Whether you are a seasoned tea master or a curious newcomer, this Handblown Borosilicate Tea Pitcher will elevate your practice, bringing clarity—both literal and metaphorical—to every cup you pour.

The Story of Balance: The Gong Dao Bei and the Spirit of Equity

The Gong Dao Bei (公道杯), often translated as “Fairness Cup” or “Justice Cup,” has a history as rich as the tea it serves. Originating in the Chinese Gongfu tea ceremony, its primary purpose is to collect the brewed tea from the teapot or gaiwan and then distribute it evenly among the guests. This practice ensures that everyone receives tea of the same strength, temperature, and flavor profile, eliminating any advantage of being served first or last. The name itself—Gong Dao (公道)—means “fairness” or “justice,” reflecting the Confucian ideal of equity and harmony in social interactions. The Glass Gong Dao Cup embodies this philosophy. Its transparent walls allow you to observe the tea’s color and clarity, and its built-in filter (or the ability to hold a separate filter) helps to catch stray tea leaves, ensuring a clean, sediment-free pour. The sea horse motif is not arbitrary; in many cultures, the sea horse is a symbol of patience, contentment, and gentle strength—qualities that resonate deeply with the tea ceremony. By choosing this Fairness Cup Teaware, you are aligning yourself with a tradition that values equality, mindfulness, and the beauty of shared experience. Every time you pour from this cup, you are participating in a centuries-old practice of hospitality and respect.

The Art of Fire and Breath: Handblowing Borosilicate Glass

Creating the Glass Gong Dao Cup is a dance between human skill and elemental forces. The process of handblowing borosilicate glass is a demanding art form that requires years of training, a steady hand, and an intuitive understanding of the material’s behavior under extreme heat. Here is how our master artisans bring this cup to life:

1. Gathering the Molten Glass: The journey begins with a furnace heated to over 1600°C (2912°F). A long hollow pipe, called a blowpipe, is dipped into the molten borosilicate glass. The glass gathers on the end like honey, glowing orange-hot. Borosilicate glass is chosen for its low coefficient of thermal expansion, making it highly resistant to thermal shock—perfect for withstanding the sudden temperature changes of hot tea.

2. Shaping the Blank: The artisan rolls the gather on a steel table (marver) to cool it slightly and shape it into a rough cylinder. Air is gently blown into the pipe to create a bubble inside the glass. This initial bubble is the foundation of the cup’s cavity.

3. Adding the Sea Horse Motif: While the glass is still malleable, the artisan uses specialized tools to apply additional molten glass to form the sea horse design. This is done by attaching small gathers of glass and sculpting them with tweezers, shears, and paddles. The sea horse is built up layer by layer, creating a subtle three-dimensional relief that is both tactile and visual. The heat must be maintained precisely; if the glass cools too much, it will crack; if it stays too hot, the details will melt away.

4. Blowing and Expanding: The artisan continues to blow and rotate the pipe, expanding the glass bubble into the desired shape—a wide, stable base with a tapered neck and a graceful spout. The dimensions are constantly checked against a template to ensure consistency. The 175ml capacity and 10cm x 7.5cm footprint are achieved through this careful manipulation.

5. Attaching the Handle: A separate gather of glass is used to form the handle. The artisan heats the area where the handle will attach, picks up a blob of glass, and pulls it outward, shaping it into a loop. The handle is then fused to the body with a torch and smoothed to eliminate any seams. This requires split-second timing to ensure a strong, invisible joint.

6. Annealing: The Slow Cool Down: Once the cup is fully shaped, it is placed in an annealing oven (lehr) that slowly cools the glass over several hours. This process relieves internal stresses that could cause the glass to shatter later. Proper annealing is what gives the Heat Resistant Glass Teapot its durability and longevity.

7. Polishing and Inspection: After cooling, the cup is inspected for any imperfections—bubbles, cracks, or uneven thickness. The rim is polished to a smooth, comfortable finish. The sea horse motif is examined for clarity and definition. Only cups that pass this rigorous inspection are stamped with the Junxistea mark and packaged for shipment.

Glass Gong Dao Cup: A 4-Point Journey to Perfect Tea Service

1. Understanding the Role of the Fairness Cup

The Glass Gong Dao Cup is used immediately after the tea has been steeped in the teapot or gaiwan. Instead of pouring directly into individual cups (which would result in uneven strength—the first cup being weaker, the last stronger), you pour the entire brew into the fairness cup. This mixes the tea thoroughly, ensuring a consistent flavor profile. It also allows any fine particles or leaves to settle at the bottom of the fairness cup, preventing them from entering the drinking cups.

2. The Pouring Technique

Hold the Handblown Borosilicate Tea Pitcher by its handle, tilting it gently to pour the tea into your guests’ cups. The spout is designed to provide a smooth, laminar flow without dripping. Pour in a continuous motion, filling each cup to the same level. The transparent glass allows you to see the exact amount of tea remaining, helping you judge when to stop. This visual feedback is invaluable for achieving perfect portion control.

3. Observing the Tea’s Character

One of the joys of using a glass fairness cup is the ability to appreciate the tea’s liquor. The crystal-clear walls of the Glass Gong Dao Cup reveal the true color of the tea—whether it’s the pale gold of a white tea, the amber of an oolong, or the deep ruby of a black tea. You can also observe the “tea legs” (the viscosity of the liquid) and any cloudiness that might indicate over-steeping. This visual analysis deepens your understanding of the tea and enhances the sensory experience.

4. Cleaning and Care

After use, simply rinse the Glass Gong Dao Cup with warm water. The smooth, non-porous surface of borosilicate glass resists staining and odors. For stubborn tea stains, a gentle scrub with a soft sponge and a little baking soda will restore its sparkle. Avoid abrasive cleaners or metal scrubbers that could scratch the glass. The cup is dishwasher safe, but hand washing is recommended to preserve the delicate sea horse motif. With proper care, this cup will remain a cherished part of your tea set for years.

5 Reasons Why the Glass Gong Dao Cup Is Indispensable

• Ensures Perfectly Balanced Tea Every Time: The primary function of any Fairness Cup Teaware is to homogenize the tea liquor. By mixing the entire brew before serving, you guarantee that every guest experiences the same flavor intensity, temperature, and aroma. This is the essence of Gongfu hospitality.
• Exceptional Heat Resistance and Durability: Made from high-quality borosilicate glass, this cup can withstand boiling water without cracking. It is also resistant to thermal shock, meaning you can safely pour hot tea into a room-temperature cup. This durability makes it ideal for daily use and travel.
• Stunning Handcrafted Sea Horse Design: The sea horse motif is not a decal or etching but a sculptural element integrated into the glass during the blowing process. This gives the cup a unique, three-dimensional quality that catches the light and adds a touch of marine elegance to your tea table. It is a conversation starter and a work of art.
• Optimal Size for Versatile Use: With a 175ml capacity and compact dimensions (10cm x 7.5cm), this cup is perfectly sized for small teapots (100-200ml) commonly used in Gongfu brewing. It is also suitable for serving individual portions of cold brew or even as a small milk pitcher for coffee. Its versatility extends beyond tea.
• Crystal Clarity for Visual Appreciation: The transparency of borosilicate glass allows you to fully appreciate the color and clarity of your tea. You can see the liquor’s depth, observe any sediment, and even watch the tea leaves dance as you pour. This visual aspect is an integral part of the tea experience, often overlooked with opaque teaware.
