How It's Made
Glass Spoon Pipes

Despite their straightforward nature, making hand pipes requires a large amount of training and experience. Glass artists start with a tube about four inches long and decorate it with a variety of techniques such as fuming, linework, etc. Next the artist starts to create the shape of the pipe by stretching the neck and forming the mouthpiece. The artist then carefully blows into the end of the tube to expand the glass and shape the bowl. They then push the bowl and pop the carb before placing it in the kiln to finish!
