<tc>Pair of green circle glasses</tc>

The art of Balearic glassblowing dates back to the 2nd century BC and consists of introducing an iron tube (the canya) into a quantity of molten glass. The opposite end is then blown and the glass is blown up as if it were a balloon. To work this 'balloon', the tube is turned in both directions and the blower gives it shape using wet newspaper, moulds, different instruments, or even by hand. When the piece is finished, it is separated from the tube. The puntill is what remains of the union between the cane and the object, and can be seen at its base.
