Kintsugi is the art of beautifully mending broken pottery and prolonging its life. Kintsugi is a traditional Japanese method of repairing ceramic using lacquers made from natural resources. The word “kintsugi” means “golden joinery.” Historically, whenever the need arose, a skilled artisan would mend tea ceremony pottery with a special lacquer made from gold or silver powder. In modern times, more and more people are taking an interest in challenging themselves to try kintsugi techniques. My own workshops in Japan, which I call “The Kintsugi Club,” were created for those curious about this unique art. It’s exciting to see this curiosity taking hold in the West. In this book—just as I do in my workshops—I introduce both beginners and intermediate kintsugi aficionados to a DIY approach to making lacquer and applying it using various kintsugi methods. Four essential pillars of my approach: 1. Traditional: we will incorporate historically accurate techniques using real lacquer called “urushi” 2. Safe: we will ensure the least amount of harm, which means not using paint thinner or benzene 3. Enjoyable: it will be fun, easy-to-understand, streamlined 4. Economical: since mending is the goal, we will use kintsugi in the most cost-effective way With the above in mind, my goal is that anyone will be able to learn kintsugi at home with accessible materials and tools. Even if it takes a little extra time and effort, mending a much loved piece with your own two hands is a joyful endeavor. I invite you to take a whole-hearted dive into the art of kintsugi. —Michihiro Hori 5 Photo Gallery Mid-Edo period, exported Koimari Sometsuke bowl.
