Glass Urushi
Convenient lacquer in the shape of “I would be happy to have one”
Conventionally, the adhesion between lacquer and glass/ceramics is bad. Until now, methods have been used to improve adhesion by applying sandblast polishing, baking, primer treatment, etc. However,
- The number of processes is increasing, and it takes time, and money
- When treated with a primer, the thickness and texture of the paint come out, and the texture of glass, etc., changes.
- For example, when fine maki-e is applied to glass, the texture of the part that is not lacquered changes when the entire surface is polished or painted. Also, when it comes to masking parts that are not lacquered, it takes quite a bit of time and effort.
There were problems such as, etc. “Glass lacquer” solved that problem.

Our Adhesion Test Results ~Water Immersion Test~
Lacquer was applied to the glass plate, and after drying, those that had passed 1 to 1 week, 2- 2 weeks, 3- 3 weeks, and 4- 1 month were applied to water, respectively, and peeling tests were performed.
The tests were conducted with 2 types: colored lacquer (light yellow) and Kamiakuro, and the same results were obtained for both types. Normally, conventional lacquer does not adhere well to glass, and when soaked in water, it will peel off as early as 1 day.
- No peeling after 1 week to 3 months → feelings, places where nails stick
- No peeling after 2 weeks to 6 months → feelings, places where nails stick
- No peeling even after 3 weeks to 1 year or more → no nails
- No peeling even after 1 month to 1 year or more → no nails
