فنجان شاي من الزجاج المصنفر مزين يدويًا برسمة «الرجال الأربعة» – هدية تنم عن التقدير لعشاق الشاي

Many glass cups on the market are made from ordinary soda-lime glass, which has poor thermal shock resistance. We’ve seen the reviews too—customers report cups shattering the moment hot water touches them, even when the glass was at room temperature. That’s precisely why we chose borosilicate glass for this product. Borosilicate glass is engineered to handle extreme temperature changes. It can withstand boiling water (100°C / 212°F) poured directly from the kettle without cracking, and it can also handle ice-cold beverages immediately afterward. If you’ve been burned by fragile teacups before, these will restore your confidence.

Technically, borosilicate glass can survive a dishwasher cycle. However, we strongly recommend hand washing only. Here’s why: the high heat and harsh detergents in dishwashers can, over time, degrade the hand-painted artwork and may cause clouding on the frosted finish. More importantly, we’ve seen numerous complaints from customers of other brands who put their “dishwasher-safe” glass cups through a cycle only to find them cracked or chipped afterward. Dishwashers also jostle cups against one another, which can chip the rims. A quick hand wash with mild soap and a soft sponge takes less than 30 seconds and will keep your cups looking beautiful for years. Treat them the way you’d treat fine china—they’re worth the extra moment of care.

Yes, the paints used are food-safe and non-toxic. However, we want to be honest with you: no painted surface is truly permanent if you abuse it. The artwork is bonded to the glass through a high-temperature curing process, which makes it far more durable than cheap decals or stickers that peel off after a few washes. That said, abrasive scrubbers (steel wool, rough scouring pads) and harsh chemical cleaners will damage the paint over time. Use a soft sponge and mild dish soap, and your cups will retain their beauty for years. The paint will not leach into your tea or coffee under normal use.

No mistake at all—this size is intentional. In traditional Chinese Gongfu tea ceremony, cups are deliberately small. Here’s why: Gongfu brewing uses a high leaf-to-water ratio and very short steeping times (sometimes just 10–30 seconds per infusion). The tea is meant to be savored in small sips, and the small cup size encourages you to finish each infusion while it’s still at the perfect temperature. A standard Western mug (300 ml+) would cool too quickly and make the tea bitter by the time you finished it. If you’re used to large coffee mugs, these cups will feel tiny at first—but give them a chance. Many tea drinkers find that smaller cups actually enhance their appreciation of the tea’s flavor and aroma. If you prefer a larger cup for everyday drinking, these also work beautifully as espresso cups, sake cups, or whiskey glasses.

This is a fair concern. We’ve seen reviews from customers of other frosted glass products complaining that the texture makes stains harder to remove. Here’s our honest answer: frosted glass does require slightly more attention than smooth clear glass, but it’s not difficult. For daily cleaning, simply rinse the cup immediately after use (don’t let tea residue dry inside). Use a soft sponge with mild dish soap—the soft side, not the scrubby side. For stubborn tannin stains (the brownish buildup from black tea), fill the cup with warm water and add a teaspoon of baking soda or a splash of white vinegar. Let it sit for 15–20 minutes, then rinse. Avoid abrasive scrubbers, as they will scratch the frosted finish. Follow these simple steps, and your Fizz Frosted Glass Teacup will stay crystal-clear for years.
