Now the problem I've got myself into is that the popular kintsugi cult depends on repair with epoxy. Most epoxy is not food-safe. Food-safe epoxy is both extremely expensive and not, as far as I can tell, available in Italy. (But the fabulous French educator Alex has done a wonderful video about it.)
Going a bit deeper I learn that Kintsugi artisans from Japan are rightfully outraged by the "cultural appropriation" of using epoxy at all.
