The Ancient Mastery of Craftsmanship: How a Masterpiece Is Born Every single vase comes to life amid the flames of the furnace, through precise and empathetic gestures handed down by generations of masters. Processing generally takes place as follows: Very high temperature glass melting: The mixture of sands and minerals is melted in crucibles until it becomes an incandescent and malleable mass. Mouth blowing via glass barrel: The master blows air through the traditional barrel, giving life to the core and first shape of the bulb. Inserting color or decorative fragments into the warm glass: When the body is still hot, the grits are applied creating a constellation of multicolored spots that float on the glass base. Manual neck and upper tip shaping: Using pliers, scissors, and historical tools, the mouthpiece is opened hot freehand, creating the characteristic and dynamic uneven corolla shape with unique impulses. Slow cooling in the oven to prevent breakage: The pot is finally stored in a tempera oven for a gradual drop in temperature, a critical step in eliminating internal stresses and ensuring maximum crystal stability.
