Pilot Just Turned a 400-Year-Old Japanese Craft Into Living Art - Yanko Design

"The entire surface of the porcelain vessel is coated with Pilot's thermochromic ink, the same temperature-reactive technology they developed for their erasable pens. At room temperature, the vase appears as a deep, rich navy blue. But pour in hot water, and something magical happens. The heat triggers a color transformation that gradually reveals a stunning celadon glaze underneath, one of the most prized colors in traditional Arita ware."

"What makes this particularly fascinating is how the change unfolds. It's not an instant flip from one color to another. The transformation is organic and unique each time, with different patterns emerging as the heat spreads through the ceramic. Then, over the next 30 to 60 minutes, you watch as the color slowly returns to its original deep blue state as the water cools. It's like having a living piece of art that breathes with temperature."

"Thermochromic ink has been around since the 1970s, initially showing up in novelty items. The technology works through leuco dyes that change their molecular structure when heated, typically becoming translucent or shifting to lighter shades. Pilot has been a pioneer in this field, particularly after developing erasable ink pens in 2006 that used thermochromic properties to create ink that disappears above 65°C."

TimeVase is a collaboration between Pilot Corporation and Arita porcelain artisans that combines thermochromic ink with 400-year-old ceramic techniques. The porcelain surface is coated with Pilot's temperature-reactive ink, appearing deep navy blue at room temperature and revealing a celadon glaze when exposed to hot water. The color change unfolds organically, producing unique patterns as heat spreads through the ceramic, and reverses over 30 to 60 minutes as the vase cools. Thermochromic technology uses leuco dyes that alter molecular structure when heated, and Pilot previously applied this property to erasable ink pens that disappear above 65°C.
