I've been experimenting using ABS as a mold for awhile and I haven't been able to figure out a way to eliminate air pockets. I do everything I can think of to keep air out of my soap mixture and this isn't a problem with my loaf molds. The last soap I made I banged on for an hour with a rubber...
I'm not exactly sure what I did wrong so I don't know. The calculator I used usually suggests around 28% lye solution. I'm guessing I'm closer to 20%. I probably did something dumb like switch between units as I recall doing a lot of tweaking while I was figuring out the batch
I got my calculations wrong on my last batch of soap. As a new soap maker I guess this was bound to happen. What I wound up with had WAY TOO MUCH WATER. I was hoping that I could just let it cure longer but the truth is I don't want my molds to be occupied for something that might never harden...
i use abs pipe for my molds and recently learned that uncapping at both ends helps it shrink down better when it's curing. some of the suggestions on here are interesting tho. i'll have to give them a try. cause usually it's just me and empty wine bottle and all the muscles i got
I've been using my drywall taping knife. It's basically perfect when paired with my miter box. and since it's 12 inches long I can often cut my loafs both length and crosswise
Thanks for all of the feedback. So after reviewing responses my mind is whirring with questions. I think the one at the top of my mind is how important is the water? I compared different solutions using the calculator on a simple 100% coconut recipe.
Using the 38% water in oil option...
I'm interested in trying to use this instead of the powder every time. I'm not sure how to make it work with the soap calculator though. If I select lye concentration and set it to 50% the value for how much water and lye to add are the same in the calculated recipe. For example next to water it...
