well as a short chill in the fridge, are fine. Just avoid sudden temperature changes and skip the freezer.

Please do not pour in hot liquid nor use it for hot drinks, as the glass may break due to sudden thermal shock (especially quenching).

Please, do not put knives, forks, spoons, etc. in the Soejima Glassware cup or use the glass for storing cutlery or else. It may damage the glass and if the glass is scratched, it will be easily damaged

Also, avoid stacking pieces directly on top of each other. Use soft cloth or felt pads between items to prevent scratches.
