I made this killer mistake in my last batch few nights ago, I accidentally used the water amount as soda amount. I couldn't understand why the lye turned very very thick, I had crystals floating on the surface not melting, I was trying to figure out what went wrong, I thought I have planned very well for the batch, I couldn't tell why the soap in the molds was heating up to 450 F. I didn't need to insulate or wrap the batch, it hardened extremely fast, I thought maybe I get up very early next day to cut it, so I went to bed to wake up around 4 am thinking what went wrong. Only then it clicked to my mind what I had done. The soap is very brittle I am thinking to make it into a powder and add baking soda and use it for washing whites. I know in the past they used lye for cleaning but I didn't try such a thing before.
