Over the past few weeks, I tried to achieve this effect using iron under dots applied under or just beneath the glaze. During firing, the iron melts and spreads slightly, with the center turning dark brown to nearly black, and the edges developing a subtle rust-like hue.
In my first attempt where I applied the iron very thinly, it flowed almost like water. In the areas where I applied it thickly, bubbling and separation from the surface occurred.
For the second attempt, I hadn’t planned on doing it but out of impatience I quickly added it to my Cone 6 kiln. The result was a dark blotch; without sufficient flow, the effect lost its vitality and looked unattractive.
For the final attempt, I refined the recipe and fired it at Cone 9. The effect I was aiming for finally appeared. The centers were dark, almost black brown, and the edges had a delicate, warm rust tone. The iron remained slightly flowed but maintained its form, creating the lively, balanced effect I had envisioned.The glaze itself was quite thick almost the consistency of yogurt, which added to the depth and texture of the effect.
Red Iron Dots Recipe
Red Iron Oxide – 45 g
Frit 3124 – 40 g
Kaolin – 15 g
Silica – 22 g
Gerstley Borate – 10 g
These small but effective adjustments allowed the iron to move naturally beneath the glaze, giving the surface a sense of depth and life and making each piece feel unique.
This week I also filmed a video for YouTube capturing my experience making a ceramic piece from start to finish. Now I’m waiting for the glaze to be fired but it was a great experience and I’ll be sharing it soon. I might also return to sharing on Instagram though writing here feels more personal and comfortable for now.
