My issue is that if I had only had Catherine Failor as a source of instruction as a new liquid soap maker, I would have thrown my hands up and given up. However, I benefited from other sources of information. I can, now, appreciate some of her info. But she does not make her info readily available in a methodical format for the new soaper. And her methods are, I repeat, unnecessary and outdated. We have ways to ensure complete saponification that do not involve making lye heavy soap and then neutralizing. I am not saying that she did not contribute GREATLY to the home soapmaker for making liquid soap. She did. It is just that we have much easier, and less intimidating to new soapers, methods of making liquid soap.
