This is my Alizarin Orange (Madder Orange) lake pigment that I researched and made over a period of two to three years in the past. It is made from Nitroalizarin, which is produced from the reaction of Alizarin powder and Nitric acid. Since last year, we have discussed this with Pierre @pierre_flavetta_luthier several times, and he has developed another process that is more effective. I can't wait to see it!
