The video above explains everything. Cobalt human rights violations, which are happening right now and likely to increase, are unacceptable. I refuse to sit by and do nothing.
The best thing I can do to help solve these horrific problems is to talk about them publicly to our hundreds of thousands of followers, and minimize my use of cobalt blue.
I’m discontinuing this pottery, effective immediately, until further notice:
I will try to reformulate glaze chemistry to get blue without cobalt, but it’s unlikely I’ll succeed.
Blue Spiral Cosmic Mugs
There is also pottery that contains cobalt that I’m not able to discontinue today. For those pots, I’m working to reformulate my custom glaze chemistry to eliminate cobalt, but maintain beautiful blue colors. Those include any pot that has my custom “Oil Spot Black” glaze, specifically the “Cosmic” glossy black pottery, including all Cosmic Mugs and Moon Mug interiors for cosmicmugs.com.
Here is the exact glaze recipe for my Cosmic Mugs, with how much cobalt I use today.
Oil Spot Black, Cone 6-10
| Silica 325 mesh | 17.4 |
| EPK (Kaolin) | 8 |
| Calcium Carbonate, High Purity | 13.6 |
| Custer Feldspar | 47.4 |
| Bentonite | 4 |
| Red Iron Oxide | 8.1 |
| Cobalt Oxide | 2.5 |
| Total | 101 |
Some of my pottery will still require cobalt, like the Neptune Mugs, which I make about 100 of per year. But for the other 5,900 pots I make per year, my goal is to eliminate cobalt entirely. I can’t guarantee I’ll succeed, but I’ll try.

New blue pigment
Featured snippet from the web
And now, for the first time in two centuries, a new chemically-made pigment of the celebrated color is available for artists — YInMn Blue. It’s named after its components — Yttrium, Indium, and Manganese — and its luminous, vivid pigment never fades, even if mixed with oil and water
You are an awesome human being! I have one of these mugs. I can’t wait to see what your creative mind comes up with instead! Here’s to activism that makes a different in our world!
This is a great opportunity to play with other colors. Not being a “blue” person, looking forward to light Sandy colors w reds, greens, oranges.

I admire you for your stand on the use of cobalt from the mines in Africa. Last month the topic of the conditions in the mines was covered on NPR. Seeing the visual of the people working in that pit was startling and heartbreaking. Thank you for your stand.
I love that you are standing up to this horrible situation in the Congo.
Wow I am so moved by your willingness to make this stand esp as it effects you financially. And I appreciate that you are educating others as you do it. I am glad to hear of Cobalt Red and also commit to educating those around me and becoming more of an advocate for change. Thank you Joel
