Bath bombs still cracking

[Minki]

Hi there,
I have tried everything and my bath bombs are still cracking. I've come to the conclusion that it must be the way i twist my moulds when I'm making the bombs. But how else do i get them to stick? I'm using custom moulds I've had 3D printed. I don't have a bath bomb press.
I'd love suggestions please.
Many thanks!

I use small, individual silicone soap molds for mine. I call them bath tabs. What is your recipe? You may be using too much liquid in the mix. I use cocoa butter and have never had a problem with my tabs cracking.

I agree that cracking means too much liquid, which is opposite of what most people think.

I find it easier to make them with a mooncake press, or to pack them into small silicone cavity molds. Those shapes are also easier to package than the spheres.

I use a moon cake press but most recently am having good luck with stainless steel one-sided molds.

If you twist the mold, that usually separates both halves, what shape is your mold ?
and does it have an outside wall that contains the inner shapes like most 3d molds?

Do you include cream of tartarin your recipe? That usually helps
