How do you dry your bath bombs?

Recommended Posts

I am still testing out recipes (probably on my 15th recipe...) but I need a way to let them sit and dry and harden without the bottoms flattening out. Letting them dry in the molds usually works, but then I run out of molds and sometimes they stick to the mold as they set. I have also tried some bubble packaging stuff but they still come out a little uneven. What do you all find works well for you?

you Can use the foam egg crate material. But if your formula is right they won’t flatten much, if at all.

I agree with TT.  If your recipe is a good one they won't flatten much.  Mine (when I make them) just sit in a box on paper towels for 8 hours and they are good to package.

I found one recipe that gets pretty solid within just a couple hours, which I'm very happy with, but I have a few problems with it so I am trying to tweak it. If I post the recipe do you think you guys could give me some advice?

If you want. Sometimes it’s just a matter of how wet you are making the mix as you go.

I agree, perhaps you are just getting them too wet.  We can certainly look at your recipe and see if there's any glaring issues with it.

This recipe is my mom's favorite so far. It's VERY oily, probably too oily. like it leaves a but if a slick on the tub. After 3 weeks of drying in a dry climate I can push my finger into the bomb and leave an indent. It also sinks like a rock. 

 

1.5C BS

0.5C Cornstarch

0.25C Kaolin Clay

0.75C Citric Acid

 

1oz Shea Butter

0.8oz Sweet Almond Oil

1.5Tbs F.O. 

0.05oz Distilled Water

0.3oz Polysorbate 80

 

 

This recipe comes out pretty firm. If I leave it in the mold for like an hour or two it comes out pretty solid. I did one batch packed pretty tightly and I could probably play baseball with them, but they sink like a rock so I did another batch packed almost too lightly and they sort of bob. They start out floating and then they sink. There's also no noticeable silky feeling in the water so my mom didn't like them at all. They also don't fizz much.

 

500g Baking Soda

15g Kaolin

20g SLSA

250g Citric Acid (added at the end after liquid ingredients)

 

20g FO

20g Sweet Almond Oil

10g Distilled Water

4g Polysorbate 80

here is a link to a tutorial i did a while back that may (or may not) help.

I learned over time that I dislike fillers like corn starch. they cause more trouble than they are worth.

slsa slows fizzing and can be drying.

cream of tartar hardens mine up faster than anything.

 

notice on the vid I dried them on the counter directly, and no flattening.

I made these recipe awhile back TT is 100% correct, this was the first batch I made that held up. I am thinking it maybe due to the ingredients being in grams instead of Oz, more accurate. However I have been playing around with removing the Cornstarch, Cream TarTar, and the SLSA, for the reason she explained.

 

I use Bubble wrap, I get a lot of it free from items I ordered, so I just lay it out depending on thickness, and lay bombs on it for 24hrs.

TallTyl, for this recipe, did you use Poly 80 or DLS Mild?

I did batches with each. DLS mild presented a problem being that it is a liquid based surfactant. I had to really fluff fast to stop it from reacting before molding.

I don't love polysorbates, but they work.

I was wondering because I could not get my bombs to end up that hard. Still amazes me! I don't use cornstarch, or cream of tartar, but I use Kaolin clay.

Cream of tartar hardens mine really fast. You can drop them on a concrete floor and they won’t break. Polysorbates then to make mine mushy.

I too use Cream of Tartar with a bit of Kaolin makes a really hard bomb for sure and sturdy.
