heavy metals in dye
  • Hi all-I have used J. acid dyes and really like the predictable results and colors. I was wondering if anyone knew where I could get information about the heavy metals in the dyes? I know some turquoise colors need copper to dissapate (or something lol!) but what about the other colors?
  • Okay-so does the portion that states it contains less than 50ppm lead mean it has a extremely (less than 50ppm lol!) small amount of lead and is this what helps make the turquoise so vibrant? I only ask because I have read somewhere that a vibrant turquoise type color needs some sort of metal to help it along?? Not real scientific I know, but I was just wondering.
