I'm speechless

Some days ago I started testing thyme as a possible developer agent. I had a rest of it in my spices shelf, only 5 g of it. I made a tee with this amount of thyme, add some Potassium Carbonate and developed a stripe of B&W film, an expired TMax400 I bought at ebay. Although I gave one hour of development time, only a very faint image was to be seen:

I scanned it in color mode because the negative had the base color of a color film after development. I even thought the image could be in color.

Yesterday I brought 30 g of thyme from the supermarket and made a very concentrade tee, only 300 ml of it, enough to develop a 35mm film in a tank. I added about 15 g Potassium Carbonate to the tee and developed 2 hours long a 3 pictures-stripe of TMax400 exposed at 50 ISO. The result was the contrary of the first, a very dense and fogged film from which I could extract the pics, among them this one:

I underestimated the power of thyme, it was not necessary to develop so long an overexposed film. So, again to the work, 3.rd attempt to get the stuff working like it should. Reduction of the developing time to one hour, using 1g Potassium Bromide as antifoggant and leaving the rest as before, 50 ISO for TMax400.

I was not counting on this result, but that is what I get: almost COLOR photos!!!

P.S. - If you want to take part on a «pear-revue» and replicate the experiment, please write me in private, I will be pleased to give you the recipe you should use and other details.
