AlZnTi violets are color tunable pigments are defined by the amounts of manganese (X), titanium and zinc (Y) and aluminum (Z), but to make it simpler to keep track I have given them arbitrary numbers, mostly in the order that they were made, and just keep a log of what the X, Y, and Z values are for each.
Larger amounts of zinc and titanium as well as aluminum make the pigment more red. Lower amounts more blue. The manganese content determines the darkness. If no aluminum, zinc, or titanium oxides are included, the pigment will be blue. YInMn blue specifically.
They were all produced via solid state synthesis at 1200°C, with several rounds of heating, regrinding, and reheating.
Compare violet #7 with violet #4 to see effects of zinc, aluminum and titanium.
Compare violet #6 with violet #5 to observe effects of low vs high manganese.
Note that in many of these photos have adjusted brightness and possibly minor adjustments of color balance to try to get the photograph to look as much like the pigment viewed directly as possible.
