Yay! Hope is always strengthened at the break of a new day.
Like everyone has said- we all make mistakes. I'll never forget the time in my earlier soaping days when I made a (predominately) canola oil soap and accidentally super-fatted it at 23% due to a silly brain fart. The soap actually felt super awesome and luxuriant on my skin, but, well, being predominately made of canola and all, it came down with the DOS shortly after cure.
And just the other day as I was HPing a batch shaving croap/soap I had another brain fart and forgot to add my FO before molding. Thankfully, though, I was able to rectify that right quick before my batter set up. Whew!
Ok,....whats the point in doing that?
Speaking only for myself, I master-batch my lye because it's the least favorite thing I like to do when it comes to soap-making. Just the hassle of making sure my mixing space is clear of living beings and is going to continue to be clear of living beings for a while, etc., and taking the extra care to make sure that all the safety protocols are in place (extra-protective gear, proper ventilation, etc..)
every single time I want to soap, is enough to kill the mood, if you know what I mean.
So, I make enough 50% solution to last me through several batches over the course of a month or so (or longer). Properly stored, it lasts a very long time without it's strength diminishing (at
least a year according to my experiments at any rate, more than likely longer than that I'm sure).
Sure, there's a little bit of extra math involved to figure out how much extra water to add to the solution in order to convert it to whatever different strength I'd like to use for whatever batch, but since I'm working from a 50% solution, the math is a very easy 2-part formula that works across the board for any different water strength I desire to soap with. I just type my recipe into SoapCalc at the water % I would like to use for my batch, then I perform the following 2-part formula:
1. Recipe amount of dry lye that SopapCalc gives me x 2 = how much of the 50% solution to weigh out.
2. Recipe amount of water that SoapCalc gives me minus the recipe amount of dry lye SoapCalc gave me = how much extra water to add to my batch.
It might seem complicated, but being able to reduce it to a simple working formula like that takes a load off my brain and turns the task into something very easily done....as long as I keep the formula handy! lol
