Brand Story
“I used to think glass was just a container, until I saw the time it carried.”
The family's 30-year-old multi-colored glass craftsmanship is on the verge of disappearing as the master craftsmen grow old.
This industry is too old—the average age of craftsmen who master the core techniques of multi-colored glass nationwide is 58.
Over the past decade, we have crafted tens of thousands of glassware pieces for international brands, yet we couldn't retain a single apprentice from the post-90s generation. Machines can be imported, but the sparkle in a master craftsman's eyes cannot be replicated.
In 2025, I resigned from my promising career in the renewable energy sector and boldly entered the uncertain field of stained glass craftsmanship.
May the art of stained glass be recognized and cherished by more people.
The Night Watchman Before the Furnace
At 50°C next to the high-temperature furnace, a precision difference of 0.1 millimeters is the last stubbornness of the master craftsmen.
In the spring of 2025, Master Chen from the cutting workshop pointed to the yellowed work record book and said, “This trade will die out once our generation retires.”
Behind him is a continuously burning 50°C high-temperature furnace. The craftsmen need to stand continuously for 8 hours to blow the multi-colored clay bodies.
Then, spend another 12 hours holding your breath in front of the cutting machine, carving away—if the error exceeds 0.1 millimeters, the entire piece will be scrapped.
What keeps the craft alive is never the display cases in museums, but the flames that are passed on from one person to the next in front of the furnace.
Craftsmanship Techniques
Hand-blown Selecting materials - Small bubbles - Large bubbles - Skin coating - Shaping - Fire polishing
Immerse the transparent glass blank (blown to the size of a pear) into cobalt blue glass liquid at 1250°C, rotate it evenly three times, then pause for five seconds to allow the colored liquid to flow evenly under gravity into a uniform layer of 1 mm. The craftsman must maintain the technique of three rotations and five pauses to ensure that the thickness error of the colored layer is <0.1 mm and the light transmittance deviation is ≤3%. Then, use an oxygen-propane torch (1400°C blue flame) to sweep over the 850°C glass surface, with each exposure lasting ≤3 seconds, to enhance the glass's transparency.
Hand-carved Design - Marking - Rough carving - Fine carving - Rounding - Polishing
First, use a dividing device to draw a reference line on the glass surface as a basis for carving positioning.
Second, use a grinding wheel to carve the general texture, controlling the force and angle to form the “framework.”
Next, switch to a fine grinding wheel to refine the details. Mistakes at this stage can result in the entire piece being scrapped;
Finally, remove any cutting marks to achieve a smooth and translucent surface. Additionally, craftsmen require over ten years of experience to perform consistently, relying on muscle memory and spatial imagination. Especially for complex patterns (such as chrysanthemum motifs), precise angle calculations are necessary to avoid visual imbalance. The depth and angle of cutting directly affect the refraction effect.
