On these pictures you can see the process of the distillation of wine vinegar into acetic acid. First one have to freeze the red wine vinegar in a plastic bottle (s). Then put it upside down so that the acid that cannot freeze drips out. This process is repeated till it not freeze any more. When this is dome one distill what is left into acetic acid. Only about 5% is acetic acid so one needs quite a lot of red wine vinegar. Its obvious that there is more in it then the short description I gave but my goal is to show it on the pictures and hope they inspire the reader. This is not a formal instruction. For this it is important that one has an alchemical teacher or guide who helps in the process.
