[QUOTE= However, remember that Chlorophyll was the first red sensitizer. I have seen it done! It isn't good, but it works!

Hello PE, I have been looking at chlorophyll, both suspended in water and extracted with methanol, with some success. I have been adding it as the final adition to the batches, and mixing at 45C for about 1/2 hour. Is there a better place to add the chlorophyll than at the end?
