Can beer cause overheating?

[CamillaHB]

I have just made two batches (different recipes) of beer soap (with Guinness). I used muffin size silicon molds, put the soap in the oven at 50 degrees celsius and turned the heat off.
In both cases I got droplets of oil on top of the soap as if it were overheating (I suppose).
I find this a bit strange, because this procedure has worked fine for me in other cases.
Now the question is: Does the beer cause overheating? Should I just leave the molds at room temperature without insulation or anything to achieve gel but avoid overheating?

Yes, beer can cause overheating. I generally don't insulate my beer soaps. I also boil the beer until it is flat and reduced to about half its volume. I mix my lye with water (half the total liquid amount assuming a ratio greater than 1 lye: 1 water). After it cools, I then add my beer. It can heat up again and even volcano so be sure your vessel is large enough to accommodate that possibility.

Hope this helps!

Thanks!

I froze my beer and let it thaw a bit, so it looked like slush ice. After adding the lye, the temperature was about 40 degrees Celcius. No volcano or anything

Do you think there is a chance the oil will reabsorb and my soap will turn out OK after all?

i had the same situation with honey soap, it was overheating and oil on the top, it did absorb back, takes little longer to cure, hope that helps
