The juice is extracted from canes by squeezing them between rollers.
Owing to this property, tubes or canes can be produced with a square, oblong, oval or triangular section.
The canes from which the patterns are formed are either simple or complex.
The process can be almost indefinitely repeated and canes formed of extreme complexity.
A vase decorated with these simple or complex canes is produced by embedding short lengths of the cane on the surface of a mass of molten glass and blowing and fashioning the mass into the required shape.
