I got to the home page just fine now. http://soaphutch.com/
Rich has a notice on the front page.
Special Notice! - 12/15/10
SoapHutch will be suspending production for new orders of Soap Molds and Cutters on December 31, 2010 until April 1, 2011.
You have to use at least minimum water required in a soap calc for the lye to dissolve. Otherwise you will end up with undissolved lye crystals in your soap with dire consequences. Water is used as a carrier and it is needed for handmade soaps.
Most of it does get saponified. Lye does not discriminate. I would not add any oil after the cook. It might not incorporate and the LS will end up cloudy.
I would get a thermometer. I've been making soap for a long time and no longer use it, but I know if I touch the side of the pot and it's warm but not hot, I know I'm ready to go.
