Established as a manufacturer of light bulbs in 1922, Shotoku Glass were originally renowned for their niche technique in mouth-blown glass. As the light bulb industry automated, Shotoku Glass shifted to manufacturing glassware, concentrating on the production of mouth-blown glasses of several thousand kinds. Shotoku Glass is most known in Japan for their “Edo glass” – a small beer glass that is admired for its handiness and delicate strength, earning a high reputation with top restaurants and the hospitality industry. With a long and rich experience in mouth-blown glasses, Shotoku Glass has succeeded in creating an ideal series of very thin glassware.

All Shotoku glasses are made using the method of mould-blowing: blowing air into molten glass and using metal moulds to create products of the same shape. A piece begins when the glassblower extends their blowpipe into the glass furnace to gather a layer of molten glass. Once ready, the blowpipe is withdrawn, and the air is blown through the pipe to form the glass into a small ball.

A skilled glassblower then extends the blowpipe, with the molten ball of glass, back into the furnace, rolling it round and round to gather the appropriate amount of glass depending on the eventual size of the product to be blown. The molten glass is withdrawn and placed inside a bowl-shaped mould, after which the glassblower lifts the blowpipe upwards and blows air through it. This process requires long experience and distinctive design skill.

To prevent the mouth-blown glasses from cracking or breaking due to rapid cooling, they are instantly placed into a special glass kiln called a lehr that operates at a starting temperature of around 500 degrees Celsius. The glasses move slowly through the lehr on a conveyor belt, gradually being cooled down to room temperature. Every piece is subject to precise quality control.

A straight line is first etched into the glass with a diamond wheel cutter to the required height. The glass is then set on a rotating base and is exposed to the burner flame along the straight line previously etched. Being specifically heated along the line allows the excess glass above, where the molten glass was once attached to the blowpipe, to be cracked off by hand from the body
