Kate and I discovered a flaw in Rick's assessment. We went into several shops and asked for their demos. They looked at us like we were freaks. "No", "broken", or a wait of several hours were the typical response. When we finally found a glimpse of a 'fornace' from outside, we were hopeful. We patiently waited in line until eventually we worked our way up to the front. At that point, however, the glass-blowers turned off the music, turned out the lights and yes, went to lunch.
Never ones to give up, we kept wandering aimlessly, and found ourselves in a rather expensive shop, CAM. The saleslady motioned us back into the courtyard, checked the fornaces which were empty and told us to wait 5 or 10 minutes. We started hearing voices, seeing movement, and suddenly things began to happen. The best part was that we had a private glass-blowing demonstration, just Kate and her Aunt Nancy.
A team of four artisans worked together, in what appeared to be a master, an apprentice and two assistants. They worked quickly with the malleable material, measuring with simple calipers to the precise dimensions. Their tools had textured edges for forming. The master showed us a photo of the chandelier that they were 'constructing', and we watched them blow several different globes.
Sweat was pouring down our foreheads from the heat of their forges, so I can only imagine how they felt. They would occasionally dip the steel rods in water to cool them off, and steam would rise in clouds.
