Lining a decorative mold

[SoapMom]

I was wondering if you can put a thin layer a vasaline on a decorative mold for CP soap. I have a great mold but its metal so I won't be able to get the soap out of it without lining it but I don't want to use paper or plastic wrap because it will destroy the pretty pattern. Any suggestions please!

Also would you have to line a silicone mold or can you just put the soap in? Just asking becuase I never have used one for soap before.

Don't use a metal mold for CP they are usually aluminum and talk about volcanic eruption!!!! Metal molds are good for M&P and rebatching.....

Glad I asked then! I wouldn't want to reinact Pompeii in my kitchen! Thanks!

I never line my silicone molds and the soap just pops right out.

Thanx for the answer to my second question! I thought so but wasn't for sure!

If you are using a rigid mould you can also place the hardened soap/mould in the freezer for a few hours and the soap will shrink which will definitely help to pop them out (just be careful not to freeze the soap becuase then it will sweat when is comes out ). If you like your aluminum mould you can coat it with a thin layer of brush on latex or silicone and that will prevent the lye/aluminum reaction as a barrier with the aluminum and it will be super simple to get the soaps out, as latex and silicone do not bond/stick to most materials. You can get brush on latex or silicone at mould/casting shops, sometimes art supply shops, and fibreglass shops, and maybe your hardware store if you have a really well stocked one. Or you can try silicone caulk as it is a lot cheaper than professional casting silicone and latex, but it would be much more viscous and hard to spread on well enough to catch detail and as it is a different formulation of silicone may not perform like casting silicone (might stick to aluminum or soap).

Not a pretty sight

Nope not a good idea. I managed it with Ribeana and lye. I am still amazed when I think back to that black horrible mess creeping up and over the container then flowing nicely over the floor as I calmly cleaned it up and it took ages.
How the calmness. It clicked in at that moment that any silly jerky movements would mean me burned and maybe new white cupboards destroyed.

If the mould is completely coated in latex or silicon (which hardens into a flexible and water tight skin) there should be absolutely no contact with the aluminum, and you would still be able to use your mould with a minor loss of detail. You could also use HP soap. I bake mine at 100C for 1 hour and the melted soap that results is generally fluid enough to press into a mould as long as it stays hot, a few minutes after it leaves the pot it will have a skin already developed and I can then press on the soap to help it to fill into the detail of the mould better. It obviously won't volcano because the lye has been used up, and if there is still lye in the soap after cooking you prob wouldn't want to use it anyway
