Bloody hell, I've been pork chopped by not one, but two bloody chemists in true enantiomeric fashion - on the left hand Mr Meat Thermometer and on the right hand Mr Bucket
I know too well that I could have detailed a 3 phase method for the facial toner, using weight for the volumes and a very high degree of precision but the fact is while you both would have enjoyed it everyone else would have taken one look and thought "F*ck this, you need all this equipment, glassware, a digital scale - this todras guy is just a science nerd" which while probably amusing and true, would have defeated the purpose of this thread which was as a DIY explanation and method that could be repeated at home.
If I do the more advanced toner, the method will be more complex by necessity but my intention will remain the same - to make the information and method accessible. You are both more than welcome to offer
achievable solutions to improve accuracy, method and results btw and your humour is noted you pair of pork chops
