Thank you for this invaluable demonstration! A most fascinating look at how simple it is to use the fine, traditional methods of yore! And that blue!! Absolutely divine!
If you use a roman soap solution, or a casein water solution while doing the levigation process.. it allows the pure azurite pigments to sink much faster, and for the impurities to stay up top. It also allows for a much more of a pure pigment ( traps that gritty sand particles, and impurities) and much easier way to seperate the particle sizes... faster and cleaner. Just a tip to think about, or use. Cheers mate
