This sandglass is a 1-minute tea timer. Pale green color sand tells you when 1 minute has passed. The sand inside was designed to be similar to the color of fine tea. Japanese green tea should be brewed for a specific length of time for ideal flavor. Sencha should brew for 1 minute, and Gyokuro should brew for 1.5 to 2 minutes.
About 50 years ago, there were many factories which produced glassware, such as fairy lights, and artisans made SUNADOKEI by hand. Today there are only 3 factories which produce SUNADOKEI in Japan. We asked one of them to make our sandglass as an original product. All of the products are handmade at the factory.
As the glass tube is repeatedly turned while heated by a burner, it is finished into a gourd shape. Finishing the center narrow part, called HACHI no KOSHI, a bee’s waist, is difficult and requires delicacy of hand, concentration and subtle force. It is a true artisan's skill to finish this part in a short time.
The diameter of the sand path is adjusted according to the size and time of the sand grains to be placed inside. This is adjusted by heating it again with a burner.
Then, the entire piece is reheated and cooled to make the glass less likely to break. Finally, sand is added, the seconds are measured and checked, and one side of the empty glass opening is closed to complete the process.
Since each piece is handmade in this way with much time and effort, there may be slight irregularities in shape, tilt, etc. These individual features make each piece unique. You can sense that it is made by hand, and appreciate the work of the craftsman.
