Today is the day we strain our soapwort extraction, which is the main ingredient of our Shampoo/Skin Wash 01. We have two large vessels in our workshop, one of which can heat liquids to boiling point. Yesterday, we put a basket of the washed soapwort into this vessel and after it had simmered in pure, distilled water for the appropriate period we left it overnight to cool down. This afternoon we will slowly transfer it to the second vessel and add the other ingredients. If we transfer the liquid soapwort extraction too quickly it will become sudsy like a bubble bath and we will have to abandon our workshop until the foam has disappeared.
