Colored glass is a coloring agent added to ordinary glass. The amount of coloring, the melting time and the melting temperature will affect the depth of the burned color to varying degrees. A colloidal colorant such as gold, silver, copper, selenium, sulfur, or the like is used to suspend very small particles in the vitreous to color the glass. No flux is added to the colorant during the firing process.
Its production process is not particularly complicated. It first goes to the market to buy a professional library of tempered glass, then processes and controls the desired image through computer software, and then paints it through some digitally-painted printing equipment, and strengthens it. The special ink is colored and integrated with a special film to make a very ordinary glass interesting and interesting. The modern painting method eliminates the need for an oven and saves time. Without the need for a canvas, beautiful pattern painting can be done at any time.
