Traditional Murano Glass-Making
The key of success for making glass is to take equilibrium in every procedure. Temperature control is also essential to decide the quality. It reaches at about 1200-1300 degrees C when the first load is placed in the furnace. Then all the components together with color and melting agents will be melt at 1700 degrees C. Limestone acts as a stabilizing agent while nitrate and arsenic are added to expulse the air bubbles to make the fusion pure. Next the temperature is lowered to around 1200 degrees C. to allow the suitable viscosity. The fusion is then placed in a slow-baking furnace for a few days to form a workable glob. Any shapes can be applied to this glob by blowing air in. Immersing it in water for several times to remove impurities and enhance the crystallization process. Finally the glass is put in a cooling oven to cool down very slowly to room temperature. This can avoid breaking the glass products due to thermal stress. All these technical but original processes make a unique and colorful Murano Glass product done. {d.j7HA V Fs!L$W
