My wife recently got into kintsugi. She's learning the traditional method described here. I'm reading these comments with great interest and will be passing this onto her! Most of the methods taught in the US are "gold relief" methods, which is basically glue with golden pigment mixed in. It doesn't look great but is modern and quick. "Gold flush" methods take a bit more time and are more authentic, but still don't use the traditional materials shown in this article. Does anyone know where to get these traditional materials for use in classroom settings (i.e. in bulk, preferably discounted)? Not massive scale, just enough for a few classes. The kits have such a tiny amount and are so expensive, even a bulk discount of ~10-20% would be ideal.
