Well, after successfully hardening the clay into ceramic, we began testing the pieces (a regular clay for control, and a TiO2 coated piece) using methyl blue. We had a surprising reaction because the TiO2 absorbed some methyl blue, which didn’t bleach as we exposed it to UV light. The methyl blue solution did degrade some for both the control and the coated piece. However, there were still trace amounts of methyl blue for both samples after 6 hours. I got to use a UV photospectrometer to analyze the samples, which was pretty awesome.

We tested Saturday to get data, and we started another reaction today. Hopefully, we’ll get better results!
