R626
Black with brown or blue dots.
| A very good glaze that I have worked with a lot last winter. Apply rather thick. Works well in oxidation an then gives a semi transparent to opaque glaze with a lot of blue. In reduction it gives a more opaque glaze. You can use it on white porcelain to dark brown stoneware clays. On brown clays it must be very thick to give blue patches. |
