![]() On the other hand, they also seem to be more sticky and don’t dry as readily. I have found that Piñata inks are much more intensely colored and require much less ink to color the clay. Piñata Alcohol Inks by Jacquard come in a smaller range of 19 colors which includes black, white, silver and gold. The Bright range tends to be the most intensely colored. Ranger inks certainly come in a wide range of colors but vary in their intensity greatly from one to the next. You will most likely see 3-packs of bottles in your local craft store. Tim Holtz® Adirondack® Alcohol Inks made by Ranger come in 48 colors that are grouped into Earthtones, Lights, and Brights. There are two main brands of alcohol ink on the market. The bottom row is Ranger Purple Twilight. Comparison of how alcohol inks can be very different on paper, in unbaked, and on baked clay. It’s just one more challenge you face when learning about a new medium. Some colors may change even more when the tinted clay is baked. Piñata Passion Purple, on the other hand, appears nearly cobalt blue on paper but colors the clay a nice grape purple. But mixed with translucent polymer clay, it turns sort of a light plum color, or even a fuchsia. For instance, Ranger Purple Twilight is a nice grape purple in the bottle and on paper. Color FidelityĪnother factor to be aware of is that the color on the bottle of ink, and the color that it creates on paper is not necessarily what you’re going to get. Note that mainly the orange has diffused while the green and yellow stayed in one place better. The remaining sheet has been in storage for 4 months and the colors, originally on the surface of the veneer, have diffused. The top veneer of this amulet was cut from this sheet of polymer clay. Alcohol inks diffuse throughout polymer clay over time. So if this is a concern make sure you bake your project right away before the colors have a chance to bleed. I don’t see any signs of the colors bleeding in baked clay, though. Others might not show a problem for weeks. Some colors bleed more quickly (due to the size of the dye molecule), so it’s more apparent. ![]() This means you cannot use alcohol ink tinted clay in millefiori canes unless you are going to bake them right away. If you set aside your work for a while you will very likely come back to a homogeneous mess. Also keep this in mind when you use tinted clay in veneers and mokume gane stacks. Always make sure that your tinted clay doesn’t touch any other color of clay when stored. ![]() Given long enough the color will diffuse from one to the other and mix completely. However, two unbaked balls of clay tinted with two different colors of alcohol ink, if stuck side by side, will eventually mix together. If your mass of clay is all one color this poses no problem. The dyes in alcohol ink travel thought the mass of clay quite easily by simple diffusion. Plaques are light areas within the clay, sort of like imperfections. Also, some people have reported plaquing or mooning in the cured clay. It is a chemical additive and some clays, Kato Polyclay especially, can get quite sticky if you add a lot of alcohol ink. There is a limit to how much alcohol ink that polymer clay can “hold”. Even so, coloring translucent clay with alcohol inks gives a richness of color that is unlike anything available with colored, opaque polymer clay. There is a limit, however, and high amounts of alcohol ink will interfere with light transmission. You can therefore color the translucent clay quite intensely without reducing the clarity of the clay. Alcohol inks, because they are dye based, do not have particles to obscure the light. If you begin coloring translucent polymer clay with something that has pigment particles, such as oil paint, chalk, or colored polymer clay, at some point you are going to compromise translucency as you add more pigment and the intensity of the color increases. Translucent polymer clay doesn’t have pigment particles that block light transmission, that’s why it’s translucent. Because polymer clay is also soluble in alcohol, the dyes in alcohol inks readily disperse into polymer clay making alcohol inks a perfect material for coloring translucent polymer clay.
