Being very interested in ash-based work, I had set myself the goal of finding a recipe for Tenmoku (black glaze with a high concentration of iron oxide) to work on ash-based glazes overlays.

With the help of Daniel de Montmollin 's book "Pratique des émaux 1300°C", I decided to start researching diagram 33. I made my first test tubes, going through the diagram and varying the concentrations of iron oxide. Here's what I get: (the red dot near the sample indicates the one selected for further research)

On the sample, red spots appear. I hypothesize that this is due to the thickness of the enamel, which is thinner in this area. So, to test the hypothesis, I take the formula of this sample and double the quantity of enamel deposited on the test tube.

I then proceeded to a finer test of the iron oxide concentration:

The last test tube (bottom right) corresponds to the concentration used in the previous tests. From this result, I deduce that the concentration used during the first tests is satisfactory to make my Tenmoku.

Some discoveries appear after many hours of research and discouragement, while others, like this one, are due to chance or luck. The story behind this glaze is simple: I had developed a flowing white glaze that I applied to black stoneware. I said to myself: "Let's try this glaze superimposed on the tenmoku". and the result was as follows:

"Yes it's not fair you'll tell me, but that's the way it is!"
