Sagging in the middle
by Michelle Morgan
I did a 1.5kg batch placed it in a wooden mold and let set for 2 days. The soap had sagged in the middle by about 1/4 inch (5mm). What would cause the soap to contract so much?
Coconut oil 250g
Olive oil 250g
I'm not really sure to be honest but I will throw a couple of guesses out there.
Seperation can cause a cave like center in the soap which would cause a dip. You would have noticed excess liquid leaking out of the mold though.
Overheating can cause a lift in the soap but that usually occurs in the center where the soap gets hottest and not around the sides where it is cooler.
Perhaps your recipe had an excess of water? If the water evaporated quickly in a very hot environment during the 2 day insulation period, that could cause a warping or sagging look to the loaf.
Anyone else have any ideas?
