Hi everyone. I am making baby favors that are sea creature theme. I have made some cp soap to resemble ocean water and then I put whales and dolphins that are mp on top. Pics included... My question is can I make salt bars with same technique? I would make them with salt in silicone cavities then top them with my whales, dolphins, crabs etc. 3rd pic is salt bar that I would make but use mp whale or dolphin on top. I am asking because I don't want to waste all the material if the mp reacts to the salt/soap batter. I don't feel like taking the chance as my time is running out to make the order. I have decide which is best method. Thanks in advance!
