Yes, each cup is handcrafted using traditional Jianzhan techniques that date back centuries. The artisan shapes the cup on a potter's wheel and applies multiple layers of iron-rich glaze by hand, ensuring no two pieces are exactly alike.

The glaze contains high-iron clay that forms natural oil-spot and crystal patterns during high-temperature firing in a reduction kiln. This creates a distinctive grain-like wood texture with subtle variations, making every cup a one-of-a-kind piece of functional art.

You can use it for both hot and cold drinks, including craft beer, cold brew, sake, cocktails, shots, and even espresso. The cup is thermal shock resistant due to the high-fired stoneware, so it handles temperature changes well without cracking.

Absolutely, the glaze is lead-free and completely food-safe because it is fired at extremely high temperatures, which vitrifies the clay and seals the surface. It is non-porous and resistant to absorbing flavors or odors from acidic beverages.

Hand washing with mild soap and a soft sponge is recommended to preserve the glaze's natural luster and texture. Avoid abrasive scrubbers or dishwasher detergents, as the cup's high-fired body is durable but the unique surface patterns are best protected by gentle care.

We use careful packaging with multiple layers of bubble wrap, foam inserts, and a sturdy corrugated box to protect the cup during transit. The box is clearly labeled as fragile, and we take extra precautions to prevent movement inside the package.
