In my quest to come up with a glaze recipe that is as close to the old Chinese Blue used by the Jugtown Pottery era of the Busbees, and Ben Owen Pottery, I have made, and fired, several tests. Despite having a chemical analysis of the original from the 1980's, its been a challenge even using glaze calculation software. And what I have found is that the test I had formulated back when I was working for Ben, III shows the most promise. There is still the need to tweak the recipe, for various reasons, but I feel that I am close to something that will be satisfactory. Here is a cup that I just got out of my wood/gas conversion kiln. The one thing I have noticed in doing these various tests is the importance that wood firing plays in achieving the color of Chinese Blue.
