Well, I have to disagree with the Pink Sugar turning everything brown, in my experience the only thing it turns brown for me is soap and lotion. I use it in lotion bars, bath bombs, sprays, bath salts and body butters and none of them turn brown, or even tan, they keep their beautiful pink or white colors. I have some lotion bars from my original testers when I started making them in PS and they have not turned (over a year old). None of my bombs ever turn etc. I have PS sugar scrub and it doesn't turn either. In addition, the soy tarts I have from another candlemaker have never turned. Soooo...I don't know why they turned, did you use a ton of FO? It definitely sounds like they got to wet and turned into marshmallows on you, what did you have them setting on to cure? I will say, that although PS does not turn my products brown I have seen it react to metal and can get kind of rusty looking on the product (does that make sense?:undecided) So I never cure my bath bombs on metal or stainless. I don't know if this helped but it might eliminate the FO being the issue. Edited for spelling
