Your wonderful answers seem to bring up more questions! LOL I see soapers on you tube videos, just squirint some titanium dioxide mixture into their soap, so I"m assuming they just add enough to get the color they want, but not by any pre-set % or weight. Is this what you all do?
Other questions: Can I also use Titanium dioxide to lighten a color. For instance, I'd like to get peach or apricot but I don't see those as available colorants. So will using some TD in an orange colorant give me a peach or apricot color?
I know that too much TD can cause the soap to go more into an orangy tone (same thing when you use a lot in some ceramic glazes). So is there a maximum amount to use to maintain the white color and avoid it going into those orangy/yellowy tones?
Also, if they have a large batch of pre mixed TD, then how do they figure the extra oil that is going into the soap when they are only using a small part of that pre-mixed batch; or do they just not concern themselves with the extra, carrier oil.
So much to learn!
