How Does It Work?
DUAL (HOT & COLD) - These amazing little cups will react to both hot & cold liquids. All Sakura, Peach, and Plum trees will bloom light pink when hot, and a detailed blue when cold.
An Artisan's Subtle Nod to Tradition:
Crafted and hand-painted by local Japanese artisans and inspired by artworks painted by Kitagawa Utamaro. Each 'o-choko' (sake cup) is painted with a special non-toxic thermochromic pigment ink and then coated with a food-grade clear ceramic glaze, to seal in the color-changing ink.
Color Changing Feature: The color changes when the temperature of the liquid is either above 103°F (for the pink tree effect,) or is below 70.5℉ (for the blue tree effect.) The pigment is made with temperature-sensitive materials that are painted on the cup body and coated with a clear glaze. They have a high-temperature resistance of 608 °F, they are non-toxic, BPA-free, lead-free, chromium-free and meets the FDA/EU standards.
Due to the delicate thermal reaction, there are cases where certain parts of the world are too hot or too cold that the cups arrive fully bloomed and activated out of the box.
In this case, we recommend to serve them at a different season or apply a heating or cooling method to reset the cups back to their original blank white with branches. Gentle hand wash is recommended to preserve the longevity of the cups and ink design, dishwasher usage is not recommended.
