Quartz glass is made from silica and has a high level of purity, among other superior characteristics. Deriving its name from the process of melting quartz powder to make glass, the material can withstand temperatures up to 1000 degrees Celsius and is resistant to chemicals. Used in the production of semiconductors and optical fibres, the alluring glass possesses endless clarity.

The urushi tree grows in Japan, China and south-eastern Asia. Urushi lacquer is produced by refining the tree’s sap by adding iron powder, which oxidises and turns the liquid black. Pigments are then added to make vermillion and other coloured lacquers. Gradually hardening and gaining strength, the lacquer possesses high water resistance, thermal insulation and antibacterial properties. However, the material’s greatest quality lies in its smooth, lustrous appearance. Durable and decorative, urushi has long been used for practical items, such as tableware, as well as in shrines and temples. Even today, lacquer artisans remain a feature of the production landscape in many parts of Japan.

Founded in 2011 in Shioya, Tochigi prefecture. Formerly a supplier of manufactured stones, the company renewed its business under the leadership of current president Toshio Saito. Leveraging its expertise in cutting and polishing stone, the company now produces high quality quartz glass and optical glass, crucial components for state-of-the-art precision machinery and semiconductors. The Quartz Glass series began with the cutting and polishing of Japan’s largest piece of glass, 7 metres high and weighing 4.3 tons, which was truly a sight to behold.

Founded in 1940 in Takaoka, Toyama prefecture, a city famous for its lacquerware. In an industry where the division of labour is standard, the company stands out for handling the entire manufacturing process, from wood fabrication to the final lacquer coating, for dinnerware, doors, ceiling panels, glassware and other products. The Quartz Glass series, in which lacquer and glass are divided by a clean, straight line, draws on the expertise of the company’s third-generation president, Yasuyuki Komai, in both lacquerware and mother-of-pearl inlays.
