I have been working on some testing on the Tenmoku Leaf bowl like the one pictured. I have tried several ways to accomplish this and the best tests came out when I placed a green leave into a freshly dipped and still wet bowl. I would glaze the stoneware bowl with my tenmoku and immediately place a green leaf in the still wet glaze. I tried other ways like brushing the leaf in on top of dried glaze and even dipping the leaf in the glaze. There were other ways I tried it also.
The best way was the way I described with pushing the green leaf into wet glaze. However I biggest problem is the leaf I have been using. Does anyone know the preferred leaf for this? I assume a broad thick leaf, but wondered if anyone here knows which is best? This being a Japanese or Korean technique I assume John may know.
