I'd done my research, but nothing prepared me for what I was about to witness. The glassmakers' fornaci were already alive with activity. Through ancient wooden doors, glimpses of fire danced in massive furnaces. Inside the workshops, maestri worked their magic, transforming molten glass the color of sunset into delicate forms. The air shimmered with heat as they manipulated gather balls glowing at 1200 degrees. Their practiced movements created streams of cobalt blue, swirls of aventurine gold, and clouds of milky lattimo white.
Through the open door of Vetreria Artistica Colleoni, I saw him - a man in his sixties, his forearms thick as tree branches, performing what looked like a choreographed dance with molten glass. The furnace roared at 1500 degrees Celsius, its mouth glowing orange like a miniature sun.
"Permesso?" I called out, hovering at the entrance.
"Entra, entra!" He beckoned without taking his eyes off the glowing mass at the end of his metal rod. His name was Marco, I would learn later, third-generation glass master.
The workshop was a theatre of heat and precision. Marco moved with the confidence of someone who had done this dance thousands of times before. He rolled the molten glass on a metal table called the marver, shaping it with tools that looked medieval. Every few minutes, he would return the piece to the furnace, spinning the rod continuously to keep the glass from drooping.
"Watch now," he said in accented English, his eyes twinkling. With a series of seemingly simple movements, he transformed the glowing blob into a delicate dolphin, its tail curved in mid-leap. The metamorphosis happened so quickly, so naturally, that it seemed like magic.
