I can't find any consistency in what the temperature should be to mix the lye and oils/fats. The directions on Soapcrafters say that the oils should be 120 to 130 degrees and the lye should be at room temperature. The book "Soap, Making it Enjoying it" says the temperature of both needs to be between 95 and 98 degrees. The pvsoap website said the temperature of both should be around 110 degrees. Help! Which is it?!
Thank you.
