Earth Pigments

Category: Earth Pigments

All of our earth and ochres are natural. Some of our oxides are natural, some are synthetic, same goes for our mineral pigments. ALL of our earth pigments are non-toxic and mimed or created in an environmentally responsible way. They are designed to replace some of the more toxic pigments e.g. cadmiums, in your art work or painting.

Yes, but mixing too many colours together will usually result in ‘mud’ or a dull colour. So mixing needs to be done with care, and experimentation with small quantities, and testing is encouraged.

Yes, our Earth Pigments are perfect to use to tint lime, clay, cement and gypsum plaster. Due to the alkalinity of lime, some pigments tend to fade more quickly. There is more detail in the individual product pages, but please choose lime stable pigments if you are working with lime. The UV stability is also listed on each product’s page, and please consider this if the pigment is for outdoor use. Those that are NOT recommended for outdoor use are marked as such, and there is a category called “Not for Exterior” for these pigments.

We pack all our pigments by weight, so you can be assured you are getting exactly what you paid for. Different pigments have different densities, and so some take up more space than others. So some jars look more full and some look more empty than others. You’re still getting the correct amount by weight.

No, pigments and dyes are not the same thing. Pigments are insoluble colorants that are suspended in a medium, while dyes are soluble colorants that dissolve in a medium. A solution of pigment will be cloudy, while a solution of dye will be transparent. Pigments are often more opaque and can cover the underlying surface more effectively, while dyes are usually more transparent and allow the base colour to show through. Pigments tend to be more lightfast, meaning they resist fading when exposed to light, while some dyes may be less resistant to fading.
