Q how is multichrome pigment made

Multichrome pigments, known for their ability to change color based on the viewing angle, are made through a precise and controlled layering process. This involves depositing ultra-thin layers of metal oxides onto mica or another suitable substrate. The thickness of these layers and the specific metals used (like titanium, silicon, or iron oxides) dictate the color-shifting effect. For example, a greater thickness results in a shift toward the red end of the spectrum. The production requires sophisticated equipment to achieve uniform layering and is a blend of art and science, varying considerably depending on the desired outcome. These pigments find applications in cosmetics, automotive paints, and coatings, offering unique aesthetic effects.

Q are pigment ink pads water based

Pigment ink pads, distinct from their dye ink counterparts, contain pigment particles suspended in a binder, which can be water-based, solvent-based, or oil-based. Water-based pigment inks are quite common due to their versatility and ease of use. They are known for their excellent opacity, vibrant colors, and ability to sit on the surface of the paper, making them suitable for use on various materials beyond just paper, including fabric and wood. Water-based pigment inks dry slower than dye inks, allowing for more time to work on stamping projects, but they also require heat setting on certain surfaces to prevent smudging. They are preferred for embossing and archival projects because of their permanence and less likelihood of fading over time.
