ty all for the quick responses. I cut up my soap log and the gold that is in the centre is just fine. I contacted my supplier and it is 24k gold flakes used in cake decorating. the only ones that have changed colour seems to be the ones on the outside. could it have something to do with the air?? the lye and the oils are both combined at a temperature of 95 to 100 F. I didnt think that would affect the gold. This is such a mystery to me!!

Hi There I make cold process soap and use a lye solution to saponify the oils. I made a batch yesterday and added 24k gold flakes. They have all turned black. Is it possible for the lye solution to affect the gold in this manner? I have checked with my supplier and they are 24K. I am not sure how to avoid this. Any help would be appreciated!
