Majorcan Arts & Crafts-Glass Blowing The art of glass blowing is

quality with the famous Murano glass. The process of glass
blowing consists of placing an iron tube (normally between 1
meter to 1.45 meters long) into a mass of molten glass ( around
1200 ºC to 1600 ºC), and blowing down the tube inflating the
glass as through it were a balloon. The glass is composed of
silica sand, sodium carbonate and limestone. It ´s revolved on
the tube while the molten material is pulled into the desired
shape with tongs. The tools used on the process of glass blowing
will be iron tubes, tongs, blades, tweezers and scissors. When
the glass piece has the desired shape, they separated the piece
from the blowpipe, twisting the piece with a blade. Once the
glass piece has been made, the temperature is decreased
progressively in the furnaces, to avoid breakage or cracks due
to sudden temperature changes. I
