A glass tea cup is a modern and elegant alternative to traditional ceramic or porcelain ware. It is favored by tea enthusiasts for its ability to provide a full sensory experience, allowing the drinker to admire the color, clarity, and "dance" of the tea leaves as they steep.

1. Types of Glass

• Borosilicate Glass: This is the gold standard for tea cups. It contains boron trioxide, which makes it highly resistant to thermal shock. You can pour boiling water into a cold borosilicate cup without the risk of it cracking.

• Double-Walled Glass: A popular modern design where two layers of glass are fused with a vacuum layer in between. This creates an insulation effect, keeping the tea hot for much longer while the outer surface remains cool to the touch—eliminating the need for a handle.

• Soda-Lime Glass: The standard glass used for everyday drinking. While clear and beautiful, it is more sensitive to extreme temperature changes and is usually thicker to compensate for durability.

2. Key Features

• Non-Porous Surface: Glass is completely non-reactive. Unlike some unglazed ceramics, it does not absorb odors or flavors, ensuring that a delicate Green Tea doesn't taste like the Masala Chai you had earlier.

• Visual Appeal: It is especially popular for serving blooming teas, herbal infusions, and "Everytime" style specialty lattes where layers of milk and tea are visible.

• Stain Resistance: While tea can leave a film (tannins) on any surface, glass is incredibly easy to clean and shows exactly when it needs a rinse, maintaining a high standard of hygiene.
