Q: What is the color index? Is this color lightfast? Is this a granulating pigment? Is this non-toxic? Is it staining?
A: The color index number is PY0741. This pigment loves to lump up in water, unless it is dispersed with a small ratio of denatured alcohol in the dispersing water. It is classified as non-toxic, since it does not contain any heavy metals. It is not water-soluble and therefore can not stain.
Q: Hello, I spoke with a gentleman by phone a month ago, I am exploring encaustic painting and interested in mixing my own colors. I believe I was told that the dry pigments can be mixed with wax medium to create color blocks. Please let me know if that is correct, and if so what the recommended ratio of pigment:medium is best for achieving bright opaque coverage. And is the pigment added to the molten wax and stirred? Also let me know if mixing pigment and medium is not the way to go, and if not, what are alternatives. Thanks for any help you can be! Layne
A: The pigments simply need to be mixed with molten beeswax, in order to create your own encaustic color blocks. The ratio of pigment to wax depends on the pigment tinting strength and the opacity. For example, this Hansa Yellow has a high tinting strength and therefore only a small amount of the pigment would be required to tint a large amount of beeswax. A 20g jar should be more than enough for a pound of beeswax.
For tinting strength information on other pigments, simply click on our individual pigment listings and the tinting strength will be listed in the description.
Q: Please indicate COLOR INDEX name on your pigments. I advise my students to NEVER buy pigments if they do not know the CI name. Knowing the CI name allows them to refer to the ASTM standards for lightfast ratings. What is the CI name of DC0741 Brilliant Yellow (Hansa) Warm Primary Yellow?
A: Hansa Yellow is a rather standard color and most artists know it as PY0741. We always advise our students NOT to paint by the numbers.
