Caffenol with Tea

If you are reading this blog, chances are that your already know what caffenol is. In case you don't, it is a developer made from a mixture of coffee, washing soda, and sometimes vitamin C. You might already know that in this "recipe", you may substitute coffee for tea. Some on the interwebs have done this before, however the quality of the results has never really been established. So I thought I would have a little science project, comparing caffenol with coffee, caffenol with tea, and standard Ilford Id-11 developer. More on this experiment later.
