I am making soap for my mother-in-law's birthday, which is next week. She will be visiting us the following week. I had meant to get to this weeks ago, but it didn't happen. She knows about cure time, so it's OK. She loves lilac. After searching for a good half hour or more for my lilac FO, I realize I'm out of my preferred brand but I have two sampler bottles of lilac - one from BB and one from AHRE, both well-reviewed, there's just enough for my batch, so I'm off and running.

I figured since lilac can be a bit speedy, I'd try for a layered soap of darker and lighter purple (her favorite color). The color's a bit stubborn to incorporate but I SB for a good while before adding my fragrance and it's slow to trace. I stir in the FO with a spoon and the soap is perfectly well behaved. Hmm, maybe it's one of those FOs that actually slow trace. So I decide to go for a swirl. And I'm attacking it with the SB and it's poking right along. Finally I decide I've had enough and I start layering the soap in the mold, and it's still nice and fluid.

And then....

I've got more soap than will fit in my mold. Oops, what went wrong? I check my recipe (I had halved my normal 1800 gram recipe). Instead of writing 242 for water, I wrote 442. Oops. So 121 grams of lye to 442 grams of water, a ratio of 1:3.6 instead of roughly 1:2. That's some seriously wet soap. Full water in soap calc is about 1:2.8.

Will this even become soap?

I am CPOPing it in hopes that I will be able to cut it before 2015. For now, I've decided to let it saponify as an experiment - how much can you push your water amount without it completely falling apart?

Stay tuned for more developments as they unfold! If it works, the soap will be pretty. It it separates into a complete gooey mess and then I can just rebatch it and cook off the water.

Of course, I am now completely out of lilac but Peak Candle is close by and ships fast.
 
I obviously don't need to tell you, but holy smokes that is a lot of water! I'll follow along as I am interested in seeing what happens. Good luck :)
 
I am also going to follow along and see what happens. I recently did a similiar thing but ended up doubling the batch then made a couple more errors before finally getting it right. Think I have a thread with that one!! Good luck and I hope it turns out to be soap!
 
Well, color me amazed!

Last night I was already contemplating which method I'd use for rebatch - crockpot, oven, double boiler, to get evaporation as quickly as possible without getting too many dried out bits. The excess soap in cavity molds had gelled and cooled and, while solid, had a somewhat slick surface. The loaf had an oil slick on the top and when I gently poked the loaf, more oil seeped up and the consistency was extremely soft. I anticipated lots of oozy weeping pockets.

This morning, the oil on the top was reduced to a sheen and it felt pretty firm when I poked it. I decided I'd cut the soap so I could admire the swirls within before I mourned their loss in the rebatch. And the soap looks fine! No oozy pockets, no crystals. The top edge still has a bit of a sheen which I hope will reabsorb. I suspect it's fragrance that seeped because all of that extra water made the gel hotter.

I will zap test it in a day or two to make sure (with that much water, it's not like I need to hurry towards a rebatch)! No doubt there will be uneven shrinkage and they may warp or crack. Still, I feel extremely lucky right now!

Moral of the story - soaping when you are deeply stupid from seasonal allergies is probably not the best choice!

oooo that is such nice swirls!! i'm praying for no rebatch. purple can be a bit tricky sometimes.
 
Hoping you don't have to rebatch, because your swirls look great! I love it when they have that look of movement in them.
 
I'm cheering for you too, I love lilacs and those soaps are beautiful. A lilac scented soap for me is in my future plans and I hope I can do something that pretty.
