All WARPIGS brand pigments are non-toxic, naturally-occurring elements. WARPIGS pigments, like most others, come from a quarry located in France.
Natural Earths & Ochres are colors including Ochres, Siennas, Umbers and natural iron Oxides. Compatible with all mediums, these colors are permanent providing a strong depth of color.
Minerals are exclusive shades with a natural Ocher base unique to our quarry. Their composition is 90% Ocher/10% Mineral or Organic pigment. As with our Ochers, these UV resistant colors are compatible with all mediums and respond to light in a way that is unmatched by synthetic pigments.
Oxides include both organic and mineral Oxides. They are not found in the earth as natural clays, but are created using natural components such as minerals or organic compounds, that are manipulated, usually by heating. As with all our pigments, our Oxides are safe and non-toxic.
All of our pigments are ground to 50 microns for ease of mixing. They contain no cadmium, mercury, tin, arsenic, radium, lead or other hazardous materials. Our Viridian, Green MC and SOF Green pigments are Chrome Oxides. Some very sensitive individuals may experience skin irritation with prolonged contact.
Although WARPIGS weathering powders are non-toxic, care should be exercised to avoid breathing any dust generated by their usage.
Below are the MSDS sheets for each WARPIG color. Note that the ochres are all the same - the percentages of the minerals used dictate the color. You will need Adobe Acrobat Reader for these documents which you can get free by clicking the Adobe logo.
