Thanks P.E.,
I am not trusting my life to chlorophyll as a red sensitizer, but I do want to try it. I also need to RE-TRY SDA-3057. This time at your recommended higher concentration and temperature. I have not been able to try anything this past week because I have been low in AgNO3 and low on time. But I expect to give them both a try this week.
I am storing both the SDA 3057 and the SDE 8006 at 1% in methanol, in brown glass at a temperature close to 0 degrees C. The SDE 3008 comes partly out of solution , even when brought to room temperature. But warming to about 100 degrees F redisolves it.
Has that been your experience?
Bill
