TECHNIQUE Mouth-blown glass
Glassmaking was first discovered by chance around 4,000 years ago, when
sand was mixed with wood ash, perhaps while potters heated clay at high
temperatures. In 50 BCE, Mediterranean people discovered mouth-blowing,
the fastest way to make glass in different shapes and sizes. They rolled
the end of a pipe in molten glass, and then blew into the pipe to form a
bubble. From there, tools could mould and add texture to the glass.
New techniques have been introduced, but mouth-blowing has not changed much. The technique of mouth-blowning glass is used to control the shape of glass – made from silica (sand) and alkaline materials, which are heated to a liquid then quickly cooled – producing beautiful irregularities that make each piece unique.
