I was feeling to make a very rich and wonderfully scented rhassoul soap that would have a simple but nice aspect (only a line of red mica that would "cut" the dark beige colour given by rhassoul).
So I made the soap. All was working very well : I poured the soap and sprinkled the red OXYDE. Then, when I poured the rest of the soap on the red "line", woups ! I saw that the trace was not enough heavy. I thought : ok, I will swirl all that and this will still be very nice. I put the batch in the fridge and well, the soaps are very nice except that I will have to throw away (?) the whole thing because the red oxyde tints everything.
I don't know where was my brain, as I did not realize that I was using oxyde instead of mica. I think that it takes a lot more micas than oxyde to tint c.p. soap... I have used something like 3/4 teaspoon of red oxyde for one kilo.25 of soap (maybe less...) The swirl is very nice, but it will tint the washclothes in red. (this soap is good for cooked lobsters)
I made some soaps in the past with a line of micas and everything has worked well. I think that oxydes (neither ultramarines) should be used for this purpose. I feel sorry because I had used pretty expensive e.o. and the blend is very good (IMO). One of the very few times since years, where I feel to thrash a batch...
