It's always a pleasure when I am allowed to go inside a glass factory in Murano. For security reasons, these places are "off limits" for everybody, but sometimes I find a way through and I spend a morning taking pictures of very ancient art. This is the making of the glass cane that hides the colored "Murrine", the images or patterns made with glass. These patterns (since the Roman empire) will widely be used for making jewelry, glass vessels, jars, and so on.
