Seize the moment of the flow | Mouth-Blown Glass

Taking a deep breath, a craftsman is blowing air into molten glass. By spinning the blowpipe with their sophisticated hands, a piece of design is well shaped in a minute. This is a very moment destining a glass to be done or gone.

Being time-honored workmanship, glass is one of the favorite materials for the artists. Countless enchanting and diverse objects ranging from glassware to artworks were created of its fluidity and plasticity since B.C. People are fascinated particularly by how the light and shadow refractions play with it. Today, we take on a journey to mouth-blown glasses presented by SEEDDESIGN.

Hand-Blown Glass

Most of SEEDDESIGN’s glass is handmade, mouth-blown by skilled craftsmen. Standing by the hot furnace, the glassblowers dip the red molten glass up to 1200 ℃ with a long steel pipe and move to the mold immediately. They were taught by experience about how much molten to be dipped to make the desired shape.

They start to blow air into the glass and spin the pipe speedily and steadily with hands at the same time to keep the thickness of glass as equivalent as it can. On the other side of the pipe, the glass bubble grows bigger and bigger until it fills up the mold.

The holder opens the mold, cuts off the glass from the pipe and moves it into the tempering oven for cooling down slowly to increase the toughness and avoid hidden cracks of glass. After fine polishing operated in-house exclusively by SEEDDESIGN, a glass of lamp is born.

Since the glasses are made by hands, tiny bubbles, spinning marks therefore exist. None of them weighs 100% the same to one another, instead, these guarantee the natures of mouth-blown glass that every piece of work is unique and irreplaceable.

Colored Glass

When a transparent glass is done in one move, a colored lamp glass takes multiple jobs with 3 to 5 layers which is a big challenge to craftsmen. After a layer of transparency is based, the glassblower dips with molten opaque glass all over top of the base, puts into the mold, and blow air into glass again.

▲ Blowing-up and adding colors into the molten glass at the same time.

Opal glass will be done in three layers, while other colors take five. Usually the inner and outermost layers are transparent that hard enough to protect the color inside. When you gaze at the edge of colored glasses, the opal and the color would be sandwiched in 3 layers of transparent glass.

The colored glass provided by SEEDDESIGN is not painted, but chemical results mixed with different metallic elements. It turns the light into ambiences, each piece differs from one another and does not fade over time.

Sand-Blasted Glass

Sand-blasted glass is one of the features of SEEDDESIGN. It presents the translucency in between clear and opal glass. The process of glass being gently scarred by sand could only be done purely by experienced hands. Light becomes softer, glare-free, and gradient like the sunrise in misty mountains.
